Abstract

Currently, steel is widely used as a starting material in the high-rise building structure because it is more effective and efficient. Otherwise, steel has some drawbacks i.e. prone in collapsed due to dynamic loading. Therefore the aim of this research is to determine of response structure due to dynamic loading. The model is an Open Steel Frame building with a height of 35 m along 10 floors. The type of dynamic loads is harmonic sine and cosines, El Centro earthquake. The dynamic loadings are more precise when they were analyzed using the nonlinier time history method. The harmonic loads on the earthquake load structure are magnitude P0 1 kN, 5 kN and 10 kN load, meanwhile used the history of the El Centro earthquake. Dynamic loads that work suddenly, caused the structure undergoes deformations are not fixed and always have a change within a specified time. The results of the study showed that of these three type of loads, the maximum displacement is 143,885 cm, the maximum velocity is -519,599 cm/dt and the maximum acceleration is 3197,623 cm/dt2 load of the structure caused by sinus. Based on this study it can be concluded that the maximum displacement, velocity and acceleration of a maximum load harmonic sine and cosines is directly proportional to the variation of the value of P0 values getting bigger because then the greater the deformation structure anyway.Key words: dynamic loading, response structure, harmonic loading, time history

Abstract

Earthquakes are dynamic loads that greatly affect the state of the building structure. If the strength of the building can not withstand the dynamic load, then the building will be damaged even will collapse. The purpose of this study was to identify the structural response in the Indonesian quake region by using nonlinear dynamic analysis. Structural modeling using Banda Aceh, Bengkulu and Pekanbaru earthquake locations with medium soil condition on a 10-storey building made of steel with a constant inter-floor height of 4 m. Time history analysis in earthquake plan using 3 accelerated earthquake accelerator, namely: Kobe, Imperial Valley and Chichi earthquake. Each earthquake accelerator was given three treatments: 1). The earthquake scale is decreased by 50% (0.5 g), 2). Normal earthquake scale (1 g), and 3). The scale of the earthquake is increased by 200% (2 g). The analysis results show that the displacement, velocity, and acceleration of earthquake-load structures in each region are directly proportional to the increasing or decreasing of the earthquake-scale in buildings that do not occur in plastic joints.Keywords : steel portal structure, response, displacement, velocity, acceleration, time history analysis

Abstract

Bomb explosions in Indonesia have occured relatively more frequently and become a real threat to society. In the blast phenomena, loss of life and injuries to occupants can result from the structural collapse. Therefore it were necessary to do an analysis of the effect under blast load on the building with the aim of this research was to analyze the condition of the frame on a structure based on analysis of internal forces and structural response due to blast load. The building structure model was a steel frame structure of 5 story with a typical floor to floor height of 4 m. Variations of explosive weights of 500 kg and 1.000 kg of TNT were applied to a building structure model have converted into a static load at distance 25 m of blast source. To define the blast load on the structure, ATBLAST software will be used, and to determine blast load parameters need to be calculated with Pythagoras Theorem based on TM 5-1300-1990. Analysis was performed with Finite Element Method (FEM) software with linier static method will be used, the results of analysis were axial and moment force. The axial force was 621,28 kN, moment force weakness axis direction was -665,93 kN-m and moment force strong axis direction was 0,48 kN-m. Based on this analyze it can be concluded that the internal forces have occured proportional to the explosive weights of the building structure and frame conditions in the structure model was considered still allowable to received blast load of 500 kg TNT, however for the 1.000 kg of TNT explosive weights, structure model was collapse.Keywords: Blast load, inform force, linier static

Abstract

Indonesia is one of the countries that located in the quake zone. But not all earthquakes that occur is a devastating earthquake. Some earthquake parameters that affect the level of damage from a building structure are the peak ground acceleration, response spectrum value, earthquake duration, and earthquake frequency content. The earthquake frequency content parameters were considered the most influential on structural damage. The objective of this research is to get the response from the structure of multilevel steel portals such as displacement, inter-story drift, velocity, acceleration, and to analyze the displacement limit based on SNI 1729-2012. The reviewed structure is an open frame steel building model that is into 5 levels, 10 levels, and 15 levels. This study use time history analyses with 9 earthquake recordings of the Kobe earthquake, Mexico earthquake, Nepal earthquake, Chile earthquake, New Zealand earthquake, Sumatera earthquake, Fredericksburg earthquake, Mentawai earthquake, and Northridge earthquake that has been grouped into low-frequency content, medium frequency content, and high-frequency content. The results showed that the structure responses such as displacement, velocity, and acceleration will increase with the increasing number of levels of the building structure. The inter-story drift the allowed level of the structure still qualified based on SN 1729-2012 where the allowed drift in 7 cm and the inter-story drift produced by the structure is still less than 7 cm. An earthquake with low-frequency content has an enormous influence on the structure response in all the level structure.Keywords: response structure, time history, frequency content

Abstract

High temperature changes may occur at the time of the fire. This can result in discoloration, cracking and loss of strength on concrete. Therefore, a test was conducted to identify the changes of concrete compressive strength. The concrete compressive strength was measured by using Ultrasonic Pulse Velocity (UPV) and Compression Testing Machine (CTM). The specimens used in this study was cube with the size of 150???? 150???? 150 mm. The specimen used consist of 18 cubes with the expected concrete compressive strength of 20, 25 and 30MPa. And then, the specimens were burned in a local brick furnance for about 30 minutes. The test results of post burn concrete, indicated that there was a decrease in the concrete compressive strength for all specimens. Based on the test results of post burn concrete using CTM and UPV, there was a significant difference. On UPV test using Mahure’s Equation compared with the results of CTM has a difference 7.3, 4.4 and 12.5 MPa. Whereas if the test using Nash't’s Equation compared with CTM has a difference 7.1, 4.7 and 8.6 MPa. Therefore, it can be concluded that to identify post burn concrete compressive strength usingCTM more accurate than UPV.Keywords: Compressive strength, concrete after burn, Ultrasonic Pulse Velocity (UPV), Compression Testing Machine (CTM).

Abstract

Semi precast reinforced concrete (RC) used as an alternative in developing infrastructure is an excellent innovation, because of the advantages of this system can significantly reduced cost and construction time. Semi precast reinforced concrete (RC) beam is a combination of precast concrete which consists of the support beam and curve tile with the cast in place concrete. The elements are applied as a T-beam because of the interaction between the platesand the beams become unity. The study aims to identify the effect of the support beam and curve tile on the T-beam towards load-deflection relationship, curvature-moment and crack pattern caused by pure bending moments. The results showed that the load attained from finite element analysis was 56,664 kN while the load attained from strip method was 56,810 kN. Meanwhile, the stiffness value of finite element analysis was 1,206 kN/mm while the loadattained from strip method was 1,210 kN/mm. The collapsed pattern on the T-beam analyzed by using Extended Finite Element Method (XFEM) was a pure bending crack at the most significant bending moment region. The crack pattern showed the crack on the tension side of the beam in the direction of the stirrups.Key words : T-Beam, Semi Precast, FEA, Abaqus CAE, Bending Moment, Curve Tile

Abstract

Concrete exposed to high temperatures decrease its strength. Droped down in concrete strength under strength requirement will make the concrete fail to be functioned. The strength of the concrete can be determined from laboratory test, or mathematic model based on the results from experimental test. This study aims to identify the behavior of the stress and strain of the concrete exposed to high temperatures. The model was carried at using Finite Element Software LUSAS and the results compared to mathematic model proposed by Li and Purkiss (2005) and Chang (2006). The speciment used in this study was cylindrical with diameter of 150 mm and height of 300 mm with a 25 MPa of the concrete strength. The model was simulated burning with a constant temperature that varied from 100°C to 800°C. The result showed that strain stress curve shown from the empirical formula has an elastic phase of 0.6f'c, while modeling based LUSAS has an elasticity phase of 0.45 f'c. The difference between the elastic and plastic phases in the LUSAS model was clearly visible according to the temperature of the concrete, while the models using the empirical formula were not affected by temperature. It can concluded that empirical formula model and LUSAS can be used as a reference for the behavior of concrete when exposed to high temperatures.Keywords : modeling, high temperature, stress, strain, LUSAS

Abstract

Bagasse is a waste material and the use of this material for construction is still limiterd. In this study, fiber extracted from bagasse was used in teh concrete. This research aimed to examine the mechanical properties of concrete, namely compressive strength, bending strength and split tensile strength. The percentage of bagasse fiber used was 0.3%, 0.5% and 0.7% of the weight of coarse aggregate. Compresive strength was tested on the age 7 days, 14 days, and 28 days, while the flexural strength and split tensile strength were tested on the age of 28 days. Workability test conducted on specimens contained 0.3%, 0.5%, and 0.7% of bagasse showed the volume of slump at 8 cm, 6.5 cm and 4.5 cm. In testing the compressive strength of concrete, the highest value was produced from normal concrete which was 22.92 MPa.The value of flexural strength of concrete increased by 9.47% from the normal flexural strength of concrete with the addition of 0.5% bagasse at 4.45 MPa. Different with the value of concrete split tensile strength, the highest value was obtained in the addition of 0.3% bagasse, which was 2.21 MPa with an increase of 19.48% of normal concrete. This research concluded that the addition of bagasse fiber can reduce workability.On compressive strength testing with the addition of bagasse fiber, the compressive strength was lower than that of normal concrete but still within the range of concrete plan quality 17 MPa. Addition of bagasse fiber to the concrete mixture could increase the flexural strength by 0.5% and split tensile strength by 0.3%.With the addition of bagasse fiber to concrete, it is hoped that bagasse waste can be utilized and concrete quality is achieved Keywords: Fiber Concrete, Bagasse Fiber, Split Tensile Strength, Flexural Strength, Compressive Strength

Abstract

Light brick is a brick that has a specific gravity ranging between 600 to 1600 kg/m3. Light brick has the main raw material consisting of sand, cement, water, coupled with a foaming agent material. The aim of the study was to obtain the composition of the optimum light brick mixture which resulted in maximum compressive strength. The compressive strength of the lightweight concrete was measured by applying compression displacement-controlled loading system. The mixture of each composition for the lightweight concrete used in this study was compliance with Ministry of Public Works module for lightweight mortar technology heap foam material for road construction. Light brick composition was varied based on the percentage of foaming agent and sand. The optimum composition has 25 kg cement, water as much as 13 kg, sikament NN 200 ml, sand as much as 64 kg and foaming agent as 5.7 kg of 12 samples of the test specimen. The compressive strength of optimum composition at the age of 3, 7, 14 and 28 days was 0.264 MPa, 0.364 MPa, 0.511 MPa, and 0.648 MPa, respectively. Based on test results, it was concluded that the addition of the foaming agent and sand would increase the compressive strength of the light brick.

Abstract

The increasing in the population has an impact on the increasing of housing or bulding demand. The alternative solution to reduce the use of cement is by leveraging on natural materials such as baggase ash as a substitution part of cement in the concrete mixtures. Results from test showed that silicte (SiO2) content in bagasse ash was dominant, so that it might be used as a cement substitution to enhance the properties of the concrete. The specimens were tested at 7, 14, 28 and 56 days of treatment to observe the development of bagasse ash concrete with the variation of the ash at 5 % and 10 % from the weight of the cement. The result showed that the higher percentage of bagasse ash would result lower workability. The compressive strength has also decreased from normal concrete at 28 days of the treatment, at 5 % variaton that has a compressive strength at 21,221 MPa and 10% variation has a result at 16.411 MPa. Propertional to compressive test, the flexural test has also decreased from normal concrete, at 5% variation has a flexural strength at 3.60 MPa and at 10 % variation has a result at 3.40 MPa. It was because imperfect of bond between Ca(OH)2 with SiO2. Hence, instead of cement substitute, bagasse ash rolled better as filler in concrete mixtures.
