Abstract

Abstrak Standard Penetration Test (SPT) dan Cone Penetration Test (CPT) merupakan tes penyelidikan tanah awal yang sering digunakan saat memulai suatu konstruksi. Telah banyak penelitian sebelumnya yang membahas tentang korelasi linier antara nilai SPT dan CPT, namun nilai koefisien korelasinya (R2) cenderung kecil. Jaringan saraf tiruan (JST) merupakan teknik yang dapat memecahkan masalah yang kompleks dan non-linier. Pada penelitian ini akan dilakukan prediksi nilai SPT menggunakan jaringan saraf tiruan pada tanah granular menggunakan algoritma backpropagation. Panelitian ini menggunakan 117 data dari beberapa wilayah di Provinsi Riau. Data masukan yang digunakan berupa nilai tahanan ujung (qc) dan nilai tahanan selimut (fs) dari pengujian CPT dan nilai tekanan overburden efektif (σ'0) serta persentase pasir dan butiran halus. JST dianggap efektif dalam penelitian ini dengan nilai RMSE 3,646, MAE 2,533 dan R2 0,9103 untuk data latih dan RMSE 2,955, MAE 2,190, R2 0,9311 untuk data uji. Selanjutnya model JST ini disebut sebagai NN_Nspt (NC). Kata-kata Kunci: back-propagation, CPT, granular, Jaringan Saraf Tiruan, SPT Abstract The Standard Penetration Test (SPT) and the Cone Penetration Test (CPT) are kinds of Soil Investigation Tests that are used to determine bearing capacity and soil parameters for designing a construction. There are many previous studies had been defined the linear correlation between SPT and CPT values. However, the linear correlation predisposed get correlation coefficient (R2) small. Artificial neural networks (ANN) is an Artificial Intelligence model that can solve complex and non-linear problems. This research aims to conduct SPT value prediction using ANN in granular soil (non-cohesive) with a backpropagation algorithm function. This study used 117 data taken from several provinces on Sumatera island. The variables of input data are taken from CPT, i.e cone resistance (qc)and sleeve resistance (fs), and from the UDS test. The laboratory data were effective overburden pressure (σ‘0), the percentage of sand, and the percentage of fine grain. The best ANN model had a single hidden layer and 40 neurons with RMSE values 3.646, MAE 2.533, and R2 0.9103 for training data and RMSE 2.955, MAE 2.190, R2 0.9311 for testing data. Thus, the best ANN model has been proposed as NN_Nspt (NC). Keywords: Artificial Neuron Network, back-propagation, CPT, granular, SPT

Abstract

Fire is one of the factors causing failure in the reinforce concrete. The surface of the concrete will become black due to significant increase in the temperature. Cracks occur of an imbalance in volume changes exist between cement paste and aggregate. This study aims to analyze the effect of the rate of changes in temperature on the RC during the fire. The method used is to analyze the rate of changes in temperature according to ASTM E- 119 standard. Analysis was conducted by using finite element software, LUSAS v.16. The column specimen used in this study had rectangular ratio of 350 mm × 600 mm with the length of 4000 mm. The amount of longitudinal bars was 10D19, while the yield strength of bars and the concrete strength was 400 MPa and 45 MPa, respectively. The column element burned with a duration of 4 hours. The results showed there was a difference in term of temperature change’s rate between LUSAS v.16 and manual calculation was 3,7%. This research can be used as a reference on designing fireproof buildings so as to prevent building collapse during a fire.Keywords : ASTM E-119, rate of temperature, LUSAS v.16

Abstract

Beam as one of structural elements is generally designed to exhibit ductile behavior before failure. The ductility of the whole structure is affected by the characteristic of its structural elements. The ductility of reinforced concrete (RC) beam could be measured by curvature ductility parameter. Curvature ductility is defined as the ratio between the beam curvature at ultimate state and yielding state. The ductility curvature value can be calculated based on the moment-curvature curve. One of the structural analysis softwares that can be used to produce the moment-curvature relationship curve is Response2000. This research aims to analyze the impact of varying the reinforced concrete beam characteristics to the ductility of the beam which is performed using Response2000 software to model the singly-reinforced concrete beam. By varying the concrete compressive strength, reinforcing bar (rebar) strength and diameter, reinforcement ratio, and concrete section (width and depth of concrete), 38 models of beam were generated. Based on the analysis results, it was observed that the increment of concrete compressive strength and effective depth increases curvature ductility, whereas the increment of rebar strength and reinforcing ratio reduces curvature ductility. Manual calculations on the curvature ductility showed that the output produced by Response2000 only the average difference from the manual calculations is 15,361%. This indicates that Response2000 is a reliable tool to calculate the curvature ductility of reinforced concrete beam.Keywords: ductility, reinforced concrete, moment, curvature, Response2000

Abstract

Irregularity of building structure often emerges due to the room configurations to meet the architectural requirements. In irregular building, eccentricity exists between its center of mass and its center of rotation. The eccentricity generates torsion, which usually leads to the placement of rigid structural elements to increase the rotational stiffness of the building structure. One of the options to increase the building structure stiffness is by placing shear walls in the building. This research aims to analyze the impact of structure irregularity to the eccentricity of building structure and the effectiveness of various shear wall configurations to resist earthquake load. Building to be analyzed is Aulia Hospital buildings with earthquake load time history. Modeling is done with the help of the finite element program. The model will be made to the building without shear wall, existing and modification. The modified model is a model with a different positioning of the existing shear wall based parameter eccentricity. The analysis produced fundamental period and maximum displacement of the building as output. The fundamental period was calculated equal to 3.102 second for the building without shear wall; 2.087 second for the existing building; 2.011 second for Modification 1 Building; and 1.756 second for Modification 2 Building. The maximum displacement in X direction was calculated equal to 246.01 mm for the building without shear wall; 114.1 mm for the existing building; 107.24 mm for Modification 1 Building; and 102.07 mm for Modification 2 Building. Whereas the maximum displacement in Y direction was calculated equal to 230.37 mm for the building without shear wall; 169.7 mm for the existing building; 156.5 mm for Modification 1 Building; and 97.7 mm for Modification 2 Building. Based on the analysis results, it can be concluded that Modification 2 is the most effective model to resist earthquake loading.Keywords: Shear wall, Irregular Building, Eccentricity, Displacement

Abstract

Each building have to be designed so that the building is safe from earthquake load. The purpose of the study is to analyze the drift ratio, reaction force and structural performance at steel structures by using Direct Analysis Method (DAM) and Effective Length Method (ELM). the building structure is analyzed for earthquake loads based on the 2010 earthquake map and 2017 earthquake map. In the study, a 10-story building with a length of x 4 m and y 5 m, a ground floor height of 4,5 m and floors 1-10 is 3,5 m. The total building height is 36 m using IWF 478,447.60.60 and IWF beams 406,403.24.26. The structural system uses an open system without bracing. The structural analysis uses SAP2000 software. The results of the analysis for the DAM and ELM methods show that the deviation between levels is by the provisions of RSNI3 1726 201X, which is less than the deviation between permit levels of 0,0692 m for the ground floor and 0,0538 m for floors 1-10. Structural performance using pushover analysis based on FEMA 356, for the DAM and ELM methods results in an IO (Immediate Occupancy) level of performance with a drift value below 0,7%. Structural analysis found that the force in the DAM method was 1,4% smaller than the ELM method. This is because in the DAM method there is an increase in notional load at the nodal point at all levels. Analysis of the force on the 2017 earthquake map is smaller by 9,8% compared to the 2010 earthquake map. This is due to the acceleration value of the response spectrum on the 2017 map for S1 and Ss by 0,299 and 0,236, while for the 2010 earthquake map for S1 and Ss by 0,441 and 0,274.Keywords: Portal structure of Steel, performance, moment, stress ratio, earthquake hazard map 2017, earthquake hazard map 2010
