Abstract

This study evaluated concentric and eccentric braced-frame subjected to El Centro and Pasadena earthquake. The parameters examined were natural periods, story drift, hysteresis loop, element's and structure's ductility. The structures are 1 2-story steel frames with 4 (four) different bracing configurations, such as: diagonal concentric bracing (A1), inverted V concentric bracing (A2), diagonal eccentric bracing (B1) and inverted V eccentric bracing (B2). Structural Analysis Program (SAP 2000) Version 7.42 and Microsoft Excel had been used as analytical aids. The methodology in this study consisted of design stage and analysis of structure behavior. In order to examine structures behavior, the structures were analyzed using the same section properties. The result showed that BI frame has the largest natural period of 0,423 second and the lowest natural period is A2 frame of 0,362 second. Steel frame B2 has largest drift due to El Centro and Pasadena earthquake. This seismic load resulted in elastic behavior for all steel frame under consideration s0 as the structure ductility () —1. The same result of unit ductility was obtained for all elements since plastic hinge had not been developed.

Abstract

The Force Based Design (FBD) and the Direct Displacement-Based Design (DDBD) are methods for designing seismic-resistant buildings. Building structures designed, are expected to be suitable with the purpose and usefulness of a building. For this reason, this study compares the performance of dual system structures using the DDBD and FBD methods that aim to prove better performance with consideration of safety against users during an earthquake. This research method uses design analysis method to compare the value of the base shear force, reinforcement ratio, and performance level using software for static nonlinear pushover analysis. The results showed the value of the base shear force x direction of the DDBD method was 17.57% smaller than the FBD method, whereas for the y direction the DDBD value was greater than 9.38% of the FBD. The value of the reinforcement ratio of the beam, column and shear wall results is greater DDBD than FBD. The actual drift of the DDBD and FBD methods is slightly different. So that both are at the same level of performance, namely damage control. The performance level has not reached the performance target of life safety design in DDBD, but the structure has met the level performance requirements for offices.

Abstract

High-rise buildings are at risk of collapse due to the earthquake. One method for analyzing earthquake loads is Pushover. Pushover is a non-linear static analysis to determine the behavior of a building collapse. This research was conducted to determine the performance of the setback building with a soft first story due to the earthquake based on the results of the pushover analysis curve. The structure is modeled as a 2-dimensional portal with a form of structural irregularity (setback with the soft first story) which consists of 2 structural models with different setback area ratios. The results of the analysis of this study indicate that the maximum shear force based on capacity curves in type 1 and type 2 buildings are 50260549.81 N and 53560488.63 N. Buildings with smaller setback area ratios, i.e., type 2 buildings have displacement, story drift, and base shear are more significant than type 1 buildings. Performance of type 1 and Type 2 building structures that refer to ATC-40 and FEMA 356 is at the Damage Control level.

Abstract

In designing seismic-resistant buildings, it is commonly used Forced-Based Design method. The concept of the Force-Based Design (FBD) method is based on an elastic analysis of the structure and indirectly shows the performance level of the structure towards the effects of the seismic forces. Therefore, it is required an approach that capable of analyzing and evaluating the performance of the inelastic structural response; it is called Performance-Based Design method. This paper uses two methods of Performance-Based Design, there are Direct Displacement-Based Design and Capacity Spectrum Method, by using pushover analysis. The objectives of the research are to analyze and compare the performance level of the building in inelastic condition by using these two methods. The structural model reinforced concrete special moment frames. Seismic design code that used in this study is SNI 1726:2012. The reviewed parameter values are displacement and story drift values, estimated plastic hinge response, and performance level of the building from two methods. As the results, all the parameter values of DDBD analysis are more significant than CSM. DDBD produces the drift and displacement values of 0.668 m with the rebar ratio is more significant than 1.00. While, the CSM produces the drift and displacement values of 0.501 m with the rebar ratio of 1.00. The failure mechanism of both methods indicates the strong column weak beam where the beams should fail before the columns. The structure performance level which refers to ATC-40 indicate that both DDBD method and CSM method are in Damage Control level despite displacement target of the two methods are different which is DDBD produces displacement target of 0.376 m while CSM produces the value of 0.345 m.

Abstract

In precast concrete, a connection is needed to unite the components so that they become a whole unified structure. This study aims to determine the reinforcement strength and length of reinforcement in precast concrete connections. To paste reinforcement into precast concrete, giving additional material in the form of grouting which is called sika grout 215 and functions as an adhesive is necessary. Pullout testing is carried out in the laboratory, and its simulation by modeling uses the finite element method based software. This research is divided into 2 phases. The first phase is making specimen to examine the bond strength between the concrete and reinforcement that has been given sika grout 215. So monolithic specimen is made as a comparison. The result of the bond strength of the monolithic test specimen is 6.24 MPa, and the sika grout 215 category is 6.52 MPa. From the experimental results in the laboratory with modeling, it is obtained the bond strength ratio of 0.94. The length of development (ld) based on the results of the testing phase I of 200 mm. The second phase is examining the damage pattern due to the stress that occurred. Specimens are made into 4 categories, namely modeling developments with the length of 120 mm (<40% ld), with the length of 160 mm (<20% ld), with length of 200 mm (= ld), and with the length of 260 mm (> 30% ld) both for monoliths and sika grout 215. The damage pattern, which is in the form of yielding and breaking reinforcement as the result of the pullout experiment in the laboratory shows not much different from the result of simulation using the software.

Abstract

Abstract One of the requirements in reinforced concrete structures is the existence of bonding between reinforcement and concrete, so that if the concrete structure of the given load will not slip between reinforcing steel and concrete, with a condition for disbursement length and diameter sufficient reinforcement. This research was conducted with laboratory experimental methods, this study used threaded steel bars 10 mm in diameter grown on cylindrical concrete specimens with a length variation of normal quality distribution of 100 mm and 200 mm, and for thickness variation Sikadur® 31 CF Normal used a thickness variation mm, 2 mm, 3 mm. Each specimen is tested with a method of "bond, a pull-out test". Based on the results obtained from voltage variations thick adhesive Sikadur® 31 CF Normal, with thick sticky voltage Sikadur®31 CF Normal 2 mm produces voltage optimium closely with the value of 8.412 MPa,the adhesive stresses are found for the distribution of the required length of 182.860 mm for thickness variation Sikadur® 31 CF Normal 1 mm, 97.586 mm for thickness variation Sikadur® 31 CF Normal 2 mm, while for thickness variation Sikadur® 31 CF Normal 3 mm can not be calculated and analyzed the test results because of the "bond, a pull-out" no reinforcing steelreaches the yield condition, caused by broken concrete and reinforcing steel cylinder apart before reaching the yield condition. Then the length distribution obtained by the above formula Park & Paulay compared with the length distribution of article 14.2 of SNI 30-2847-2002 obtained epoxy ratio of 2:13 for the thickness of 2 mm with a planting of 100 mm. In the epoxy thickness 1 mm with 200 mm obtained planting 2:7 ratio, and the planting of monoliths obtained 2:5 ratio. Bold use of Sikadur® 31 CF Normal apparently affect the pattern of damage to the concrete and steel. When planting steel bars are too short we need a thicker epoxy, planting reinforcement 100 mm with a thickness of 3 mm epoxy. When planting longer needed a thinner epoxy, the planting of 200 mm reinforced epoxy with a thickness of 1 mm. Based on the pattern of damage that occurs, the thickness of epoxy should consider the quality of concrete used to prevent the destruction of the concrete. Keyword: grouting thickness, development length, bond stress.

Abstract

Abstract Design on building a less mature may result in failure of the building functions. It can be seen from the emergence of cracks in structural elements. To handle these problems, to prevent any malfunction or possible collapse of the building, it is necessary to strengthen or repair the structural elements that are considered damaged. Damage to the structure elements can be seen from the comparison between the existing calculation of structural elements with ideal calculations buildings. If the ideal calculation is greater than the existing calculation of the structural elements considered necessary improvements. There are several options for strengthening methods. But the selection of methods must be based on the needs, circumstances and budget for strengthening the field itself. In this project the planners combine two methods for strengthening, the concrete jacketing and inject column. In each of these methods has advantages and disadvantages of each is conditioned by the field. Because of this, then inject column be the first choice at this stage of the selection method, this is because the advantages of this method can reduce the force in the received by beam. If this method can not be done due to limited field conditions will be the second selection method that is concrete jacketing. In this method of structural elements can add the capacity of strength to restrain load factored. Until the choosing of the appropriate method. Keyword: concrete strengthening, concrete jacketing, inject column.
