Abstract

Buildings should be designed to withstand an earthquake based on earthquake planning standard. However, the references used in the regulation could not show building performance to the actual earthquake directly. Therefore, it required an assessment of the existing buildings, in order to evaluate their vulnerability (structural performance level).This study discussed the vulnerability assessment of reinforced concrete buildings from the analysis of the relationship between base shear and displacement, and any failure that occurred.The first step of the evaluation was analyzed the seismic loads with Static Nonlinear (Pushover) Analysis using SAP2000 software. The pushover analysis results showed the level of damage to assessthe building damages. This research was based on SNI 03-1726-2002, Federal Emergency Management Agency (FEMA) 273/356, FEMA 440, and the Applied Technology Council (ATC)-40. Displacement values obtained from Pushover Analysis compared with the field studies. From the pushover analysis, the results obtained the capacity curve showing the relationships between the base shearsand the displacements, reviewed at each elastic conditions, ultimate, plastic and collapse. The numerical results turned out to be closed to the performance level of the structure in the field. Thus the analysis can be used as a reference on an assessment level of performance and behavior of the existing structure as well as the vulnerability of the structure.

Abstract

Generally the concrete behavior can be observed by the experimental analysis. However, since the computer technology development has been increased rapidly, the computer simulations are also able to represent the detail behavior of concrete. This paper presents the modeling response of concrete material subjected to biaxial loading using finite element method software based. The plain concrete plates with dimensions 200mm x 200mm x 50mm and 150mm x 150mm x 50mm are analyzed using various combinations of biaxial loading. The results of the biaxial load combinations are covering the three non-linear regions of compression–compression, compression–tension, and tension–tension. The results of finite element analysis are also show good agreement to the experimental results that been taken from the previous study. The comparison results the difference between analytical and experimental study are less than 5%. Therefore, the concrete material model based on this finite element method software can be used to simulate the responses in the real condition.
