Novel Approach on Performance-Based Aseismic Design Based on FEMA Requirements

Building codes related with performance-based aseismic design contain some performance goals and levels to increase the resistance of the structure to the earthquake effect. In the finite element nonlinear -pushover analysis plastic hinge formation is one of the essential data analyzed by researchers to distinguish the location of the building where larger potential damage may happen. If the number of plastic hinges in the structure is increased, the total capacity of the structure will increase proportionally. On this point of view reaching the maximum number of plastic hinges must be added as the new performance goal or level to the performance-based aseismic design codes, which will dial to the highest ultimate load of the structure. In this arrangement, a number of n 1 plastic hinge can be formed to achieve the complete collapse of a known n th hyperstatic plane frame system. This paper presents an assessment of the aseismic performance of structure based on adding to the existing mentioned methods a new performance goal. On example of five-story plane frame system based on FEMA 440 methods, assessment results indicate that with decreasing the stiffness of the beams at the above stories the number of plastic hinges increased, and the total capacity of the frame was increased by 7.41, and 7.87 , respectively.
