New Design Criteria in Performance Based Earthquake Engineering
In order to increase the resistance of the building against earthquake effect in performance based design, the main objective is to select a performance target as design criteria and to design the structure to meet this target. In the nonlinear analysis with finite element method, the formation of the plastic hinge can lead to great potential damage to the building, so they are one of the basic data to determine the state of the building. Accordingly, if the number of plastic hinges in the building is increased, the total horizontal load carrying capacity of the structure increases proportionally. Theoretically, when the structure of plane frame bearing system reaches a plus value of the degree of indeterminacy of the structure, the structure will reach the capacity to bear the largest final horizontal load. For this reason, in this study, in addition to the current design criteria in the relevant codes, it is aimed to increase the structure to the maximum load carrying capacity level by adding the new criterion “to increase the number of plastic hinges to be formed in the structure as much as possible and to keep the structure below its targeted performance by code”. As a result of the studies conducted according to the new performance criteria presented, the load bearing capacity of the frame bearing system has increased by 50 compared to the current code results.
