摘要：
In the seismic performance of reinforced concrete (RC) frame structure, the slab effect has a strong influence on the analysis results. The traditional solution method is to use the solid element to build the integral model, which needs a complicated model and costs a lot of computational time. For improving the efficiency of modeling and analysis, plastic hinge method was proposed. Plastic hinge method used the frame element to build the model and simulate the slab effect by modifying the plastic hinge property. The modified plastic hinge property data were calculated from the combined models of beam components and slab components. Plastic hinge method was applied to estimate the seismic performance of a two-story typical RC frame. The results show that compared with the traditional method, plastic hinge method is an effective method of the slab effect simulation. © 2017, Central South University Press. All right reserved.
