A Brief Introduction of FEMA P695—Quantification of Building Seismic Performance Factors

In current specifications,evaluation of collapse probability for buildings in severe earthquakes has not been well solved all over the world.Based on the current American seismic design code of buildings,FEMA P695 proposes a guideline to calibrate the key design parameters to ensure the collapse probability of buildings in severe earthquakes not exceeding an acceptable value.In this paper,theoretical principle of the current American seismic design code of buildings and its relationship with FEMA P695 are introduced briefly.The method,process,key details and theoretical concept of FEMA P695 are discussed to provide an outlook about the development of the seismic reliability design for buildings in the United States.
