Design Suggestion on Seismic Fortification Criterion of C Types Building Structures for Design Working Life Below 50 Years/Chen Caibao (China Architecture Design ＆ Research Group, Beijing 100044, China)

Abstract:The four classes(degree 6,7,8,9) of seismic fortification intensity in code seismic design of buildings GB50011—2001 are separated 26 classes, and five for degree 6 of them,ten for degree 7 of them are increased by 0.01g, ten for degree 8 of them are increased by 0.02g. The relation between the clasees and design working life of structure below 50 years for places in the defferent seismic fortification intensitys is set up, which can be used for seismic appraiser and design of C type’s building structures below 50 years by design working life.

Keywords:design working; life seismic fortification criterion; below 50 years
