Comparison Of The Earthquake Relevant Provisions Of Chinese Code For Secimic Design Of Buildings And American Building Codes

The establishment of the Chinese Code for Seismic Design of Buildings (it calls Code 01 later) has taken many references and lessons of the international Building Code. This paper sums up the differences between both Codes, by carefully comparing the seismic provisions and measures of the Chinese Code with IBC2000,IBC2003,UBC97 and ACI318M-05. It illustrates the improvements of the Code(01), which are good for.the recension.Complete seismic design of buildings includes design principles, earthquake effect calculations and structural seismic measures. The paper does some researches on both Codes, By contrast with the seismic design principles, the regulations of soil profile types, seismic fault and sand(silt) liquefaction, the calculation methods of earthquake effect and the seismic measures of both Codes.We find that: the seismic fortification object of the Code(01) is much clearer than the foreign's, but the seismic design method is not corresponsive to R–μPrinciple, which is not as strict as the foreign Code; the ground soil classification of the Code(01) is much rougher while the regulation of sand(silt) liquefaction is much more conservative than the international ones; the seismic requirement of Code(01) is lower in middle and low intensities but much higher in high ones; the requisition of the Code(01) is simply the same as the international one when the seismic intensity is NO.1. if in orther intensities, the Code(01)'s is much lower.On foundation of analysises and contrasts, the paper gives advices of satisfying our Seismic Design Codes and brings up more questions that need to answer on the orther day, which have deep meanings both on engineering and theorical study of the further work.
