000010390 520__ $$2eng$$aTremendous energy demand exists usually for impulsive earthquake records close to active fault zones, so it is essential to check the validity of actual seismic design codes from energy concept. By introducing of the spectrum velocity amplification factor, equivalent energy compatible with major Chinese and U.S.A. seismic codes was derived, and the extent of effective period was extracted by 214 near-fault records. The recommended energy input design spectrum (EIDS) applicable to 0~15km fault zone was quoted to check the validity of these seismic codes. Comparison analysis shows that GB50011-2001 code can just match the energy amplification effect of near-fault earthquake to a certain extent only under seldomly occurred earthquake with fortification intensity of 9 degree for soilⅡ,Ⅲ and Ⅳ, which means the impact of near-fault effect is not embodied in the current code acceleration spectrum. It is necessary to adjust the spectral control parameters. On the contrary, the energy spectrum compatible with UBC97 code can match well with the proposed energy input spectrum apart from the soil of hard rock (SA). Accordingly, the correctness of proposed energy input design spectra in this paper got also certified by another way.
