建筑抗震设计中的小、中、大震烈度研究

INTENSITY RESEARCH OF SMALL, MEDIUM AND LARGE EARTHQUAKES IN ASEISMIC BUILDING DESIGN

作者以地震学的观点，在研究地震复发周期与震级一频度关系式中的ｂ值的基础上，研究了建筑抗震设计中的小、中、大震之间的烈度差值。指出该烈度差值只与ｂ值有关，因此是因地而异的。建议今后修改规范时考虑。

According to the viewpoint of seismology and research of b value in formula for earthquake reoccurrence period and magnitude-frequency the authors research intensity difference values of small, medium and large earthquakes in aseimic building design and suggest that the intensity difference is only related to b value and so it is changed with site, which should be considered in the revision of aseismic building code in future.
