浅议高烈度软土地区海港工程综合楼抗扭设计

Torsional Design of Administrative Building in Harbor Project Supported on High Intensity Soft Soil Base

海港工程一般地质条件较差,场地类别以Ⅲ、Ⅳ类居多,对抗震较为不利。位于高烈度软土地区的海港工程综合楼抗震设计中,应考虑较差场地土和较大地震影响系数的双重不利影响。本文通过对厦门某海港工程综合楼框架结构抗扭设计的探讨,提出解决扭转周期比超限问题的建议,供海港工程综合楼框架结构设计参考。

In general, the geological condition of harbor engineering field is poor, and most of them belong to class III ＆ IV field, which is bad for earthquake-resistance. The adverse effects of poor field soil and higher seismic influence coefficient should be considered in the seismic design of administrative building of harbor projects supported on high intensity soft soil base. By analyzing the torsion resistance design of administrative building framework in a Xiamen harbor project, the advices are given for solving the overrun problem of torsional cyclic ratio, which will be referred to in similar design.
