基于性能的烟囱抗震设计
|
摘要
基于性能的抗震设计已成为当前抗震研究的热点问题。作为火力发电厂重要构筑物的烟囱,必须满足我国现行《建筑抗震设计规范》的总体抗震设防目标。但是,对于普通单筒钢筋混凝土烟囱主要非结构构件的内衬以及套筒式分段支撑砖内筒烟囱,烟囱规范对其抗震几乎没有要求。通过分析,提出了烟囱内衬和砖内筒的地震作用计算方法以及构造措施。
In recent years,studies on performance-based seismic design are taking out around the researchers of earthquake engineering in the world.As a main structure in a large thermal power plant,the design of the chimney has to be in accord with the seismic fortification criterion in "The Code for Seismic Design of Buildings".There is no clear code for the brick liner of the chimney in the code.The seismic design method and structural measures are proposed.
