本文介绍了6度区为什么抗震、有哪些震害、抗震鉴定的主要内容及抗震加固投资分析。抗震鉴定的主要原则:一是不进行抗震验算,只对抗震构造措施进行鉴定。二是把建(构)筑物分为三类:一类指石油企业生命线系统的重要建(构)筑物,其构造措施按7度进行鉴定;二类指一般性建(构)筑物,按6度进行鉴定;三类指次要建(构)筑物,不作抗震鉴定。
This article describes why the 6 degree zone earthquake, which earthquake damage, the main content of seismic evaluation and analysis of seismic reinforcement investment. The main principles of earthquake resistance appraisal are as follows: First, earthquake proofing calculations are not carried out, and only measures against earthquakes are identified. The second is to classify buildings (buildings) into three categories: one refers to important structures (structures) of the lifeline system of oil companies, whose structural measures are identified at 7 degrees, and the second type refers to general structures (structures). , According to 6 degrees for identification; Three types of secondary construction (structure), not for seismic evaluation.
