摘要
北京时间2015年4月25日尼泊尔博克拉附近发生了8.1级地震,作为中国赴尼泊尔地震灾害评估组成员,作者对尼泊尔境内各类工程结构的震害进行了深入考察。自建钢筋混凝土框架结构是尼泊尔各阶层民众广泛认同并大量建造的房屋结构形式之一,在此次地震及强余震中遭受了不同程度破坏。基于尼泊尔8.1级地震及其余震的现场震害调查资料,本文总结了其抗震构造特点;分析了其震害特征和震害原因;指出了其在结构设计和施工中主要存在的问题;针对自建钢筋混凝土框架结构存在的问题给出了建议。
An earthquake measured M_s 8.1 occurred near the Nepal Pokhara on April 25,2015(Beijing time).As a member of China to Nepal disaster assessment team,the author conducted thorough investigation about the earthquake damage of all kinds of engineering structure in Nepal.Self—built reinforced concrete frame structure which is widely accepted by the people at all levels in Nepal and is one of the building structure forms which are widely built suffered damage by varying degrees in the strong earthquake and aftershocks.Based on the seismic damage investigation date of the earthquake and its aftershocks,the characteristics of aseismic construction are summed up,the damage characteristics and the reasons of its destruction are analyzed.The main problems in the design and construction of the structure are pointed out.The advices on the existing problem of self—built reinforced concrete frame structures are given.
