摘要
本文对日本阪神地震中的钢结构震害,包括:罕见的两种破坏现象,厚壁柱子脆断和多层房屋中间层整层被摧毁;以及设计不合理和施工、焊接不良;焊接金属热影响区引起的破坏;大跨度空间结构出现的破坏等方面,作了全面简要介绍,并结合震害实况提供了初步分析。特供我国钢结构同行了解与进一步研究时参考。
This paper deseribes the disaster of structural steel in great Hanshen quake in Japan, involving twotypes of strange failure-brittle failure of thick wall tabular columns and total collapse of intermediate storey inmultistorey-as well as failure caused by improper design and unqualified welding and failure in thermal zone atwelded metal, and damage in space structures with large span etc. It gives some insight into stated failure from a practical viewpoint, serving as a reference to structural steel professional.
