A Thin Web Girder Reinforcement Plant Accident Investigation and Analysis of Brittle Fracture

对某厂房薄腹梁主筋脆断事故进行了调查和分析,得出设计规范安全度设置偏低是事故发生的主要原因。既有建筑的安全性评定应按现行规范进行,认真总结经验并吸取事故教训,对建筑结构评定和加固工作具有重要的理论意义和实用价值。

The design of building structures emphasis on the economy too much in China over a period of time,and that lead to low degree of structural safety. In this paper,the workshop of a thin webbed girder main reinforcement brittle fracture accident was investigated and analyzed,and the design specification of safety set low is the main cause of the accident. Further draws the conclusion that the security assessment of existing buildings should be carried out according to the current specification. To summarize and draw lessons from the accident has important theoretical significance and practical value for building structure evaluation and reinforcement.
