Collapse Reason Analysis of a Steel Truss Building under Snow Disaster

摘要

This paper analyzes the reason of a steel truss building which collapsed under a snow disaster. Firstly, the investigation and inspection in site are introduced. Secondly, based on the on site work, such as the property of the metal materials and the quality of the welding joint, the status of the structure is comprehensively determined. Thirdly, through calculation with the former results, the reason of the collapse accident is obtained. Finally, some related suggestions are proposed for the design and construction of this kind of structure.
