某展馆钢网架风灾后安全性检测鉴定

Safety Inspection and Identification of the Steel Gird Frame of an Exhibition Hall after Storm

对风灾后钢网架结构的科学检测与鉴定,是灾后主体结构能否被合理加固修复的关键因素。本文以某展馆为例,对该展馆进行了风灾后的现场查勘及检测,根据委托方提供的资料和现场的检测结果对主体结构进行内力计算和分析,对风灾后结构的安全性作出正确的检测鉴定评估,并对灾后构件受损产生的原因进行了分析。

The scientific inspection and identification of the steel grid structure after storm are the key factors of whether the main structure can be properly reinforced and repaired. In this paper, an exhibition hall is employed as an example, where the on-site survey and inspection have carried out. According to the information provided by the entrusting party and the in-situ inspection results, the internal force in the main structure is calculated and ana- lyzed, based on which the structural safety after storm is evaluated. Meanwhile, the causes accounting for the dam- age of the components have been also analyzed.
