摘要
本文通过工程实例,探讨石结构钢木屋架该类空旷结构如何通过分区、整体受力计算分析的方法进行结构安全及抗震可靠性鉴定,鉴定过程须关注石结构采用何种砌筑方式、钢木屋架要注意节点、支撑、连接构造及屋架布置情况,并得出年限较久的该类结构主要存在钢木屋架布置不合理,整体性差的特点,为类似工程的抗震鉴定工作提供一些参考。
With engineering examples, this paper explored the safty and earthquake -resistance reliability appraisal method of the span structure,as stone - built structures steel - wood roof truss, by section splitting, mechanics behaviors analysis. The appraisal process should focus on the masonry of stone - built structures, the nodes,braces,connection constructors and disposition of steel - wood roof truss. The same type structures with long age has features as unreasona- ble disposition and poor structural integrity of steel - wood roof truss was concluded. It can provided some references of earthquake - resistance authentication for similar engineerings.
