住宅楼火灾后综合加固设计
|
摘要
某工程地下2层,地上8层,地下室和地上1, 2层为框架结构,地上3层以上为砖混结构。发生火灾后,根据鉴定报告严重烧伤区域的柱混凝土不满足原设计强度要求,需对火灾影响区域的主体结构进行加固设计,经采用拆除预制板卸载后再粘贴碳纤维加固梁和外粘型钢加固柱等措施,综合加固效果良好。
A project has 2 underground floors, 8 floors above ground, 1 and 2 floors in the basement and above ground, and a brick-concrete structure above 3 floors above ground. After the fire occurs,according to the identification report, the column concrete in the severely burned area does not meet the original design strength requirements. The main structure of the fire affected area needs to be reinforced.After the prefabricated plate is removed, the carbon fiber reinforced beam and the outer bonded steel reinforced column are attached. And other measures, the comprehensive reinforcement effect is good.
