RESEARCH ON APPRAISAL AND RETROFITTING MEASURES FOR A FISHERY FACTORY BUILDING SUBJECTED TO FIRE
-
摘要: 对威海市某渔业车间火灾后的结构性能进行检测,运用贯入法检测砌筑砂浆的强度损伤情况,采用取芯方式检测混凝土的强度,通过静载试验检验预应力混凝土双T板残余承载力。根据检测结果及分析,综合评定了结构受损情况,并对圈梁、屋面板、墙体等受损部位给出了相应的修复加固措施,为工程事故的加固处理提供依据。Abstract: The structural performance of a fishery workshop in Weihai was detected after fire.The mortar compressive strength was detected by penetration method,the concrete strength was measured according to the drilling concrete samples,and residual bearing capacity of the prestressed concrete slabs with double T-sections was inspected by static loading test.The retrofitting measures were put forward to damaged bond-beam,roof board and masonry wall respectively,which can provide basis for treating project accidents.
