摘要
钢筋混凝土框架结构遭受火灾后,由于混凝土剥落,有效断面减小,强度降低,构件会出现不同程度的变形.对梁、板、柱分别进行加固后,采用应变测量系统进行检测,并根据数据分析及计算结果确定加固的效果.
After the R.C. frame structure is damaged by fire disaster, the concrete surface of the structure would peel off, the effective section would reduce, the strength would lower, and the members would deforme. After the respective consolidations of the beams, slabs and columns, all those strengthened sections should be fixed with deformeters and an investigation system should be carried out. Basing upon the data analyses and results of calculation for those members, the consolidation efficiency can be ascedtained eventually.
