摘要
本文作者结合国内一大型工厂工业厂房的抗震加固 ,对框架结构厂房进行了动力有限元计算。在振动台上 ,模拟地震波形 ,对模型粘钢加固和不粘钢原始结构抗震效果进行了比较试验。得出了 :该厂房抗震中构架的薄弱部位 (首坏位置 ) ;在地震波作用下结构破坏的规律和特征 ;粘钢加固后抗震达到的等级
The dynamic FEM has been carried out for a large scale industrial RC building when it is strengthened for earthquake resistance.Experimental results of earthquake resistance of model structures strengthened with adhering steel are compared with that of original model structures under the action of emulated seismic waves on vibration plate.It can be concluded that weak portion of RC frames and failure characteristics under the action of seismic waves and the anti earthquake class of structure after strengthening.
