爆炸荷载下粘钢加固混凝土结构局部破坏机理

Analysis of Local Failure Mechanism of Composite Steel Plate-RC Structure Under Explosive Load

将介质视为流体弹塑性体系,采用一维弹塑性应变波理论分析钢板防震塌破坏机理,圆满地解释了有无钢板加固混凝土在爆炸荷载下的实验现象;并提出确定钢板厚度的计算方法,与实验结果吻合较好。

The material is considered as fluid elasto-plastic system. Theory on elasto-plastic strain wave is applied, which explains successfully the test results of the concrete with or without bonded steel plate under blast load. The method used to detemaine the thickness of steel plate is proposed. It is shown that theory analysis is in good agreement with experimental results.
