接触爆炸作用下双波纹钢板混凝土组合板抗爆性能数值研究
Numerical Study on Blast Resistance of Concrete-Infilled Double Steel Corrugated-Plate Wallboard Under Contact Explosion
摘要
Abstract
The concrete-infilled double steel corrugated-plate wallboard(CDCPW)has greater out-of-plane bending stiffness,compressive capacity and shear capacity,and has a wide potential application in super high-rise buildings,offshore platforms and other structures compared with the ordinary concrete-infilled double-steel plate wallboard(CDPW).The finite element model of the CDCPW was established first.The failure mode and explosion response of the CDCPW were numerically analyzed by ANSYS/LS-DYNA nonlinear software,the accuracy of the numerical analysis method was verified by comparing with the contact explosion test of the CDPW.The influence laws of corrugated alignment,corrugated depth and corrugated density on the blast resistance of the CDCPW were parametrically analyzed.The results show that the blast resistance of the CDCPW under the same contact explosion is better than that of the CDPW,and the contact explosion resistance of composite plate can be improved by using special shaped corrugated steel plates(the upper is raised and the lower is sunken)and increasing corrugated depth and density.关键词
