摘要/Abstract

摘要： 为研究双钢板混凝土组合(SC)板的抗撞性能，本文采用ABAQUS建立了SC板在落锤撞击下的有限元模型，并通过已有SC板落锤撞击试验结果验证了数值模型的准确性.基于此，重点研究了构件钢板含钢率、撞击高度、材料强度、边界条件与撞击物形状等参数对该类构件动力响应的影响；最后利用简化能量守恒法计算了SC板跨中最大挠度.结果表明:在本研究参数分析范围内，钢板含钢率、撞击高度、撞击物形状与边界条件对该类构件动力响应影响较大，且当钢板含钢率大于4%时影响更加明显.建议的简化能量守恒法可有效预测SC板在撞击荷载作用下的跨中最大挠度.

Abstract: In order to study the impact-resistant performance of double-skin steel-concrete composite(SC)panel， the ABAQUS software was utilized to establish the finite element(FE)models of SC panel subjected to drop hammer impact. The accuracy of numerical models was verified by comparing the FE simulations with the test results. Based on the validated models， the influences of steel plate ratio， impact height， material strength， boundary condition and indenter shape on the dynamic responses of SC specimen were revealed. Finally， the energy method was employed to calculate the maximum mid-span deflection of SC panel. The results indicate that steel plate ratio， impact height， indenter shape and boundary condition present significant effects on the dynamic response within the parameter range of this work， and the effects are more obvious when the steel plate ratio exceeds 4%. The theoretical calculation method used in this study can reasonably predict the maximum mid-span deflection of SC panel under impact loading.

Key words: double-skin steel-concrete composite panel; impact; finite element analysis; dynamic response; theoretical calculation
