摘要

采用LS-DYNA建立了冲击作用下单钢板混凝土组合板（Half-SC板）的有限元模型，根据现有试验结果验证了模型的准确性，并进一步分析了冲击物质量、冲击速度和钢板厚度对Half-SC板位移响应的影响规律。在此基础上，推导了Half-SC板的抗力和刚度计算式，提出了Half-SC板的抗力函数，并建立了计算Half-SC板位移响应的等效单自由度模型。研究结果表明：Half-SC板在冲击作用下的破坏过程可分为弹性受力阶段，混凝土冲切开裂阶段，水平钢筋断裂阶段；冲击速度对Half-SC板位移响应的影响最大，冲击物质量次之，钢板厚度的影响最小；所提出的等效单自由度模型能够很好地预测Half-SC板的位移时程。

Abstract

A finite element model of half steel plate-concrete composite slabs (Half-SC slabs) under impact action was established using LS-DYNA. The accuracy of the model was verified based on the available test results. The effects of the impactor mass, the impact velocity, and the steel plate thickness on the displacement response of Half-SC slabs were further analyzed. On this basis, the resistance and stiffness equations of the Half-SC slabs were derived. The resistance function of the Half-SC slabs was proposed. Thus, an equivalent single-degree-of-freedom model for calculating the displacement response of the Half-SC slabs was established. The results show that the damage process of Half-SC slabs under impact can be divided into three stages such as the elastic stage, the concrete cracking stage, and the horizontal reinforcement fracture stage. The impact velocity has the greatest influence on the displacement response of the Half-SC slabs, followed by the impactor mass and the steel plate thickness. The proposed equivalent single degree of freedom model can accurately predict the displacement time histories of Half-SC slabs.
