摘要
为了更为精确的分析空腹夹层板结构的静动力特性,基于有限元法,建立钢-混凝土空腹夹层板结构的有限元数值模型进行静动力特性分析,同时对比工程计算简化模型和现场试验测试结果,分析结果表明:基于精细化数值模型得到的空腹夹层板静动力特性计算值与试验研究值更为接近,验证了精细化数值模型的合理性和准确性;同时剪力键高度和混凝土板的厚度对空腹夹层板的竖向挠度影响显著,而剪力键高度对空腹夹层板的固有频率影响显著。分析结果对建立精确的空腹夹层板结构模型提供了重要的参考。
In order to simulate the static and dynamic characteristics ofvierendeel sandwich plate structure,this article is based on the fi- nite element method, set up the structure of the steel and concrete vierendeel sandwich plate of fme numerical model, and the static and dy- namic characteristics analysis,and compare the simplified engineering calculation model and field test results,the analysis results show that the vierendeel sandwich plate based on refinement numerical model calculating the static and dynamic characteristics value close to the experimental study on the value and verify the rationality and accuracy of refinement numerical model.Height and the thickness of the concrete slab and shear key had a great effect on the vertical deflection of vierendeel sandwich plate, and the height of shear key has signif- icant effects on the natural frequency of the vierendeel sandwich plate.The results of the analysis to establish a precise vierendeel sandwich plate structure model provides an important reference.
