| 摘 要： | 利用COSMOS/M2.6软件,考虑材料非线性,模拟并分析双向组合楼板的极限承载性能。通过与文献中双向组合楼板足尺试验的对比,验证所建有限元模型的正确性。研究楼板宽高比、长细比等参数的影响;考虑表面平整及剪力钉的影响;研究固定于板底翼板,垂直于波纹方向冷弯钢板厚度及其分布的影响;研究各初始参数对极限承载力,强、弱轴方向应力分布及板挠度的影响。在正常使用极限状态下,进行双向组合楼板的性能研究。与单向组合楼板比较,双向组合楼板承载力及弱轴方向的应力有较大提高。由于使用钢板和剪力钉,组合楼板挠度增大。

| Abstract: | The paper deals with the modeling and analysis of the ultimate behavior of two-way composite slabs.A software package of COSMOS/M 2.6is used.Non-linear material properties are considered.The proposed finite element model is validated by making a comparison with full-scale tests published in literature for one and two-way composite slabs.Many parameters are studied,such as slab aspect ratio and slab slenderness ratio.The effect of embossments flattening is considered.The effect of cold steel straps which are... |
