摘要
为研究影响外包钢-混凝土组合楼盖面内刚度的因素,采用有限元软件ANSYS对外包钢-混凝土组合楼盖和钢-混凝土组合楼盖的面内刚度问题进行了对比分析。结果表明,影响组合楼盖面内刚度的主要因素为楼盖长宽比,组合楼盖混凝土板厚、钢梁尺寸、抗侧构件的布置对其面内刚度有所影响。两种组合楼盖面内刚度随影响因素的变化规律基本一致,外包钢-混凝土组合楼盖面内刚度大于钢-混凝土组合楼盖,空间协同工作的能力较强。
Based on the ANSYS software,the comparative analysis was conducted on the influence of the in-plane stiffness of the U steel-encased concrete composite floor and the steel-concrete composite floor. The results showed that the main factors influencing the in-plane stiffness of composite floor was length-width ratio. Concrete thickness,steel beam size and the location of anti-shear member also had an effect on it. The variation of the in-plane stiffness of both composite floors with affecting factors was basically the same. The in-plane stiffness of the U steel-encased concrete composite floor was higher than that of the steel-concrete composite floor,and space compatibility was stronger.
