摘　　要：目的确定压型钢板-混凝土组合板的极限承载力,并提出较准确的有限元分析模型.方法采用几何平衡关系的力平衡方法获得闭口型压型钢板-混凝土组合板的纵向剪切强度和端部滑移的关系,进行有限元分析.将有限元分析结果与试验值进行对比.结果剪跨比较短的试件在抗弯刚度上有一定的误差,但极限承载力吻合很好(误差最大不超过7.3%).结论随剪跨比的增加,最大纵向剪切强度减小;提出的力平衡方法有限元计算模型可应用于闭口型组合板类的有限元分析中,此计算模型可以比较精确的确定压型钢板-混凝土组合板的极限承载力.The behavior of composite slab with steel deck is extremely intricate, so it bothers engineers to de- fine a loading capacity. To decide a loading capacity of newly designed composite slab, it needs a great num- ber of experimental test specimens. Therefore, it is necessary to develop the affective and simplified finite el- ement analysis method. In this research, a finite element analysis model that using force equilibrium method in previous research was introduced, and its result was compared with tested data. As a result, load carrying capacities by both finite element analysis and experimental test are well matched; however, there are also small errors in deflection of slender composite slabs.
