摘要
在确定了钢材和混凝土的应力－应变关系模型的基础上，应用数值方法计算出了肋筋模板钢－混凝土组合板的荷载－变形关系全过程曲线，并对曲线的特点、考虑底模作用与不考虑底模作用的差异以及各参数对该类组合板力学性能的影响进行了分析．最后，推导了肋筋模板组合板承载力简化计算公式，理论计算结果和简化计算结果及试验结果均吻合。
Based on the determinations of the strain-stress relationships of steel and concrete, the complete load-deflection curve for the ribbed form steel-concrete Composite slabs is analyzed by using of numeric method in this paper. The effect Of the existence of the thin steel sheet as well as the parameters on the behaviors of the slabs were discussed. Simplified formula for the calculation of the bearing capacity of the slab was acquired, the theoretical and calculating results showed a good agreement with those tests.
