摘　　要：为深入研究钢筋桁架楼板的受力性能,设计了足尺寸楼板试验。通过分析试验结果,得到底部压型钢板对钢筋桁架楼板承载力的影响。采用有效惯性矩法计算钢筋桁架楼板的正截面承载力的理论值,经与实测值比较,发现有效惯性矩法所算得的数值与试验值更为接近。提出可供参考的钢筋桁架楼板正截面受弯承载力计算公式,并给出相关修正系数。In order to make a deep research on the structural behavior of steel bar truss slab,we have designed a full-scale slab experiment.The influence pattern was obtained through the analysis of the test results. And the steel slabs have an effect on load-carrying capacity of steel bar truss slab.Effective inertia method was used to calculate the ultimate load.By comparing with the test results,we find that the calculated value of effective inertia method is closer to the test result than that of static equilibrium method.The formula of load. carrying capacity is advanced for future reference and the modified factor is also ~iven.
