摘要：

针对物流仓储荷载大、净空高的需求,带肋叠合板为理想的楼板形式. 采用有限元软件数值模拟对直通型底部加劲肋叠合板与加劲肋端部收起叠合板的承载力和钢筋应变进行分析,并验证端部收起设计的合理性. 结果表明:2 种模型的荷载⁃位移曲线均呈 3 阶段发展特征,底部加劲肋直通设计在受力性能上更具合理性.

In view of the demand of large logistics storage load and high clearance, ribbed composite slabis an ideal floor form. The finite element software numerical simulation is used to analyze the bearingcapacity and steel bar strain of the straight⁃through bottom stiffened rib composite plate and the stiffenedrib end retracted composite plate, and the rationality of the end retracted design is verified. The resultsshow that the load⁃displacement curves of the two models show three⁃stage development characteristics.The bottom stiffener straight⁃through design is more reasonable in mechanical performance.
