摘要
对一种新型高强钢筋密肋梁混凝土楼盖的面内刚度进行了试验研究,分析了新型密肋梁楼盖在各个水平荷载作用下对水平力分配,同时分析新型密肋梁楼盖的变形能力。通过试验,验证楼盖刚度面内刚度无限大的假定,高强钢筋对楼盖的面内刚度影响有限,并给出了相应建议,可为新型密肋梁楼盖体系的设计和应用提供参考。
The in-plane stiffness of a new type of high strength steel rebar ribbed beam concrete slab was tested. The horizontal force distribution of the new ribbed beam floor under various horizontal loads was analyzed,and the deformation ability of the new ribbed beam floor was analyzed. The experiments verified that the in-plane stiffness of the floor is infinitely large and the influence of high strength steel rebar on the in-plane stiffness of the floor is limited. Corresponding suggestions were given,providing reference for the design and application of the new ribbed beam floor system.
