摘要
目前对现浇钢筋混凝土密肋空腔楼盖结构体系的受力特性、设计理论与方法研究较少,阻碍了其推广应用。通过对竖向均布荷载作用下,2×1空腔构件的楼盖模型试验研究,探索空腔构件、密肋梁两者协同作用的机理和受力特性,同时对该楼盖模型进行有限元计算。结果表明密肋空腔楼盖模型与普通密肋楼盖的破坏特征和受力特点相似,空腔构件与密肋梁有较强的协同工作能力,计算结果与试验结果基本一致。
At present, because of the less research of force characteristics, design theory and method research of the ribbed cast-in-place reinforced concrete floor with cavity structure system, the development of its advantages is hampered. In this article, an experiment research on 2×1 component model of this structural system under vertical uniform load, and the mechanism of cooperative function and force characteristics between the DCKQ cavity components and ribbed beam are discovered. At the same time, a finite element analysis to this model is conducted, the results show that the destroy characteristics and force characteristics of the ribbed cavity floor model are similar to the common floor, and the floor of the cavity components and ribbed beam has a strong ability to work together, and the calculate result are consistent with the experiment basically.
