摘要:
为了研究现浇混凝土空心楼盖结构的受力特性,应用通用有限元分析软件ANSYS,分析了该类型楼盖结构与实心板楼盖结构的受力差异,得出了空心楼盖结构的应力分布特点; 对现浇空心楼盖结构和实心楼盖结构的应力分布图和位移分布图进行了比较,总结了现浇空心楼盖结构的内力分布规律; 在此基础上,进一步分析了现浇空心楼盖的柱端抗冲切特性。结果表明:现浇空心楼盖的柱端抗冲切承载力与柱边裂缝穿过空心体的数量有密切联系,分析结果将对现浇空心楼盖结构设计方法的进一步改进提供一定的理论依据。
Abstract:
In order to study the force resistance properties of cast-in-situ hollow concrete floor structure, the current FEM software, ANSYS, was adopted to analyze the difference of force resistance between this floor structure and solid slab. Some stress distribution traits of this floor structure were made, and the differences of stress and displacement distribution figures between these slabs were compared so that some laws of internal force distribution of the hollow floor system were summarized. Based on these results, the characteristic of punching shear resistance was further analyzed. The results show that the crack pattern is taken into consideration; it can be realized that the force of the punching shear resistance must be related closely to the number of hollows crossing the punching cracks. These analyzed conclusions provide theoretical reference for the improvement of design method of this floor structure.
