摘要:
为分析不设置伸缩缝的开洞华夫板受温度影响下楼板的应力及裂缝响应,采用ABAQUS有限元分析软件对开洞华夫板进行仿真模拟,对比工程实际,得到该类楼板在不同尺寸及温度变化下的应力、变形情况。结果表明:在日常温度变化下,核心区楼板均不超过计算应力限值,位移最大与应力集中主要出现在板柱节点处;随着混凝土强度上升,同温差下整体应力无明显变化,增量不大于2%,但楼板厚度的增加会导致应力突变及变形趋势的改变;考虑对跨度较大的钢筋混凝土楼板进行分块施工,合理控制板块间的温差为15~30 ℃,有利于整体浇筑后楼板的应力均匀分布。
Abstract:
In order to analyze the stress and crack response of the floor under temperature influence in perforated waffle plate without expansion joints, the ABAQUS finite element analysis software is used to simulate the perforated waffle plate, comparing with the engineering practice, the stress and deformation of this kind of floor under different sizes and temperature variations are obtained. The results show that under the daily temperature variation, the floor in the core area does not exceed the calculation stress limit, and the maximum displacement and stress concentration mainly appear at the slab-column joints. With the increase of concrete strength, the overall stress has no obvious change under the same temperature difference, and the increment is less than 2%, but the increase of floor thickness leads to the sudden change of stress and the change of deformation trend. Considering the block construction of the reinforced concrete floor with large span, the reasonable control of the temperature difference between plates within 15-30 ℃ is beneficial to the uniform stress distribution in the floor after monolithic pouring.
