温度作用下超精电子厂房大跨度楼板力学性能
Mechanical Properties of Large-Span Slab of Ultra-Precision Electronic Factory Under Temperature Action
摘要
Abstract
Based on the ultra-precision electronic factory of Tianma Optoelectronics Limited Company of Xia-men City,Fujian Province,ABAQUS finite element software was used to simulate 3-dimensional(3D)model of the beam-slab structure,the simulation data and the monitoring data from the construction site were com-pared.The influence of temperature action on the ultra-long structure with large-span slab was studied from the slab thickness,reinforcement ratioes,and concrete strength grades,and parameter value suggestions were proposed for actual engineering.The study shows that the influence of temperature action on the slab stress is positively correlated.Under temperature action,the reinforcement ratioes of the slab have a significant impact on the stress and deformation of the floor slab,while the strength grades of concrete only have a significant im-pact on the deformation of the floor slab,and the the slab thickness has a certain impact on the stress of the floor slab.The temperature difference has a certain impact on the deformation of the central floor.关键词
