摘要
利用ANSYS有限元软件,对实际的建筑结构进行合理的简化,模拟得出在降温荷载作用下结构温度应力的大小及其分布规律。并分析了此地下停车场现浇混凝土顶板温度裂缝产生的原因,提出了在设计和施工方面进行裂缝控制的建议。
Utilizing finite dement software-ANSYS reasonable simplification of structure is made. Based upon simulation analysis the value of temperature stress as well as its distribution regularity in falling process is obtained. In view of concrete cracks on roof slabs in this underground car park their causing reasom are analyzed; at the same time suggestions are proposed from two aspects： ocaastruction and design for cracks control.
