摘要
采用有限元软件,分析了沈阳某超长地下商城的温度应力,并根据计算结果,提出了设置后浇膨胀加强带、采用补偿收缩混凝土和按计算加大梁板配筋等技术措施,可有效降低温度应力的影响,限制结构裂缝开展。
The paper adopts the finite element software,analyzes the temperature stress of some underground shopping mall in Shenyang City,and points out the allocation of post-pouring strengthening band and adoption of shrinkage-compensation concrete and calculation of widened beam plate reinforcement,so as to lower the temperature stress and limit the structural cracks.
