| 摘 要： | 目前国内的混合结构建筑，由于温度变化以及材料伸缩等原因引起的墙体裂缝现象较为普遍。根据混合结构房屋构件之间的相互约束以及协同工作的关系，文章提出了温度收缩应力和变形的近似计算方法。计算结果表明，与现场实测的结果吻合较好，计算公式可供工程实践参考。

| Abstract: | Wall cracks occur commonly in buildings of mixed structures in our country,and the main reason is the material contraction due to temperature variation.In this paper,a formula is proposed to evaluate the contraction stress and strain due to temperature variation in buildings of mixed structure based on the relationship of consistent functioning and mutual constraint among structural components.The theoretical results are well agreed with that of in situ experiments.Consequently,the theoretical formula is useful in engineering practice. |
