砖混结构中的墙体温度裂缝的计算

Compute of Temperature Crack on Brick-Concrete Structure Wall

砖混结构中钢筋混凝土屋盖和墙体的线膨胀系数和刚度不同,当温度改变时,二者就会产生相对位移和内力,从而引起裂缝。裂缝的产生与二者之间的水平阻力系数、温度以及墙体截面尺寸和弹性模量有关。文章提出了六种防止裂缝产生的措施。

The linear expansion coefficient and stiffness of roof made by reinforced concrete are different from wall.The displacement and the internalforce between the roof and the wall are produced when temperature changes.Consequently the crack on the wall is begot.The crack is concerned with horizontal resistance coefficient,temperature,size of wall section,elastic modulus.In this paper,six measures of preventive crack were brought forward.
