摘要: 结合某长103 m的高层病房楼工程,对其在环境温降和混凝土收缩下产生的温度、收缩应力进行有限元分析,提出解决温度、收缩应力的措施。通过利用合适的后浇带,提高预应力筋张拉效率,并结合施工过程及其后期的混凝土应力检测,验证温度和收缩应力分布的规律以及上述各种方法的有效性。Abstract: By the no-joint design of a 103 m long sickroom building,it is analyzed the tensile stress caused by concrete shrinkage and temperature decreasing,also put forward a series of techniques to control the cracks.Post-poured strip was used to enhance the prestressing effect of steel bars.It is verified the distribution regularity of temperature stress and shrinkage stress and effectiveness of the above techniques by stress detecting during and after construction.
