构造配筋对梁式结构温度收缩裂缝影响分析

Analysis on the influences of constructional reinforcement on temperature-shrink cracks of beam structure

对温度收缩裂缝的影响因素进行了研究,分析了构造配筋对混凝土梁温度收缩裂缝的影响,用"等效荷载法"计算了混凝土简支梁的温度收缩应力和应变,以解决混凝土梁式结构的温度收缩裂缝问题。

Based upon study of influencing factors of temperature-shrink cracks the influences of constructional reinforcement on temperatureshrink cracks of concrete beam are analyzed. Utilizing equivalent load method the temperature shrinkage stress and strain of concrete simple beam are calculated in order to resolve temperature-shrink cracks problem of concrete beam structures.
