梁侧钢筋对混凝土收缩的影响及其构造要求

Influence of Steels in Both Sides of Beam on the Concrete Shrinkage and Construction Requirements of the Steels

分析了混凝土梁侧出现温度收缩裂缝的原因,进而分析了梁侧构造钢筋对混凝土开裂的有利作用,验证了混凝土规范对梁侧构造钢筋的有关规定,最后采用ANSYS软件分析了降温时钢筋混凝土梁的应变云图,以此进一步验证了上述结论.

The reason why the temperature-shrinkage crack occurs in the reinforced concrete beam is researched,then the beneficial influence of the construction steel in the both sides of the beam on resistance crack is analyzed. The relevant requirements in the concrete code to the construction steels are verified. Finally, according to the ANSYS software, the strain clouds of the reinforced concrete beam are discussed when dropping the temperature, from which the research conclusions are fui＇ther tested.
