浅谈钢筋混凝土框架梁中的拱效应

The Discussion on the arching action in the Reinforce-Concrete Frame Beam

钢筋混凝土受弯构件中存在拱效应,而且可以有效地提高受弯构件的承载能力。通过对钢筋混凝土框架梁试件的试验可以充分证明拱效应的存在和对其承载力的提高性能,并对其进行适当理论分析,试图找出影响拱效应的因素,为工程实践提供参考。

There is the arching action in the reinforce-concrete bending member,and it can improve the bending member＇s carrying capacity effectively. Through the test of the reinforce-concrete frame beam,we prove that the arching action is in it and can improve the carrying capacity of the reinforce-concrete frame beam. So, we do the theoretical analysis to find the factor of the arching action,and to provide the consultations for the project.
