摘要
本文对4根区域约束混凝土梁及1根普通钢筋混凝土梁进行了静力破坏试验,对其试验刚度进行了分析,同时在考虑约束混凝土作用的基础上对其理论刚度进行了计算。试验及理论计算结果均表明,区域约束的配箍形式能有效提高构件的刚度。
Experiments were done on 4 regional confined concrete beams and 1 normal confined concrete beams under static destruction test. And the stiffness of the test was analyzed. At the same time,the theoretical stiffness of beams was calculated considering the effect of confined concrete. Both test and theoretical calculation results show that the form of the regional constraint can effectively improve the stiffness of the component.
