摘要:
通过对2个新型装配式混凝土框架节点和1个现浇混凝土框架节点进行拟静力试验研究,对比分析装配式混凝土框架节点破坏特征、滞回曲线、骨架曲线、刚度退化和耗能能力等指标。研究结果表明:新型装配式混凝土框架节点比普通现浇混凝土框架节点具有较好的滞回性能,较高的耗能能力以及较缓的刚度退化。在满足梁筋锚固长度要求的前提下,预制梁内钢端头长度增加使框架节点抗震性能稍有提高。装配部分后浇混凝土可以提高框架节点的承载能力和刚度。采用ABAQUS有限元软件对节点进行数值模拟,发现模拟结果与试验结果吻合较好。
Abstract:
The reversed cyclic loading test was carried out for two new prefabricated concrete frame joints and onecast-in-situ concrete frame joint. The failure features, hysteresis curves, skeleton curves, rigidity degeneration and energy dissipation capacities of the prefabricated concrete frame joint are analyzed. The results show that the new prefabricated concrete frame joints have better hysteretic performance, higher energy dissipation capacity and slower stiffness degradation than ordinary cast-in-situ concrete frame joints. Under the precondition of satisfying the anchoring length of beam bars, the seismic performance of frame joints is slightly improved with the increase of the steel end connector length.Pouring the concrete in assembly partcan enhance the strength and stiffness ofthe joints.Using the ABAQUS finite element software, the simulation of the fabricated frame joint is carried out.The simulated resultsarein good agreement with the experimental results.
