新型机械装配式框架结构边节点受力性能分析

摘要

通过相同截面尺寸、相同材料强度、相同配筋的现浇混凝土框架结构边节点和机械装配式框架结构边节点的试验研究,对其裂缝开展过程、受力过程和破坏形态等受力性能进行分析,得出相对于现浇节点,干式连接的机械装配式框架边节点的承载力略低,但延性较好,弹簧装置可以起到帮助节点变形的作用.%Through the same cross-section,the same material,the same reinforcement strength of cast-in-situ concrete frame structure joints and mechanical assembly frame side joint test research,analysis of the development process,the process of force and the failure modes on the mechanical properties of the cracks,It is concluded that the beating capacity of the edge of the mechanical-mounted frame is slightly lower than that of the cast-in-place node,but the ductility is better and the spring device can help the deformation of the node.
