Full-assembly type modular steel structure connecting joint with additional energy consumption
According to the full-assembly type modularized steel structure connecting joint with the additional energy consumption, T-shaped piece full-bolt connection is adopted between the module beam columns to replace a traditional welding connection mode, and the problem that the structure fails too early due to the fact that the quality of welding seams at the connecting positions of the module beam columns is unstable can be avoided while sufficient connection rigidity is ensured; the assembling degree of the structure is improved; the modified rubber plates are arranged on flanges of the module beams, additional friction energy consumption is provided through relative sliding between the modified rubber plates and the T-shaped connecting pieces, the initial friction level of the structure can be changed by adjusting pretightening force of corresponding bolts, the fullness degree of a node hysteretic curve is adjusted, and therefore different energy consumption requirements of the structure are met. The detail structure of the T-shaped connecting piece is reasonably designed, plastic deformation can be controlled in the connecting area of the flange plate and the web plate of the T-shaped connecting piece, an expected damage development mode is achieved, the initial performance of the structure can be recovered by rapidly replacing the T-shaped connecting piece after an earthquake, the life cycle of the structure is prolonged to a certain degree, the repairing cost is reduced, and the sustainable development requirement is met.
本发明为一种具有附加耗能的全装配式模块化钢结构连接节点，其模块梁柱之间采用T型件全螺栓连接代替传统焊接连接方式，在确保足够连接刚度的同时可避免因模块梁柱连接处焊缝质量不稳定而引发结构过早失效的问题，并提高结构装配化程度；模块梁翼缘设置改性橡胶板，通过与T型连接件之间的相对滑动提供附加摩擦耗能，可通过调整相应螺栓预紧力改变结构初始摩擦水平，调整节点滞回曲线的饱满程度，从而满足结构不同耗能需求；合理设计T型连接件细部构造，可将塑性变形控制在T型连接件的翼缘板与腹板连接区域，实现预期损伤发展模式，震后对其进行快速更换即可恢复结构初始性能，一定程度延长结构生命周期，降低修复成本，满足可持续发展要求。
