    Review on Self-centering Energy Dissipative Steel Frame Joints Between Beam to Column

    • 摘要: 为了解决自复位耗能钢框架梁柱节点中附加耗能构件耗能稳定性不足,附加复位构件应用过程复杂、变形能力较低、安全储备度及性价比不高,自复位耗能钢框架整体结构性能化设计方法适用性不强等问题,从附加复位及耗能构件的种类选择、其与钢框架的连接应用构造及该类型节点所在整体结构的性能化设计几个方面对现有自复位耗能钢框架梁柱节点的研究进行了综述和分析,明确了现有研究中的不足,指出了今后自复位耗能钢框架梁柱节点需要进一步深入研究的关键问题。

       

      Abstract: In order to solve the problems of insufficient energy dissipative stability, complex application processes,low deformation ability,low safety reserve and low cost-effectiveness of additional self-centerting components in self-centerting energy dissipative steel frame joint between beam to column, poor applicability of performance-based design methods of self-centerting energy dissipative steel frame structure,a review and analysis on existing researches have been conducted in several aspects,including the selection of types of additional self-centerting and energy dissipative components,the construction of their connections with steel frames,and the performance-based design of the overall structure where these types of joints are located. The shortcomings of existing researches are clarified,and the key issues of self- centerting energy dissipative steel frame joint between beam to column, which need to be further investigated are addressed.
