摘要

摘要: 柔性连接节点作为外挂墙板和框架结构的一种连接方式，设计目标旨在罕遇地震下发生限位后为框架提供额外刚度，而在非罕遇地震下仅起到连接作用。在不同频遇设防和罕遇地震下，为研究一定刚度外挂墙板对框架结构抗震性能的影响，建立了空框架和空间动态限位框架的纤维模型，对比分析了动力特性和动力响应。研究结果表明：当外挂墙板在设防地震作用下未滑动至限位点时，结构的加速度和变形响应相较于空框架有所增加，且层间位移角满足相应规范要求，外挂墙板仅起到提高框架整体质量的作用。当外挂墙板在罕遇地震作用下滑动至限位点时，结构加速度和变形响应相较于未限位的外挂墙板框架有所降低，其为框架结构提供额外刚度，提高了框架结构在罕遇地震下的抗震性能。

Abstract: Flexible connections serve as a link between cladding panels and the frame. They are designed to enhance the frame’s stiffness by limiting movement during rare earthquakes， while functioning solely as connections during non-rare earthquakes. To investigate the impact of cladding panels with specific stiffness on the seismic performance of frame structures subjected to varying levels of frequent fortifications and rare earthquakes， fiber models of both bare frames and spatial dynamic limiting frames were developed. A comparative analysis of their dynamic characteristics and responses was conducted. The results indicated that when the cladding panels with a certain stiffness did not slide to the limit point during seismic events， the acceleration and deformation responses of the structure increased relative to that of the bare frame. However， the inter-story drift ratio remained within specification limits， suggesting that the cladding panels primarily contributed to the overall mass of the frame. Conversely， when the cladding panels did slide to the limit point during rare earthquakes， the structural acceleration and deformation responses decreased compared to those of the frame with unrestricted cladding panels. This behavior provided additional stiffness to the frame structure， thereby improving its stability and seismic performance during rare earthquakes.
