摘要

介绍了一种新型的铜框架梁柱节点形式

其中预应力钢绞线提供了结构在地震作用下的复位功能（自定心）

设置在梁端下翼缘的摩擦件则为结构提供了耗能能力;介绍了下翼缘摩擦式自定心钢框架粱柱节点的构造和工作原理

以节点的低用反复加载试验结果为依据

利用面向对象的开放式计算程序OpenSees建立了节点的数值模型

并侧重于模拟节点在地震作用下的张开/闭合、自定心、摩擦耗能以及螺栓受剪等特性。由计算结果与试验结果对比可知

所建立的数值模型对节点的抗震性能具有良好的模拟效果。

Abstract

This paper presents a novel beam-column connection for steel moment resisting frames

in which the post-tensioning forces provide the ability of self-centering under earthquake

and the bottom flange friction device（BFFD）

located at beam ends

provides the energy dissipation.The operation principle and constitution of the BFFD connection are presented.Based on the low cyclic test results of the BFFD connection

a numerical model is established by using the Open System for Earthquake Engineering Simulation （OpenSees） to model the hysteretic behavior of the BFFD connection

including the gap opening/closing

self-centering

friction energy dissipation and the bolt bearing

etc.Comparison between the numerical simulation and the experiment results shows that the proposed numerical model can accurately simulate the hysteretic behavior of the BFFD connection.
