钢侧撑韧性斜撑构材之行为与应用(Ⅰ)
|
摘要
韧性斜撑构材由主受力组件与侧撑组件组成,主受力组件承担轴力而侧撑组件则在防止主受力组件受压挫屈,由于主受力组件不挫屈,因此能充分发挥材料之强度与韧性,成为一高强度且具高消能容量之斜撑构材。以韧性斜撑构材作为同心斜撑构架中之斜撑构材,此同心斜撑构架即称之为韧性同心斜撑构架,此种构架具有稳定之迟滞行为与高韧性之特性,为一优良之耐震结构系统。本文叙述韧性斜撑构材与韧性同心斜撑构架之力学与耐震行为,并根据其力学与耐震行为提出建议之设计方法。本文为第一部分。
A buckling inhibited brace (or BIB) is composed of a main load-carrying element and a lateral support element. The main load-carrying element carries the axial forces transferred to the brace, and, the lateral support element prevent the load-carrying element from buckling while it is under compression. Since BIBs do not buckling under compression, they possess the characteristics of high strength and high energy dissipation capacity. BIBs can be used in a concentrically braced frame as bracing members, and, this type of frame is named as ductile concentrically braced frame (or DCBF). DCBF is an excellent earthquake-resistant structural system. In this research, the behavior of BIB and DCBF is investigated, and design methods for BIB and DCBF are proposed accordingly.This is the first part of the article.
