钢筋混凝土结构墙是多层建筑中的一种抗侧力体系，在风荷载作用下产生弹性变形，在地震作用下在底部形成塑性铰。过去的研究表明，塑性拉伸需求和随后的负载反向可能会导致塑性，局部的横向不稳定的墙壁。虽然侧向稳定性是由一些建筑规范，塑性屈曲很少直接解决。2010年和2011年，新西兰经历了地震，破坏了许多结构墙建筑，并观察到塑性屈曲。本文重新审视两个现有的局部屈曲模型，使用一系列的数据源。回顾以往的实验工作评估模型的准确性预测塑性屈曲能力。对一系列墙体进行了参数研究，考察了对塑性屈曲承载力影响最大的变量。此外，三个非线性时程分析的建筑物受到2010年和…
AbstractReinforced structural walls are often implemented as a lateral force resisting system in multistory buildings, designed to deform elastically under wind loads and form plastic hinges at their base under seismic excitation. Past research suggests plastic tensile demands and subsequent load reversals can cause a plastic, localized lateral instability in walls. Although lateral stability is addressed by some building codes, plastic buckling is rarely directly addressed. In 2010 and 2011, New Zealand experienced earthquakes that damaged many structural wall buildings, and plastic buckling was observed. This paper re-examines two existing local buckling models using a range of data sources. A review of prior experimental work assesses the models’ accuracy at predicting plastic buckling capacities. A parametric study on a range of walls examines the variables most influential to affect plastic buckling capacities. Additionally, three nonlinear time history analyses of buildings subjected to the 2010 and...
