ABSTRACT

This work presents the results of a numerical investigation on the effect of light timber retrofit systems on the global response of URM cavity-wall buildings. The building object of the study is a two-storey cavity-wall terraced house, retrofitted with OSB panels and timber frames. The Applied Element Method, was chosen for the numerical analyses. Numerical models, calibrated on experimental data of both retrofitted and non-retrofitted walls, were validated through the simulation of a shake-table test of a full-scale retrofitted specimen. A parametric study was then conducted to investigate the influence of different retrofit layouts on the building’s global seismic response.

摘要

这项工作介绍了轻型木材改造系统对 URM 空腔墙建筑的全球响应影响的数值调查结果。该研究的建筑对象是一栋两层空心墙排屋，采用定向刨花板和木框架进行改造。选择应用元素法进行数值分析。数值模型根据改装和非改装墙壁的实验数据进行了校准，并通过模拟全尺寸改装样本的振动台试验进行了验证。然后进行了一项参数研究，以调查不同改造布局对建筑物整体地震响应的影响。
