ABSTRACT

The poor out-of-plane behaviour of masonry infill-walls (MIW) in recent earthquakes, resulted in several casualties and economic losses. The main objective of this work is to present an experimental campaign comprised of four out-of-plane tests of full-scale MIW with the main goal to assess the possible effect of the previous damage, workmanship and test setup in the MIW out-of-plane behaviour. From the results, it was observed that the existence of the prior damage reduced the out-of-plane strength and energy dissipation of about 30% and 70%, respectively. The workmanship can introduce variations in the MIW response from 10% to 30%.

先前损坏、工艺和测试设置对砌体填充墙平面外行为可能影响的实验研究

摘要

在最近的地震中，砌体填充墙 (MIW) 的不良平面外行为导致了数人伤亡和经济损失。这项工作的主要目的是提出一个实验活动，其中包括四次全尺寸 MIW 的平面外测试，主要目标是评估 MIW 外的先前损坏、工艺和测试设置的可能影响-平面行为。从结果中可以看出，先验损伤的存在使面外强度和能量耗散分别降低了约 30% 和 70%。工艺可以在 MIW 响应中引入 10% 到 30% 的变化。
