A rapid estimate of the damage state of a building after an earthquake event is of crucial importance, having the potential to minimise casualties and mitigate costs associated with structural damage and economic downtime. Visually determining the damage state accurately is often difficult, and so instrumentation can be installed to estimate the extent and locations of damage. However, the current minimum requirements of industry standard instrumentation layouts have thus far proven to be inadequate in providing sufficient information about the health of a structure after an extreme event. This paper investigates a simple, computationally inexpensive method for determining the interstory drift of all floors of a high-rise building using minimal instrumentation. The methodology proposed is applied to the Atwood building, a 20-story structure located in a highly seismic region of Anchorage, Alaska, that has been fitted with an extensive seismic monitoring system. The simulated results are shown to provide comparable results of displacement profile of a structure over time with respect to the elastic performance of the building. Importantly, the displacement profile allows a direct calculation of interstory drift, which can indicate the location and damage state of the building.

在地震事件发生后快速估计建筑物的损坏状态至关重要，它有可能最大限度地减少人员伤亡并降低与结构损坏和经济停工相关的成本。准确地目视确定损坏状态通常很困难，因此可以安装仪器来估计损坏的程度和位置。然而，迄今为止，行业标准仪器布局的当前最低要求已证明不足以提供有关极端事件后结构健康状况的足够信息。本文研究了一种简单、计算成本低的方法，用于使用最少的仪器确定高层建筑所有楼层的层间漂移。所提出的方法应用于阿特伍德大楼，位于阿拉斯加州安克雷奇地震多发地区的 20 层结构，配备了广泛的地震监测系统。模拟结果显示提供了结构随时间推移的位移剖面与建筑物弹性性能的可比较结果。重要的是，位移剖面允许直接计算层间漂移，这可以指示建筑物的位置和损坏状态。
