摘要

峰值楼层漂移要求地震施加在建筑物上,可以通过详细的工程地震评估进行评估,或者在建筑物装有仪器的情况下进行记录。然而,对于大量建筑物的快速地震评估,需要一种简化的方法来估计楼层偏移需求。因此,本文提出了一种快速估算钢筋混凝土框架建筑楼层偏移需求的简化方法。通过利用基于位移的地震设计和评估方法中的概念和简化,开发了作为地面运动强度函数的峰值楼层漂移需求的表达式。该方法的性能是通过将预测的楼层漂移需求与一些案例研究建筑的严格非线性时程分析结果进行比较来衡量的。有希望的结果表明,所提出的方法将有助于快速评估现代RC框架建筑中一系列漂移敏感元件受损的可能性。

Rapid assessment of peak storey drift demands on reinforced concrete frame buildings
The peak storey drift demands that an earthquake imposes on a building can be assessed through a detailed engineering seismic assessment or recorded if a building is instrumented. However, for the rapid seismic assessment of a large number of buildings, it is desirable to have a simplified means of estimating storey drift demands. Consequently, this paper proposes a simplified means of quickly estimating storey drift demands on reinforced concrete (RC) frame buildings. Expressions for peak storey drift demand as a function of ground motion intensity are developed by utilising concepts and simplifications available from displacement-based seismic design and assessment methods. The performance of the approach is gauged by comparing predicted storey drift demands with those obtained from rigorous non-linear time-history analyses for a number of case study buildings. The promising results suggest that the approach proposed will be useful for rapidly assessing the likelihood of damage to a range of drift-sensitive elements in modern RC frame buildings.
