不幸的是，现有的概率地震灾害研究报告对迪拜地震活动的估计存在显着差异。鉴于迪拜经济的快速增长，评估各种估算对建筑性能和成本的影响至关重要。这项研究调查并量化了迪拜高强度和中度地震活动估计对 6 层、9 层和 12 层建筑的抗震性能以及建造和维修成本的影响。参考建筑由钢筋混凝土组成，并配有特殊剪力墙作为其抗震力系统。使用非线性静态和增量动态分析来研究抗震性能。评估与地震损坏相关的建筑和维修成本，以量化影响。结果表明，针对更高地震活动度的设计可显着提高整体结构性能。此外，较高的地震活动估计导致初始建设成本略有增加。然而，抗震性能的显着增强和地震损失的减少抵消了初始投资的增加。当考虑到减少维修和停机成本时，这可以节省总体成本。 (C) 2017 年美国土木工程师学会。
Unfortunately, available probabilistic seismic hazard studies are reporting significantly varying estimates for seismicity of Dubai. Given Dubai's rapid economic growth, it is crucial to assess the impact of the diverse estimates on the performance and cost of buildings. This research investigates and quantifies the impact of the high and moderate seismicity estimates of Dubai on the seismic performance and construction and repair costs of buildings with 6, 9, and 12 stories. The reference buildings are made up of reinforced concrete with special shear walls as their seismic force-resisting system. The seismic performance is investigated using nonlinear static and incremental dynamic analyses. Construction and repair costs associated with earthquake damages are evaluated to quantify the impact. Results showed that designing for higher seismicity yields significant enhancement in overall structural performance. In addition, the higher seismicity estimate resulted in slight increase in initial construction cost. However, the increase in initial investment is outweighed by significant enhancements in seismic performance and reduction in earthquake damages. This resulted in overall cost savings when reduction in repair and downtime costs are considered. (C) 2017 American Society of Civil Engineers.
