混凝土核心筒结构体系在美国西海岸的高层住宅建筑中很普遍。为了评估该系统的抗震性能特征，在加利福尼亚州洛杉矶的一个场地设计了一座42层的核心墙住宅建筑。该建筑采用了两种不同的设计方法。第一个设计遵循美国建筑规范的规定要求，除了高度限制被忽略。第二种设计遵循基于性能的程序。每种设计的分析模型都受到一系列地震地面运动的影响，这些地震地面运动代表了非常频繁到非常罕见的震动强度。考虑到结构性能指标，初始成本和维修成本与预期的地震地面震动的各种设计方法的有效性进行评估。结果表明，这种结构体系的抗震性能潜力，并展示了一个实用的抗震性能评估方法的建筑物的应用。版权所有© 2012约翰威利父子有限公司.
Concrete core‐wall structural systems are prevalent for high‐rise residential buildings in the West Coast of the United States. To assess the seismic performance characteristics of this system, a 42‐story core‐wall residential building was designed for a site in Los Angeles, CA. The building was designed using two different design approaches. The first design followed prescriptive requirements of US building codes, except height limits were disregarded. The second design followed a performance‐based procedure. Analytical models of each design were subjected to a series of earthquake ground motions representative of very frequent to very rare shaking intensities. Effectiveness of the various design methods is assessed considering structural performance indices, initial costs, and repair costs associated with anticipated earthquake ground shaking. The results illustrate the seismic performance potential of this structural system and demonstrate the application of a practical seismic performance assessment approach for buildings.
