Abstract

High‐rise buildings with vertical setbacks are more prone to damage in the event of strong earthquakes. This paper presents an extensive parametric study on the seismic performance of reinforced concrete (RC) frame‐shear wall structures with different setback configurations. Five groups of RC frame‐shear structures with 30 setback configurations were designed. Before conducting extensive non‐linear time history structural analysis, modeling of main lateral force resisting systems including RC column and shear wall was validated using previous test results. By parametric analysis on both horizontal setback ratio and vertical setback ratio, the influences of setback on structural seismic performance in terms of dynamic property, inter‐story drift ratio, acceleration, energy dissipation, and damage condition were comparatively investigated. The overall conclusion is that setbacks caused more than 50% reduction of floor area or positioned at the middle and lower height should be avoided.

不同收进结构钢筋混凝土框架-剪力墙结构抗震性能的参数分析

在发生强烈地震时，具有垂直后退的高层建筑更容易受损。本文对不同收进配置的钢筋混凝土框架-剪力墙结构的抗震性能进行了广泛的参数研究。设计了五组钢筋混凝土框架-剪力结构，共有30种缩进结构。在进行广泛的非线性时程结构分析之前，使用先前的测试结果对包括RC柱和剪力墙在内的主要抗侧力系统的建模进行了验证。通过对水平回缩比和垂直回缩比的参数分析，比较研究了回缩对结构动力特性、层间位移比、加速度、耗能和破坏条件等抗震性能的影响。总体结论是，应避免因挫折而导致建筑面积减少50%以上或位于中下部高度。

期刊介绍： The Structural Design of Tall and Special Buildings provides structural engineers and contractors with a detailed written presentation of innovative structural engineering and construction practices for tall and special buildings. It also presents applied research on new materials or analysis methods that can directly benefit structural engineers involved in the design of tall and special buildings. The editor''s policy is to maintain a reasonable balance between papers from design engineers and from research workers so that the Journal will be useful to both groups. The problems in this field and their solutions are international in character and require a knowledge of several traditional disciplines and the Journal will reflect this. The main subject of the Journal is the structural design and construction of tall and special buildings. The basic definition of a tall building, in the context of the Journal audience, is a structure that is equal to or greater than 50 meters (165 feet) in height, or 14 stories or greater. A special building is one with unique architectural or structural characteristics. However, manuscripts dealing with chimneys, water towers, silos, cooling towers, and pools will generally not be considered for review. The journal will present papers on new innovative structural systems, materials and methods of analysis.
