ABSTRACT

Tall buildings featuring transfer structures are commonly constructed in lower seismicity regions. Discontinuities in load paths of structural systems in the building were found to compromise ductility of the building. In a force-based seismic design procedure, response modification (R) factor is uncertain to cater for the undesirable features. This article presents a methodical approach for evaluating the seismic performance of such buildings. Results of incremental dynamic analyses of case study buildings indicated a high R-factor, due to the inherent over-strength. A local amplification factor (βDT)is recommended to account for localised shear at structural walls above the transfer floor level.

增量动态分析具有重力传递系统的建筑物的地震响应修正因子

摘要

具有转移结构的高层建筑通常建在地震活动性较低的地区。发现建筑物中结构系统的载荷路径的不连续性会损害建筑物的延展性。在基于力的抗震设计过程中,响应修正 ( R ) 因子不确定以适应不良特征。本文提出了一种评估此类建筑物抗震性能的系统方法。案例研究建筑物的增量动态分析结果表明,由于固有的超强度,R因子较高。局部放大因子 (βD)建议考虑转移地板水平以上结构墙的局部剪力。
