摘要

本文对具有传递单元的高层建筑的抗震性能进行了研究。采用反应谱(RS)和时程(TH)方法对3座既有转换板又有转换梁的钢筋混凝土(RC)建筑进行了分析。对每幢建筑进行了层剪力、弯矩、位移、位移和时间周期的计算。并采用推覆分析(POA)方法评价了这些建筑抵抗预期地震荷载的能力。研究结果表明，采用推覆分析得到的基础剪力值为采用静力法计算得到的基础剪力值的50% ~ 83%。此外，计算了这些建筑物的响应修正因子R，以显示其对建筑物不规则性的敏感性。对于本研究中研究的案例，建筑规范中给出的R值对于带有转换板的案例被高估了，而对于带有转换梁的案例被低估了。

Seismic Assessment of High-Rise Buildings Having Transfer Elements

This paper investigates the seismic behavior of high-rise buildings having transfer elements. Three constructed reinforced concrete (RC) buildings having either transfer slabs or transfer girders were analyzed using the response spectrum (RS) and time-history (TH) methods. For each building, the story shear, bending moment, displacement, drift, and time period were obtained. Furthermore, pushover analysis (POA) method was conducted to evaluate the capability of these buildings to resist the expected seismic loads. Results of the studied buildings showed that, the base shears obtained using pushover analysis are ranging between 50% to 83% of those calculated using the static approach. In addition, the response modification factors (R) for these buildings were calculated to show their sensitivity due to the irregularity of buildings. For the studied cases in this research, the R values given in the building codes were overestimated for the cases with transfer slabs and underestimated for cases with transfer girders.

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
