［摘要］钢筋混凝土网格盒式筒中筒结构作为一种新型结构体系已经得到应用，为研究其在地震作用下的力学性能，本文将以唐山建华检测有限公司办公楼为例，进行罕遇地震作用下网格盒式筒-核心筒结构的弹塑性分析，利用EPDA软件进行弹塑性时程分析，研究该结构体系在罕遇地震作用下的层间位移角、结构位移等基本指标，重点关注框架和剪力墙连梁塑性铰出现的时间和分布以及剪力墙裂缝的分布情况。并根据分析结论，对该体系建筑的抗震设计提出了优化建议。

Abstract： Grid reinforced concrete frame structure, as a new structure system, has been applied into practice. In order to investigate its mechanical characteristics under seimic environment, the elastic-plastic of grid reinforced concrete frame structure under the impact of rare occurrence earthquake basing on a case study of Tangshan Jianhua Detection Limited Company office building was analyzed. Elastic-plastic analysis was carried out with the aid of EPDA software. Basic indexes as interlayer displacement angle and structural displacement were studied. The time and distributions of plastic hinge occurrences of frame structure and shear wall beam, as well as distribution of shear wall cracks have been paid significant focus. According to analysis results, advises on optimizing anti-seismic design of grid reinforced concrete were proposed.

Keywords: reinforced concrete; space-grid box-tube structure; time-history analysis
