摘要: 广东省标准《建筑工程混凝土结构抗震性能设计规程》(DBJ/ T 15-151—2019)提出一套与我国抗震规范体系接轨的基于构件的钢筋混凝土结构抗震性能设计方法:小震构件承载力设计,大震构件承载力和变形复核. 以AutoCAD 为基础开发基于构件的结构抗震性能评估 BIM 平台 PBSD,该平台深度融入《建筑工程混凝土结构抗震性能设计规程》(DBJ/ T 15-151—2019),对强震作用下构件的承载力、变形及损伤程度进行评估,从构件层次反映结构整体抗震性能. 最后利用该平台对某超高层结构进行抗震性能评估,分析结构在罕遇地震作用下的损伤程度,揭示结构的屈服机制,充分论证该超高层结构的安全性.

Abstract: A component-based performance-based seismic design method of reinforced concrete structures in line withChinese seismic code system is proposed in Guangdong provincial standard Specification for performance-based seismic designof reinforced concrete building structure ( DBJ/ T 15-151—2019): component bearing capacity design under frequentlyearthquake, bearing capacity and deformation check under rare earthquake. A component-based seismic performanceevaluation BIM platform PBSD was developed based on AutoCAD, which is deeply integrated into Specification forperformance-based seismic design of reinforced concrete building structure (DBJ/ T 15-151—2019) to evaluate the bearingcapacity, deformation and damage of components under strong earthquakes and reflect the overall seismic performance of thestructure from the component level. Finally, by using this platform to evaluate the seismic performance of a high-risestructure, the damage of the structure under rare earthquakes was analyzed and the yield mechanism of the structure wasrevealed, which fully demonstrates the safety of the high-rise structure.

Keywords: seismic performance evaluation; reinforced concrete structure; BIM platform; component deformation;yield mechanism
