摘要: 廣東省標準《建筑工程混凝土結(jié)構(gòu)抗震性能設(shè)計規(guī)程》(DBJ/ T 15-151—2019)提出一套與我國抗震規(guī)范體系接軌的基于構(gòu)件的鋼筋混凝土結(jié)構(gòu)抗震性能設(shè)計方法:小震構(gòu)件承載力設(shè)計,大震構(gòu)件承載力和變形復核. 以AutoCAD 為基礎(chǔ)開發(fā)基于構(gòu)件的結(jié)構(gòu)抗震性能評估 BIM 平臺 PBSD,該平臺深度融入《建筑工程混凝土結(jié)構(gòu)抗震性能設(shè)計規(guī)程》(DBJ/ T 15-151—2019),對強震作用下構(gòu)件的承載力、變形及損傷程度進行評估,從構(gòu)件層次反映結(jié)構(gòu)整體抗震性能. 最后利用該平臺對某超高層結(jié)構(gòu)進行抗震性能評估,分析結(jié)構(gòu)在罕遇地震作用下的損傷程度,揭示結(jié)構(gòu)的屈服機制,充分論證該超高層結(jié)構(gòu)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
