［摘要］對于層高較高、柱跨較大的超長結(jié)構(gòu)，創(chuàng)新性地提出采用設(shè)置屈曲約束支撐的框架結(jié)構(gòu)體系，并將該結(jié)構(gòu)體系應(yīng)用在實際工程——中國（淮安）國際食品博覽中心（B區(qū)）中。采用YJK，ETABS軟件對結(jié)構(gòu)在多遇地震、設(shè)防地震、罕遇地震作用下的抗震性能進(jìn)行分析，同時采用ABAQUS軟件對典型屈曲約束支撐連接節(jié)點進(jìn)行有限元分析。結(jié)果表明，對展覽建筑，在框架結(jié)構(gòu)中設(shè)置屈曲約束支撐能有效增強結(jié)構(gòu)的抗側(cè)、抗扭剛度，并能同時降低溫度作用對結(jié)構(gòu)的不利影響，另外，由于屈曲約束支撐的消能減震功能，使得結(jié)構(gòu)在中震、大震中具有更好的抗震性能。

Abstract:For the super long structure with high story height and large column span, the frame structural system with buckling restrained braces was innovatively proposed and applied to the actual project of China (Huai′an) International Food Expo Center (Area B). YJK and ETABS softwares were used to analyze the seismic performance of the structure under frequent earthquake, fortification earthquake and rare earthquake. At the same time, ABAQUS software was used to analyze the typical connection joints for buckling restrained braces. The results show that, for exhibition buildings, setting buckling restrained braces in the frame structure can effectively enhance the lateral and torsional stiffness of the structure, and can reduce the adverse effect of temperature on the structure at the same time. In addition, due to the energy dissipation function of buckling restrained braces, the structure has better seismic performance under fortification and rare earthquakes.
Keywords:China (Huai′an) International Food Expo Center; exhibition building; buckling restrained brace; frame structure; seismic performance
