［摘要］蘇州新聞大廈裙房為大面積斜板結(jié)構(gòu)，分析比較此類裙房結(jié)構(gòu)的建模方法及采用不同結(jié)構(gòu)體系的抗震性能。計算結(jié)果表明，對于此類存在大面積斜板的結(jié)構(gòu)，應(yīng)考慮斜板對結(jié)構(gòu)分析的影響；結(jié)構(gòu)體系應(yīng)考慮多道抗震防線，框-|剪力墻結(jié)構(gòu)體系的抗震性能要優(yōu)于框架結(jié)構(gòu)；采用一道抗震防線時，應(yīng)提高與斜板相連框架柱在設(shè)防地震及罕遇地震下的性能目標(biāo)。

Abstract:The podium of Suzhou News Building is a large-scale diagonal plate structure. The different modeling methods and structural systems were analyzed and seismic performances were compared. The calculation results show that the influence of the diagonal plate should be considered in structural design and multiple seismic resistant systems should be used in large-scale diagonal plate structures. The seismic performance of the frame shear wall structure is better than that of the frame structure. Performance objective of frame columns connected with diagonal plate should be improved under moderate and rare earthquakes when the single seismic resistant system was used.
Keywords:Suzhou News Building； diagonal plate; multiple seismic resistant system; dynamic elastic-plastic analysis; performance-based seismic design
