摘要
为了实现抗震性能好且材料节能的结构体系,针对多层办公楼案例,按照我国相关规范设计成钢筋混凝土框架结构和框架薄壳结构,通过弹塑性动力时程分析比较了两种结构体系的抗震性能、材料用量和CO_(2)排放量。结果表明:两种结构体系都能满足“三水准”抗震设防目标;框架结构的最大楼层位移和最大层间位移角比框架薄壳结构大,罕遇地震下框架结构的损伤比框架薄壳结构严重;框架薄壳结构的混凝土、钢筋用量和CO_(2)排放量相比框架结构分别减少了1167.7 t、35.1 t和220 t;框架薄壳结构的抗震性能和节能减排性能明显优于框架结构。
In order to achieve a structural system with good seismic performance and materials saving,for the case of a multi-storey office building,a reinforced concrete frame structure and a frame shell structure were designed in accordance with Chinese relevant codes.The seismic performance,material consumption and CO_(2)emission of the two structural systems were compared through elasticplastic dynamic time history analysis.The results show that the two structural systems can meet the"three-level"seismic fortification goal.The maximum floor displacement and maximum interstory displacement angle of the frame structure are larger than those of the frame shell structure,and the damage of frame structure under rare earthquake is more serious than that of frame shell structure.Compared with the frame structure,the amount of concrete,steel bars and CO_(2)emission of the frame shell structure are reduced by 1167.7 t,35.1 t and 220 t respectively.The seismic performance,energy saving and emission reduction performance of frame shell structure are obviously better than those of frame structure.
