摘 要:為了實現抗震性能好且材料節能的結構體系,針對多層辦公樓案例,按照我國相關規范設計成鋼筋混凝土框架結構和框架薄殼結構,通過彈塑性動力時程分析比較了兩種結構體系的抗震性能、材料用量和CO2排放量。結果表明:兩種結構體系都能滿足“三水準”抗震設防目標;框架結構的最大樓層位移和最大層間位移角比框架薄殼結構大,罕遇地震下框架結構的損傷比框架薄殼結構嚴重;框架薄殼結構的混凝土、鋼筋用量和CO2排放量相比框架結構分別減少了 1 167.7 t、35.1 t和220 t;框架薄殼結構的抗震性能和節能減排性能明顯優于框架結構。
Abstract: 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 CO2 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 CO2 emission of the frame shell structure are reduced by 1 167.7 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.
