对型钢混凝土梁柱框架结构、型钢混凝土柱-钢筋混凝土梁框架结构、纯钢筋混凝土框架结构进行分析,讨论三者在在不同的地震作用下的层间位移角、有害层间位移角、变形特征曲线上的区别。研究表明:型钢混凝土框架结构呈现剪切型的变形特征,薄弱层出现在首层及二层,大震最大层间位移角可取小震时对应数值的6.5倍进行估算,型钢混凝土框架结构更适用于8度半以上抗震设防烈度地区。
對型鋼混凝土樑柱框架結構、型鋼混凝土柱-鋼觔混凝土樑框架結構、純鋼觔混凝土框架結構進行分析,討論三者在在不同的地震作用下的層間位移角、有害層間位移角、變形特徵麯線上的區彆。研究錶明:型鋼混凝土框架結構呈現剪切型的變形特徵,薄弱層齣現在首層及二層,大震最大層間位移角可取小震時對應數值的6.5倍進行估算,型鋼混凝土框架結構更適用于8度半以上抗震設防烈度地區。

Comparative analysis of SRC structure and Reinforced concrete frame structure and a decision. of the difference of the interlayer displacement Angle, harmful drift angle, and deformation characteristic curve are presented in this paper. It is proved that SRC frame structure shows shear deformation characteristics and weak story appears in the first floor and second floor. The value of maximum interlayer displacement angle under severe earthquake can take 6.5 times that under small earthquakes. SRC frame structure is more suitable for seismic intensity more than half of 8 degrees.
