型钢混凝土框架—筒体混合结构截面尺寸初选

Preparatory selection of sectional dimension of steel reinforced concrete frame-tube composite structure

根据型钢混凝土框架—钢筋混凝土筒体混合结构的受力及变形特点,结合规范要求,提出了型钢混凝土框架—钢筋混凝土筒体混合结构初步设计阶段以结构刚度特征值为基础的设计方法,并用实例证明了该方法的可行性。

According to the mechanic and deformation characteristics of steel reinforced concrete frame-tube composite structure the design method taking eigenvalue of structural stiffness as basis in primary design stage of this composite structure is proposed. Combined with practice the feasibility of this method is verified.
