Abstract:
According to the characteristics of steel-concrete composite frames, the composite effect of floor slab, real constraint degree between composite beams and columns as well as features of semi-rigid connection of joints were considered by using the calculation methods for equivalent stiffness of composite beams under the slip effect. The stiffness modified coefficients of composite beams of sway and non-sway semi-rigid composite frame columns were established and the stability design methods of sway and non-sway composite frame columns were put forward. Example analytical results show that the design method effectively makes use of composite effect and ductility of nodes, and has rather good economic benefits.
