摘要
The steel beam-concrete column(RCS)frame structure is composed of the reinforced concrete columns and the steel beams,which is a composite structure with the superior performances.This kind of the frame structure has been rapidly developed and widely used in the field of the civil engineering because of its high building applicability,the fast construction speed,the low cost of the foundation and the good mechanical properties.Various kinds of the large-span,heavy-load and high-rise buildings emerge in endlessly,and the requirement for the structural performance is becoming higher and higher.The reinforced concrete column-steel beam composite frame structure is a high-performance structural system with the broad development prospects in China because of its good mechanical performance,durability,fire resistance and the building use space.
