According to the structure design of a high-rise steel reinforced concrete building, the elastic and plastic analysis, calculation of steel reinforced concrete basic member and joints design are emphasis introduced. Compared with the reinforced concrete structure, the section of column is decreased, and the ductility is increased. So it is an economic and reasonable structure style.
Keywords: steel reinforced concrete; ductility; elastic and plastic analysis; layer model; plastic hinge
