In order to improve the seismic performance of the structure with the frame normally in reinforced concrete beams and columns, the frame with steel reinforcing concrete is proposed.A simply calculation method for internal force of frame-supported shear wall and two formulas for the normal section design for steel reinforced concrete column are introduced. The method to determinate the load-bearing capacity of shear wall supported on the frame with steel reinforcing is given. As verification, a one-forth-scale model test under vertical and monotonic horizontal load was conducted.Keywords:steel reinforced concrete; shear wall supported on frame; transfer story; transfer beam; loadbearing capacity*国家杰出青年科学基金资助项目(50225825)。
