Based on the lateral stiffness of asismic wall with hole or not, simplified formulas to calculate the lateral stiffness of aseismic wall and column are derived. The concept of efficient area to resist shear force and it's calculating formulas are brought out.A method to determine the amount of asismic wall, which is useful to simplify the design of shear wall of brick masonry building with frame-shear wall structure at first two stories, has been put forward.
