To study the design method of sectional area and initial tension of wire rope brace of the prestressed braced steel moment frame structure system, theoretical analysis of this structure system is conducted in this paper. The lateral stiffness formula is derived. It reveals the lateral stiffness is related to the lateral stiffness of bare steel moment frame, story height, the distance between column and lower end of brace, story drift, material properties and sectional properties of wire rope. The lateral stiffness increases with the growth of story drift and the relationship curve is a concave shape. It is presented the initial prestress degree design formula and method in light of the criterion for determining initial prestress degree. The story drift decreases with the growth of wire rope sectional area and the relationship curve is a concave shape, in terms of this, a wire rope sectional area design formula and method are proposed. The validation of the proposed design formula and method of wipe rope brace is proved by an example analyzed using finite element software package ABAQUS.
