Shear resistance behaviour of steel plate shear wall and steel-concrete composite shear wall with two-side connection

Abstract:

In this paper the numerical simulation on steel plate shear wall(SPSW) and steel-concrete composite shear wall(SCSW) with two-side connection was carried out by the finite element software ANSYS.Performances of the two shear walls were investigated.Different mechanical behaviors between SPSW and SCSW with two-side connection were discussed in details.It is found that the depth-thickness ratio λ is a key parameter that influences the shear resistance behavior of SPSW with two-side connection.The concrete plate which completely restricts the out-of-plate displacement may be thin if the depth-thickness ratio of a wall is large enough.Due to the concrete plate supporting,stress distributions in the SCSW are changed obviously:the horizontal load transferring manners are changed from tension strip to cross-sectional shear in the steel plates.
