Use of inclined studs in steel-plate-concrete composite walls with shear and axial loading

摘要

An analytical study is conducted to examine the effect of shape and spacing of inclined shear studs in steel-plate-concrete composite walls subject to shear and axial loading. Finite-element analyses of steel-plate-concrete shear walls were carried out considering different shapes and spacing of the studs. It was found that the shape of the studs has little effect on shear performance compared to spacing. When the studs are widely spaced, composite action is poor, the steel plate yields under a relatively minor load and the concrete is damaged. If spaced too closely, the studs also damage the concrete due to excessive restraint. It was also confirmed that inclined studs are more effective than normal studs for controlling buckling.
