Effect of fiber angle on LYP steel shear walls behavior

Abstract

Steel shear wall (SSW) was properly determined using numerical and experimental approaches. The properties of SSW and LYP (low yield point) steel shear wall (LSSW) were measured. It is revealed that LSSW exhibits higher properties compared to SSW in both elastic and inelastic zones. It is also concluded that the addition of CFRP (carbon fiber reinforced polymers) enhances the seismic parameters of LSSW (stiffness, energy absorption, shear capacity, over strength values). Also, stress values applied to boundary frames are lower due to post buckling forces. The effect of fiber angle was also studied and presented as a mathematical equation.
