Abstract
In this paper, girders with wall having seismic slits were modeled and a two-dimensional static elasto-plastic finite element analysis was performed. The parameters were girder section, span, main bar, concrete strength, slit wide and wall thickness. 111 models were analyzed. Key observations include the followings:(1) The stiffness K and α_y・K of girder with wall having seismic slit was large.(2) The effect of slit wide for the relationship between shear and relative displacement was small.(3) The effect of wall thickness for the elastic and plastic increasing ratio was small.(4) The effect of concrete strength for the elastic and plastic increasing ratio was small.(5) The elastic and plastic increasing ratio was derived by using the equations (9) and (10).
