Diagonal shear test
WebThe Italian code considers three in-plane modes of failure for URM walls. These are: one in flexure i. flexural toe crushing; and two in shear i. sliding and diagonal shear cracking. The analytical formula- tions related to each mode of failure are provided below: In-plane flexural toe-crushing: Vtc = αPDL. 2 heff (1 . fa 0. 85 fm) (8) WebExperimental results of cyclic reversed lateral force test on a two-story reinforced concrete shear wall sub-assemblage are simulated analytically by using the PERFORM-3D program. ...
