Abstract:Static and fatigue tests have been conducted on Bi-Steel steel-concrete-steel sandwich beams. A truss mo with tapering web compression members is proposed for calculating the forces within the beams. The model gi conservative predictions of the failure loads and modes of the beams. A deflection equation has been developed taking account the slip between steel plates and concrete, giving good agreement with measured values. A fatigue life calcula method has been proposed which takes into account interaction of … Show more
“…Finite element analysis [7] confirms the above equation when s x / h c ≤ 1 and shows that it is conservative when s x / h c > 1. When s x / h c = 2, F B /F B1 = 1.5 (Fig.…”
