Numerical Simulation of Buckling of Steel Plates in Bolted SidePlated Reinforced Concrete Beams

Abstract:

A parametric analysis using ABAQUS was conducted to study the effects of different buckling restraint measurements on the local buckling of steel plates in boltedsideplated (BSP) beams. The results show that the buckling behavior is not sensitive to the initial imperfection of the bolted steel plates; thicker steel plates result in a greater buckling strength; less bolt spacing and larger longitudinal stiffeners improve the buckling strength and decrease the lateral buckling camber; the buckling restraint caused by transverse stiffeners is ignorable; and the enhancement of buckling strength beneficial from longitudinal stiffeners can be divided into the yield strength of the stiffeners and the buckling restraint effect. The proposed fitted formulae can evaluate the buckling strength accurately.
