Sensitivity Analysis of Tubular-Web Reduced Beam Section Connections Under Cyclic Loading

Recently a new type of Reduced Beam Section (RBS) connection called “Tubular Web RBS (TW-RBS)” has been numerically and experimentally studied. TW-RBS connections are made by replacing a part of web with a tube or pipe at the desirable location of the beam plastic hinge. This paper aims to numerically investigate the effect of key factors such as position, diameter, and thickness of the tube on the hysteretic behavior of the connection under...
