Experimental Study for Estimating Ultimate Strength of U-shaped Steel Girders in Shear

摘要

The critical factor in the construction of U-shapcd steel girder bridges, generally called open-box girder bridges, is the load capacity of the structural system under installation before the hardening of the concrete floor slabs. Therefore, it is important to measure the load capacity performance of the U-shaped sections. However, there have been no experimental studies on the load capacity performance of U-shaped sections. This experimental study revealed the shear load capacity characteristics of U-shaped sections.
