Experimental Study on Steel Beams Curved in Plan
Publication: Journal of Structural Engineering
Volume 121, Issue 2
Abstract
This paper is concerned with the ultimate load behavior of I-beams curved in plan. Results obtained from experiments on two sets of I-beams (one comprising rolled sections and the other built-up sections) are presented. The test results for deformations and ultimate strength are found to be in good agreement with the corresponding values predicted by using the elastoplastic finite-element analysis. The effects of residual stresses and radius of curvature to span-length ratio ( R /L) on ultimate strength are considered. Each beam was subjected to a concentrated load applied at an intermediate point where the beam was laterally restrained. Test results indicate that the load-carrying capacity decreases with the decrease in the R /L ratio.
