The In-Plane Ultimate Load of I-section Beam-Columns with Slender Web

The In-Plane Ultimate Load of I-section Beam-Columns with Slender Web Similar to plate girders with slender web, a welded I-section beam-column does not fail when its web buckles. To take advantage of this post-local-buckling strength, this paper at first presents a method for calculating the M-P-φ relationship of I-sections with buckled web and residual stresses. The in-plane ultimate load of beam-columns with slender web can then be calculated by using this M-P-φ relationship. Nine eccentrically loaded specimens were tested to failure. The agreement between the calculated and test results confirms the validity of the analytical method. Furthermore, a simplified design formula is presented for predicting the in-plane capacity of beam-columns with slender web. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Structural Engineering SAGE

Abstract

Similar to plate girders with slender web, a welded I-section beam-column does not fail when its web buckles. To take advantage of this post-local-buckling strength, this paper at first presents a method for calculating the M-P-φ relationship of I-sections with buckled web and residual stresses. The in-plane ultimate load of beam-columns with slender web can then be calculated by using this M-P-φ relationship. Nine eccentrically loaded specimens were tested to failure. The agreement between the calculated and test results confirms the validity of the analytical method. Furthermore, a simplified design formula is presented for predicting the in-plane capacity of beam-columns with slender web.
