Abstract

Abstract

Based on the study on ultimate strength test of full-size falsework in 5 different operating conditions,and by the introduction of a stable bearing capacity test of the falsework,a three-dimensional finite element model is set up,with which the effect of generalized initial imperfections on the structural stability can be analyzed more accurately.It is further shown through on-site testing that the geometric imperfections of the partially-braced frame column may be replaced by the equivalent notional lateral load.Moreover,generalized equivalent notional lateral loads participate in all of the load combination.
