Approximate Analysis Method for ModularTubular Falsework
Publication: Journal of Structural Engineering
Volume 127, Issue 3
Abstract
This paper presents a derivation of exact expressions of moment-curvature relations of a circular tubular section. On the basis of these expressions and the observed behavior of full-scale specimens, an approximate method of second-order inelastic analysis applicable to pinned supported columns and modular falsework frames is presented. The approximate method is used to obtain load-deflection curves, and in the solution procedure, a set of simultaneous nonlinear equations is solved using MATHCAD. The load-deflection curves compare well with experimental results, and their application is helpful for verifying the quality of the modular tubular falsework units used in construction.
