On the Elasto-Plastic Response of A Beam-column subjected to Dynamic Loadings under Constant Axial Thrust.

摘要

This study is concerned with an analysis of the elasto-plastic response of a beam-column. Author treats on cases of a beam-column subjected to constant axial thrust and dynamically varied lateral loads. The moment-curvature relation used for the analysis is obtained by using the simulation program of stress-strain relation of mild steel formulated by the author and other. As result, it is shown that the final deformation of a beam-column due to axial and dynamic lateral loads is affected greatly by the faithfulness of representing numerically the stress-strain relation of the material in general.
