The in-plane elastoplastic failure mechanism of plate-tube-connected steel circular arches with inverted triangular cross sections is investigated in this study by using theoretical derivation and numerical simulation. First, the elastic buckling load formula arch under full-span uniform radial (FSURL) presented. Then, limited conditions avoiding connecting plate chord local before global insta...

A new method of robustness evaluation is proposed for an elastoplastic base-isolated high-rise building considering simultaneous uncertainties of structural parameters. Since it is difficult to evaluate the robustness of elastoplastic structures due to heavy computational load on the time-history response analysis including elastoplastic response, a double impulse input is used to provide a clo...

The curved plate has been extensively used as a structural member in many industrial fields, especially the shipbuilding industry. present study investigated ultimate strength and collapse behavior of simply supported under longitudinal compressive load. To do this, experimental apparatuses for evaluating buckling test plates was developed. Then, series experiments carried out by considering fl...
