Abstract: Concrete-encased concrete-filled steel tube (CFST) is an innovative composite member that consists of the inner CFST components and an outer reinforcement concrete encasement. One increasing application scenario of ...

Abstract: In concrete-filled steel tubular (CFST) truss structures, the welded joints that connect the CFST chords and hollow steel tube braces are particularly susceptible to fatigue cracking due to high stress concentrations. ...

Abstract: An innovative two-phase model updating technique is developed to accurately assess the mechanical state of an in-service cable-stayed bridge. In the first stage, a sensitivity analysis is performed to select the updating ...

Abstract: This paper reports the results of 120 low-cycle fatigue tests on steel reinforcing bars with varying slenderness ratios at varying strain amplitudes. The failure modes of the fractured bars were investigated through analysis ...
