摘要:Abstract(#br)An arch under a central in-plane point load may lose its stability in an out-of-plane buckling mode when the load attends a certain value. This paper presents a theoretical study for the out-of-plane buckling of elastic circular arches under a central radial point lo...

摘要:Abstract(#br)This paper presents an analytical investigation of the thermoelastic lateral-torsional buckling of circular arches under an arbitrary radial point load in a uniform thermal environment accounting for shear deformations, which has not been reported in the literature. ...

摘要:Abstract(#br)The cyclic behavior and design of a triple-truss-confined buckling-restrained brace (TTC-BRB) is investigated, especially when it is used in mega-frame high-rise buildings and long-span spatial structures as a long-span BRB. The TTC-BRB is formed by introducing an ad...

摘要:Abstract(#br)This paper investigates the elastic buckling behaviour and load resistance of a double cross-arm pre-tensioned cable stayed buckling-restrained brace (DPCS-BRB) where an extra cross-arm is assigned within a longitudinal cable truss along its length. Naturally, the sp...

摘要:Abstract(#br)A new type of BRBs, namely a triple-truss-confined BRB (TTC-BRB) is proposed, and its hysteretic response is investigated experimentally and numerically in this paper. The TTC-BRB is formed through introducing an additional structural system of rigid trusses to the o...

摘要:Abstract(#br)In the non-linear in-plane elastic buckling and postbuckling analyses of shallow parabolic arches, to overcome the difficulty in deriving an accurate expression for the non-linear normal strain, an approximation assumption that the derivative of the vertical coo...

摘要:Abstract(#br)This paper presents an experimental study on the out-of-plane inelastic buckling strength of fixed circular steel arches under symmetric and non-symmetric loading. A test loading arrangement that allows for lateral deflections to develop freely under vertical loading...

摘要:Abstract(#br)This paper presents the long-term structural behaviour analysis and stability assessment carried out on concrete-filled steel tubular (CFST) circular arches. Linear and non-linear analyses are herein conducted for pin-ended and fixed arches subjected to a central con...

摘要:Abstract(#br)This paper reports experimental and numerical investigations used to develop a simple and accurate design method for the in-plane strength of circular steel I-section arches having a sinusoidal corrugated web under a uniform vertical load over the entire span. In def...

摘要:Abstract(#br)A circular arch with a uniform open thin-walled cross-section that is subjected to a radial load distributed uniformly around the arch axis may suddenly displace laterally and twist out of its plane of loading by buckling in a lateral-torsional mode. The classical so...
