Non-linear shape-finding analysis of a self-anchored suspension bridge
A non-linear shape-finding analysis is proposed for a self-anchored suspension bridge, the Yongjong Grand Bridge, the main cable of which is three-dimensional in shape. The proposed procedureExpand

Effect of post equal-channel-angular-pressing aging on the modified 7075 Al alloy containing Sc
Abstract The effect of post-ECAP low-temperature aging on mechanical properties of the 7075 Al aluminum alloy containing Sc (7 × 51) after a single pressing was examined. The best aging effect onExpand

Determination of hanger installation procedure for a self-anchored suspension bridge
For self-anchored suspension bridges, stiffening girders or trusses should be erected prior to the air-spinning of the main cables. Since hangers are installed between pre-constructed stiffeningExpand

Efficient combination of a TCUD method and an initial force method for determining initial shapes of cable-supported bridges
The TCUD method (Kim and Lee, 2001) can provides the reasonable initial shape of cable-supported bridges under full dead load by including the unstrained lengths of the cable members as unknowns andExpand

High-temperature rupture of microstructurally unstable 304 stainless steel under uniaxial and triaxial stress states
Specimens of 304 stainless steel were tested to failure under two different stress states, uniaxial tension using smooth bar specimens and triaxial tension using notched bar specimens. The tests wereExpand
