ajst-22345	Yang, Qihao; Liu, Shuping	Strength Optimisation and Static Performance Analysis of Arch Ribs of Steel-tube Concrete Arch Bridge	2024	6	.pdf	application/pdf	5013	191	59	The research around steel pipe concrete arch bridges mainly focuses on the five aspects of hollow steel pipe concrete arch ribs[18], arch axis line shape[19], arch axis coefficients, arch rib girder heights, transverse coupling arrangement, column arrangement[20], hollow steel pipe concrete hollow ratio and wall thickness of steel pipe section[21], transverse bracing structural forms and their stiffnesses[22], the comprehensive cost of arch ribs[23], the sagittal-span ratio[24], and the arch rib isotropic cross-section optimization analysis[25], etc., there are fewer studies on arch bridges with different new steel-tube concrete structures. Due to the lack of in-depth research and relevant design specifications, these new types of steel pipe concrete structures are rarely used in steel pipe concrete arch bridges.	cache/ajst-22345.pdf	txt/ajst-22345.txt
