Fatigue analysis of steel box girder in key sections for threetower suspension bridge under random vehicle

Chen Ce,Ji Bohai and Liu Rong

Strategic Study of CAE 2012, Volume 14, Issue 5,   Pages 75-79

Abstract:

Taizhou Bridge is the first kilometer level threetower and twospan suspension bridge in the world. The three-dimensional fullbridge FEM (finite element method) model of the Taizhou Bridge and the random vehicle loading on the bridge finite element model by simplified vehicle load model are established. The vertical displacement and bending moment values are calculated to analyze the position of the maximum stress for the steel box girder under vehicle load. Then the critical position can be determined to carry out fatigue analysis for the steel box girder.

Keywords： three-tower suspension bridge     orthotropic plate     fatigue stress analysis     key sections

Hot-dip galvanizing of cold-formed steel hollow sections: a state-of-the-art review

Min SUN, Jeffrey A. PACKER

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 1,   Pages 49-65 doi: 10.1007/s11709-017-0448-0

Abstract: A good understanding of the effects of galvanizing on the short- and long-term behaviours of steel components is essential for structural design. This review paper is motivated by a series of recent reports on cracking in galvanized cold-formed tubular steel structures and the limitations of current steel product standards and steel design specifications in this field. The steel-related and galvanizing-related factors, different pre-galvanizing countermeasures for brittle cracking and the available technical documents are summarized. An extensive bibliography is provided as a basis for future research and development in this field.

Keywords： cold-formed steel     hollow structural sections     hot-dip galvanizing     embrittlement     heat-treatment     residual

Engineering 2017, Volume 3, Issue 4,   Pages 559-566 doi: 10.1016/J.ENG.2017.04.021

Abstract:

To understand the resource features and geology in the deep Jinchuan nickel deposit, difficult geological conditions were systematically analyzed, including high stress, fragmentized ore rock, prevalent deformation, difficult tunnel support, complicated rock mechanics, and low mining recovery. An integrated technology package was built for safe, efficient, and continuous mining in a deep, massive, and complex nickel and cobalt mine. This was done by the invention of a large-area continuous mining method with honeycomb drives; the establishment of ground control theory and a technology package for high-stress and fragmented ore rock; and the development of a new type of backfilling cement material, along with a deep backfilling technology that comprises the pipeline transport of high-density slurry with coarse aggregates. In this way, good solutions to existing problems were found to permit the efficient exploitation and comprehensive utilization of the resources in the deep Jinchuan nickel mine. In addition, a technological demonstration in an underground mine was performed using the cemented undercut-and-fill mining method for stressful, fragmented, and rheological rock.
