intermediate bearing
1.Problems in using screw-crane in fields and water resources engineering were analysed with examples of engineering project.Based on this,a method was presented.By using double-hook screw-crane and connecting two screw-cranes by an intermediate bearing and a gear coupling,the problem of inefficiency in door-closing was solved.The double-hook screw-crane could work synchronously.
2.Based on the analysis and comparison of influences of various intermediate support bearing types on the internal forces of the curved girder bridges, the applicable conditions of the different hearing types for design of the curved girder bridges with fairly narrow decks and sharp radii have been obtained.
3.Abstract: Based on the test and analysis of 12 short restrained reinforced concrete columns with intermediate longitudinal bars,an analysis model is established to calculate the shear bearing capacities of the short columns subjected to axial load, bending moment and shear force,and with the intermediate longitudinal bars considered, the calculating formulae are derived.
