multi-girder
3.By making use of subdomain weighted residuals method, the internal forces of curved multi-girder bridge is analysed in this paper.
4.In the paper, the thin-walled beam theory has been directly combined with the analytic finite strip technique to derive the elastic governing differentil equations for curved multi-girder bridges by the principle of minimum potential energy.
5.Design of multi-used heavy half-hanging train with low-board straight girder type
6.A butterfly-shape arch bridge in Zhongshan City is a multi-element spatial structure composed of inclined steel arch ribs, curved steel box girder and inclined suspenders, and the structural behavior of the bridge is particularly complicated.
7.This paper has given below main fruits:(1). By monitoring loosening status of rock around the lanes after digging with the aid of multi points displacement apparatus, we can get the loosening range of the rock under deep coal to be about 4.0~5.0m on the support of archer-net-girder-jet;
8.New five-stage cyclone pre-heater system, high efficiency air girder grate cooler, multi-passage pulverized coal burner, Davison heat temperature fan, Luqi BS930 electrical dust collector, as well as chain-board elevator, chain conveyor adopted in this production line can ensure that the technology is advanced compared to other production lines with the same scale.
