Analysis of Two Typical Reinforced Concrete Warehouse Top Trestle Bridges
In this paper,two typical reinforced concrete warehouse roof trestles in the grain industry werw analyzed from the aspects of structural force,construction cost and convenience of use,so as to provide reference for engi-neering designers and owners to make decisions.Combined with the grain storage and logistics project of the direct-ly affiliated library of the central reserve of grain in Guangan,and using midas gen modeling,the deformation and internal force of the two warehouse roof trestles under the dead load condition,live load condition and seismic load are obtained.By comparing the internal force and deformation results of the two trestles,the calculation results of the low trestle under the dead load condition,live load condition and seismic load are obviously better than the high trestle.From the perspective of the trestle components themselves,the low trestle is better than the high trestle in terms of material consumption and project cost.However,considering the equipment layout,personnel passage need to arrange steel ladder,steel platform,steel structure leg and other factors,the two schemes are basically flat in terms of material consumption and project cost.The high trestle scheme has large space under the bridge,which is convenient for the layout of process equipment and personnel passage.The high trestle is better than the low tres-tle in terms of convenience of use.
