Simulation analysis of structural bearing capacity of gas-ribbed inflatable tent
To analyze the influence of different inflation internal pressures on the bearing capacity of gas-ribbed inflatable tents,a finite element model of a large-span arched tent structure is built,including gas-ribbed arches,tarpaulins,and windproof ropes.The fluid-structure coupling effect of the gas and membrane surface inside the gas ribs,as well as the force characteristics of the windproof ropes,are considered.The deformation and stress of the tent structure are calculated under the combined action of 80 mm snow load and 8-level wind load.The bearing performance of the gas-ribbed inflatable tent structure under the combined action of wind load and snow load is analyzed,and the results show that the appropriate inflation internal pressure of the tent is 300 kPa.
