Structural Behavior Analysis of Gas-Ribbed Inflatable Membrane Structure under Wind Load and Model Test
The gas-ribbed inflatable membrane structure has the advantages of light weight,mobility and convenient construction,and has been widely used in temporary pavilions and hangars.In this paper,the structural forms of gas-ribbed inflatable membrane structure are analyzed through a literature review.Then,taking strip-cage type structure as the research object,the common node model is established to analyze the influences of diameter,number of braces,and internal pressure on the wind load effect of the structure.At the same time,the effects of various cables are clarified by deleting them from the model.Finally,the loading test of the inflatable arch is carried out,and the test results are compared with the results of the finite element calculation.
