Analysis and Evaluation of Bearing Capacity for an inflatable membrane
Based on an existing inflatable membrane structure,the key inspection points and the method of bearing capacity evaluation are introduced.The control point,inflatable system,membrane performance,metal components and connections of the inflatable membrane struc-ture were inspected on site.The result showed that the configuration of connection between the cable and the reinforced concrete supporting member did not meet the requirements of the current code and the corresponding strengthening measures should be adopted.The finite ele-ment software 3D3S was used to check the bearing capacity of the inflatable membrane structure at the basis of inspection data and the re-sults indicated that the structure satisfied the code requirements including the bearing capacity and deformation.The method provided in this paper can be adopted for other similar engineering.
