Abstract
This paper compares and verifies the experimental membrane device with the model created in FEM software. At first, the experimental device needs to be properly set up and prepared. This includes settings of all input factors such as the placement of the technical fabric, the pretensioning of the edge ropes, the functionality of the actuators or load cells placed on the anchor rods. The numerical model in FEM software was created to confirm the functionality of the experimental device. Based on the results obtained by simple load cells measurements and the load results in the numerical model, it was confirmed that the behaviour of the experimental device coincided with the assumed behaviour of the membrane structure.
Highlights
Over the last century, major developments are happening in almost every part of industry
The differences in the values of the forces measured on the experimental device and in the numerical model represent maximum difference of 8,042%, which is an acceptable value, and so we can say that the implemented equipment coincides with the theoretical model in terms of behaviour
We can say that based on these results, the real construction acts more rigidly than the computational model, which is more appropriate in terms of safety
Summary
Major developments are happening in almost every part of industry. Experimental research and development centres try to respond flexibly to this need for development and requirements This implies that a wide range of different investigations, experiments and tests must be carried out to ensure the complete stability and safety of any structure before introducing new one into construction practice. The aim is to simulate a lot of different situations and conditions that can lead to unfavourable conditions and affect the specimen in the worst possible way Such processes require a lot of time and effort, space and equipment, and last but not least, the need to ensure sufficient capacities of various experts and specialists [1]. Membrane constructions only work in tension and their specification is to find the correct prestressed shape called form-finding
