Abstract :

Grid shell structures are one of the types of active bending structures, which consist of a network of continuous elements with double curved shells. Therefore, the purpose of this article is the effect of different materials by selecting a sample of mesh shells in improving their structural performance, for this purpose, the geometry of the selected shell was first modeled with the help of Grasshopper program and then using Kangaroo and Karamba physics modeling software in a The repetitive step at the same time, the mechanical and geometric considerations have been analyzed. In the selected sample, with the help of quantitative analytical method in Karamba software, the stresses are calculated, and then, considering the variables of materials with the same thickness and dimensions, which have a rectangular cross-section, to check the amount of displacement in bearing internal forces and stresses that The reason for the change in the weight of the structure has come about, and according to that, the Young's modulus has reached its minimum average, and the steps have been taken. In this way, it can be concluded that among the six different families of materials such as: steel, wood, concrete, steel, composite and polymers depending on the type of access and facilities in each country, polymer structures reinforced with glass fibers and structures Wood has the best structural performance for making grid shells.
