Analysis of the design concept of membrane structure carport

Membrane structure is a new type of material, developed in the middle of the 20th century, a new architectural structure form, it is made of a variety of high-strength film materials and strengthening components through a certain way to produce a certain amount of pre-tension stress inside to form a certain shape of space.

1. Find a shape of initial balance;

2. Mechanical analysis under various load combinations to ensure safety; So far the finite element method has been widely chosen. The element types are triangular plane constant strain elements.

3, cutting and manufacturing. The membrane structure transplanted from the theory of large deformation of rigid plate and shell as only tensile soft shell is not suitable for the selection of this plane unit because of the rigid shell, it can be seen from the analysis. The flat plate element can be regarded as a combination of plane stress element and plate zigzag element, and the element matrix can be merged by the two elements. The membrane structure, as a soft shell, can not be bent only by the curvature of the film surface, and then lead to the redistribution of internal forces on the membrane surface to resist the external load perpendicular to the surface.
