Finite Element For Analysis Of The Multi-ribbed Lightweight Wall Panel Frame Of Space Computational Model

Lightweight frame structure of multi-ribbed wall panel is a new type of structure, which lightweight, big rigidity, good anti-seismic capacity, to economize energy resource, good social benefit and green environment protection are different from ordinary frame and shear wall. Because of its particularity, today there is not better-rounded theory and analysis method. In this paper, load carrying mechanism, lateral displacement, and design and calculation procedure of lightweight frame structure of multi-ribbed wall panel are studied with chief achievements as follows:Based on the test, which a ten-story building model of lightweight frame structure of multi-ribbed wall panel with ratio 1:3 is studied though the pseudo-dynamic test, the wall is considered as a plane compound substructure, and space frame-plane compound substructure computational finite element model is given. Numerical value analyses are done with ratio 1:3 building model.In addition, for practical analysis and calculation the wall is considered as equivalent compressive diagonal strut and equivalent concrete wall, and space frame-compressive diagonal strut computational finite element model and space frame-concrete wall computational finite element model are given in this thesis.Finally, a space finite element program in MATLAB is worked out with computational results that turn out to coincide well with the test results.
