Experimental and theoretical investigation of a three-way double-layer space grid system truss / Mohd Suhaimi Rafie

This project report contains. the theoretical and the experimental investigation of a three-way double-layer space grid system truss. In the theoretical analysis, computer program. The programs were based on Stiffness Method and Plate Analogy with regard to Prof. D.T.Wright's
paper. Both programs were developed on the assumption that the joint has a pin effect. The program developed in Method of offers the solution for any pin-jointed structure. In other method, the program was developed for a double-layer space truss. In the experimental investigation a model of a three way double-layer space grid system was set up. The measurements of forces in selected members and the vertical displacements at selected joints were carried out by the used of Btrain gauges and dial gauges respectively.
