Experimental and Analytical Investigation on Space Truss

This project describes about the experimental and analytical investigations on space truss with different types of configurations for double layer grid structures such as square on diagonal, square on square offset, square on square offset diagonally, diagonal on square. The Profile stability analyses were done for the above listed configurations for the double layer grid structures using STAAD Pro Version8i software. From the analyses the best among configurations of double layer grid structures space truss were determined and the deflection, axial forces, weight of the truss and pipe section were recorded. The deflection and vibration results of different types of configurations for double layer grid structures space truss were investigated experimentally using Fast Fourier Transform vibration analyzer. From the effective outcome of the results, the structure was designed economically by adjusting the configuration of double layer grid structures with suitable distance. The result exhibits the obvious effect of the load carrying capacity and ductility of DLG space structures.
