Thin walled structures are an important part of engineering construction with territories of use becoming diverse continuously ranging from girder bridges, oil vessels to industrial warehouses , framed structures. Thin walled sections have various stresses and failure modes which can be difficult to predict. Thus structural engineers need help of computers for analysis of these structures. This has been done by using software called THIN-WALL which estimates the cross-sectional properties of the section according to the Vlasov theory. The method of input data for thin walled structure has been explained in this paper. Also the buckling analysis of the thin walled sections has been done using CUFSM which is based on the finite strip method. This method has been explained in the paper and the results the analysis have been compared with the hand calculations according to the Canadian code s-16. The results have been discussed and on basis of this review conclusions have been presented. Cross-sectional Geometry The data is input to the software is similar to the input of a structural frame work software. The thin walled structure is divided into a number elements which intersect at nodes . Each node and element is assigned an number. The coordinates of each node of the cross-section of the member are entered according to any coordinate system chosen . The material properties of the thin walled member such as modulus
