Recently, composite columns are finding a lot of usage for seismic resistance. In order to prevent shear failure of RC column resulting in storey collapse of building, it is necessary to make ductility of columns larger. Recently, most of building utilizes this Concrete Filled tubes (CFT) concept as primary for lateral load resisting frames. The concrete used for encasing the structural steel section not only enhances its strength & stiffness, but also protects it from fire damages Columns occupy a vital place in the structural system. Weakness or failure of a column destabilizes the entire structure. Strength & ductility of steel columns need to be ensured through adequate strengthening, repair & rehabilitation techniques to maintain adequate structural performance. Where the gj's are properly chosen continuous functions of one variable, and the ij's are continuous monotonically increasing functions independent of f. Any continuous real-valued functions f (x1, x2, ..., xn) defined on[0, 1Jn, # =2, canbe represented in the form An elementary neuron with R inputs is shown below. Each input is weighted with an appropriate w. The sum of the weighted inputs and the bias forms the input to the transfer 2.4 Train the Network Fig4. 200T Cyclic Testing Machine 6.
