Ultimate capacity of the structure is the maximum base shear that the structure can resist the given load. These ultimate capacity will be changed in varying with Beam size, Beam reinforcement, Column size and Column reinforcement. In this book, it has been clearly shown the effects of these parameters to the ultimate capacity of RC framed Structures with different number of storey. Ultimate Capacity is found from the Pushover Analysis (Non linear Static Analysis). Ultimate capacity has been presented graphically and in tabulated form with changes of various parameters.
