Analysis of Nonlinear Seismic Response of Reinforced Concrete Frame-Wall Structures

The inelastic response of reinforced concrete plane frame-wall structures subjected to strong ground motions is studied from an analytical standpoint. In the analysis, the structure is idealized as the assemblage of prismatic members with two rigid zones at its ends. The influence of mombers' moment-axial force interaction effects, slippage rotation at the ends of these members due to non-perfective bond of renforcing bars and geometric nonlinearities (often known as "p-Delta" effects) are considered in this method. The numerical results show that the presented method and programed code are very effective in computing CPU time and storage. With the technique proposed, analysis of nonlinear seismic response of large tall building structures can be carried out in a micro-computer,and it is very satisfactory in explaining earthquake hazerds of building structures and predicting the possible damages.
