چکیده مقاله
Direct Displacement Based Design DDBD is one of the novel approaches for structural design of reinforced concrete frame systems In this study, DDBD approach is investigated for single momentresisting reinforced concrete frame, dual reinforced concrete wall frame and dual steel braced reinforced concrete frame systems In this methodology, first the displacement profile is calculated, following which the equivalent single degree of freedom system is modeled considering the damping characteristics of each member Then, having calculated the effective period and secant stiffness of the structure, the baseshear is obtained based on which the design process can be carried out For each system three frames are designed using Direct Displacement Based Design approach The frames are then analyzed using nonlinear time history analysis with 7 near field earthquake accelerograms In order to reach an understanding of response of the three systems designed using Direct Displacement Based Design, damage index is investigated through lateral drift profile of the models Compatibility of the above mentioned systems with Direct Displacement Based Design approach is also studied via comparison of the nonlinear time history analysis results The results of the analyses indicate efficiency of the DDBD approach for different reinforced concrete structural systems located in near field regions
