This study presents an analytical approach for seismic assessment of RC frames using nonlinear time history analysis and push-over analysis.
The research provides the necessary building blocks for developing efficient nonlinear time history models of buildings framed from cold-formed steel.
To check the effectiveness of the device in mitigating the responses of multi-story frames, several nonlinear time history analyses were conducted on the structures using three earthquake excitations.
After justification of the modeling results by the experimental measurements from various loading conditions, the proposed model was applied in nonlinear time history analysis for steel frames using fiber beam element method.
Nonlinear time history analyses of the frames were performed using scaled ground motions.
The financial risk assessment is determined on the basis of results of incremental dynamic analysis (IDA) of reinforced concrete frames analyzed using nonlinear time history analyses on IDARC platform with a suite of 20 ground motion records used by Vamvatsikos and Cornell (2002) for mid-rise buildings.
For the nonlinear time history analyses of the plane frames, 7 seismic ground motions (Chi-Chi, Tabas, Kocaeli, Kobe, Northridge, Imperial Valley and Loma Prieta) were chosen from the Pacific Earthquake Engineering Research PEERR) database.
The performance of the optimal frame is verified by nonlinear time history and fragility analysis.
Nonlinear time history analyses are conducted on these braced frames to obtain seismic demands under both design and maximum considerable levels of earthquake motions and near-field motions.
For this purpose, in this study we present nonlinear time history analyses of multi-story reinforced concrete frames under observed and synthetic records of a particular earthquake.
