Dynamic of Structures projects

Time-history and Response Spectrum Dynamic analysis of structures under Step, harmonic and earthquake loading scenarios by numerical MATLAB programming

Description

  • 2015

The project objective was aimed at developing a numerical model for analyzing multi-degree of freedom structures under earthquake acceleration records and user-defined harmonic and step loads. Two multi-story buildings with extreme torsional irregularity were analyzed by ETABS under specific earthquake acceleration records using time-history analysis and response spectrum dynamic analysis methods. Same buildings were programmed and analyzed in MATLAB by numerical methods. Results of numerical models such as mode shape, frequency, modal mass, modal stiffness and time-history and absolutes responses in displacement, shear and moment for each degree of freedom were acquired and verified by making comparison between different methods.
