The aim of present book was to compare the seismic behavior of two bare frame systems and assess the working of shear walls work with moment-resisting frames. Shear walls and bare frames are combined in the first model, while shear walls are absent in the second model and are analyzed statically and dynamically using ETABS 2020 software. The results of two models were compared in different aspects such as base shear forces, displacements and vibration modes.
