Analytical Aspects of Velocity Pulses on Seismic Behaviour of Mid-Rise Compound Skeleton of Steel Moment Frame and Eccentrically Braced Panels

Steel moment frame and bracing panels compound structures are suitable systems for medium-height resistant skeletons due to their desirable ductility along with high rigidity when facing large dynamic forces caused by earthquakes. In this research, the seismic behavior of two 10-story buildings with...
