Function comparison between moment frame and moment frame with centrically braces in high-rise steel structure under the effect of progressive collapse

Steel moment system and steel moment with centrically braces are two common systems. Many of regulations related to this structures explained in details to design structures against earthquake loads but they didn’t mention methods about dynamic load such as blast or car crash. However, the mentioned...
