The Performance Investigation of Steel Moment Frames With Knee Braces Subjected to Vehicle Collision

Buildings are always affected by a variety of natural and abnormal forces during their operation. Impact of vehicle collision is an abnormal load which is not usually considered in the design of structures. With the spread of terrorist attacks in many parts of the world, investigation the behavior o...
