The Effect of strong motion duration on pounding of steel moment frame building

Usually during moderate and strong earthquakes, if the space between the adjacent structures is not enough, structural pounding will occur which is due to the out-of-phase vibration of the structures regarding the differences in dynamic properties of the structures. Different factors contribute in t...
