• Study on deformed steel columns subjected to impact load due to soft-storey failure in buildings during earthquakes

  Publikacja

  • W. Migda

  - Rok 2013

  The so called soft-storey failure is one of the most typical types of damage induced in buildings as the result of earthquake excitation. It has been observed during ground motions that the failure of an upper soft storey of a structure results in large vertical impact load acting on the lower floors. If the resistance of the structural members of the lower storeys is not sufficient it may further lead to progressive collapse of...
