Numerical investigation of the behaviour of bolted and welded top and seat angle connection in progressive collapse of steel structures [PDF]
Journal of Structural and Construction Engineering, 2019 After failure of a column in structure by an abnormal loading, undesirable performance and damage of connections of the beams connected to the top of this column, can lead to the local failure of floor and in turn result in progressive collapse in the ...

Behaviour of precast concrete beam–column sub-assemblages subject to column removal [PDF]
Engineering Structures, 2015 Abstract Under column removal scenarios, initiation of alternate load paths via adjacent bridging beams to redistribute vertical loads requires certain level of ductility and continuity in beam–column joints. Although this approach does not consider the magnitude of the blast event, it is threat-independent and offers a minimum level of robustness ...
