Numerical assessment of T-stub component subjected to impact loading

摘要

Since the partial collapse of the Ronan Point building in London in 1968, requirements for the avoidance of disproportionate, collapse are addressed in the design codes. Despite these prescriptive requirements, the ability of steel connections to sustain large tensile forces whilst undergoing significant rotations has been questioned by recent studies and real evidences (as for example, the collapse of the World Trade Center in 2001).
