摘要：Any building structural system should be designed as to ensure
structural stability and resistance for usual loading conditions but also for
potential accidental loading situations. In the case multi-story steel building
frames, the second requirement can be achieved considering special design
situations in case of key structural member loss, such as a column element. In
this case, the behaviour of elements and their connections should be adequate to
avoid structural failure by assuring the development of alternate load paths. In
this paper, a study on beam-to-column end-plate connections with four bolts per
row is presented, in view of enhancing the local behavior of the connection and
also the overall behavior of the new structural system. The study assessed the
viability and behaviour of such connections under extreme loading situations,
where the robustness of the structure represents a critical parameter. It is based
on parametric advanced FEM analyses considering the relevance and impact of
several geometrical parameters.
