Ductile and partial-strength steel & composite joints as basis for redundant and robust frame structures

Abstract

▪ The paper highlights the ductility demand of beam-to-column connections in the framework of progressive collapse assessment of framed steel or composite structures considering sudden column loss due to e.g. impact, blast, etc..

▪ There are different design approaches to achieve the mitigation of progressive collapse. One method of achieving this goal effectively is the redundancy approach (alternate load path method). The redundancy approach is well suitable for structural steel buildings with inherent sufficient ductile material behaviour allowing deformations when local failure occurs. [extract from description]
