JOINT STRUCTURE FOR A COLUMN AND BEAM COMPRISING YIELDABLE PORTIONS
A building framework includes plural column assemblies (26) supporting plural beams (24) supporting floors of the building, with the union of the column assemblies and beams forming beam- to - column (or beam- to - column - to -beam) joint connection assemblies (28) according to this invention. The joint connection assemblies inventively include novel features which remarkably and surprisingly improve the distribution of strain and plastic deformation in the joint connection structure when subjected to extreme load challenges to the building structure (as may occur during earthquake, explosion, progressive collapse load conditions, or massive impact). These novel features include a joint connection structure comprising a cover plate with a yieldable portion comprising a yieldable tongue wherein the joint connection structure plastically deforms during extreme cyclic movements.
Cette invention concerne une charpente de bâtiment, comprenant une pluralité d'ensembles de poteaux (26) supportant une pluralité de poutres (24) supportant des planchers du bâtiment, l'association des ensembles de poteaux et de poutres formant des nuds d'assemblage de poutre à poteau (ou de poutre à poteau à poutre) (28). Les nuds d'assemblage de l'invention comprennent des caractéristiques nouvelles qui améliorent remarquablement et de manière surprenante la distribution des contraintes et de la déformation plastique dans la structure d'assemblage quand la structure de bâtiment est soumise à des sollicitations de charge extrême (comme cela peut arriver pendant un tremblement de terre, une explosion, dans des conditions de charge progressive d'affaissement, ou lors d'un impact important).
