The models presented in this thesis featured special modelling techniques and were able to predict all types of failure modes such as bearing, net area fracture, shear yielding, flexural yielding, and weld tearing of the connections. However, the effect of axial forces on the shear tab’s performance has only recently been the subject of study.

Generally, the stability of structures is calculated by the use awsemblages recommended temperature-time curves that do not considered the cooling phase of the biulonns. This preliminary step is essential for an optimised design of connections in similar conditions.

The reduction of steel mechanical properties and restrained thermal deformations induce a new distribution of internal forces in the frame. Standard Standard de boulons. A series of four full-scale tests were performed on shear tab connections between a Wx beam and a W x column, as well as a W x 60 beam and a W x column.

Secondly, a set of parametrical analyses have been performed in order to better understand the influence of several factors on the induced internal forces and provide some reference results for the last part of the work. Afficher longueur de recherche comme lignes temporaires Cette option est disponible dans le composant Boulon auto. Ecartement entre les boulons, dans la direction y du groupe de boulons. Previous finite element modelling of shear tabs lacked damage simulation capability, did not include the effect of weld tearing, and as such often overestimated the connection resistance.

The results from these tests and previous shear tabs tested under gravity load alone were used in the development of a finite element model that is capable of simulating the response of the connection under shear load; predict the ultimate resistance and the progression of failure.

When a constituent of a frame is subjected to fire, the thermal dilatation and bowing of this element is limited by the action of the surrounding frame. Quick feedback Did you find what you were looking for?

Numerous laboratory test programs of these connections subjected to vertical loading alone have been completed over the past 30 years.

Each rebar set modifier only affects those rebar set reinforcing bars that its projection touches. The main objective of the research program described dew was to develop a design approach that could be used by the engineering community to address the effect of combined axial and shear force on a shear tab connection.
