When considering angle members, there is one important behavior or phenomenon which should be addressed or taken into account while determining its tensile capacity. It is nothing but “Shear Lag”, which is the main concentration for today’s article.

Mar 6, 2008 · A flange element that is farther away from the beam takes less compressive stress than a flange element directly over the beam. Shear deformations in the slab relieve some of the compressive stress in elements further from the beam, or ribs. We call that shear lag.

This paper examines shear lag in steel tension members in the following context. First, the background for the current AISC specification provisions is reviewed. Second, the results of an experimental research program in which 27 welded tension members were loaded to failure is …

Aug 27, 2015 · Basically, shear lag is a concept where the forces in a connection require a certain length to properly "get out." This is partially dependent on the relative stiffness of the connection vs. the direction of the application of the load.

Shear lag effects in bolted tension members have been accounted for in the American Institute of Steel Construction (AISC) allowable stress design specification^ (ASD) since 1978.

When some elements of a member are not connected, shear lag may result. Typically, in cross-bracing of trusses and frames (see Figure 1), an engineer determines the geometry, strength and economical design of the connections between major load-carrying members, joined by one or more gusset plates.

Apr 17, 2020 · Shear lag : A non-uniformity of stress in the parts of rolled or built-up sections occurring when a tensile load is not applied uniformly. It is the in-plane shear deformation effect by...

Shear lag is a phenomenon that affects tension members connected at one or both ends through only part of the cross-section. Tensile stresses are transferred from the member into the connected parts and the stress distribution along the connection is …
