Shear Wall

SHEAR WALL (http://www.engpedia.com/index.php/Shear_Wall) IS A STRUCTURAL ELEMENT USED TO RESIST LATERAL/HORIZONTAL/SHEAR FORCES PARALLEL TO THE PLANE OF THE WALL BY:

CANTILEVER ACTION FOR SLENDER WALLS WHERE THE BENDING DEFORMATION IS DOMINANT
TRUSS ACTION FOR SQUAT/SHORT WALLS WHERE THE SHEAR DEFORMATION IS DOMINANTConcrete Shear Walls (http://www.engpedia.com/index.php/Shear_Wall)

A shear wall in a structure absorbs lateral forces to stabilize the walls perpindicular to it. Like in a Garage for instance, you typically have no interior walls to absorb the lateral forces in the building to keep them from leaning, so the corners of the exterior walls have to be sheathed and fastened to the concrete according to certain specs (depending on location, wind, siesmic differences) to absorb these loads. In most buildings though there are interior walls perpendicular to the exterior walls that can be used to absorb these shear or lateral forces.

There are thousands....We in the UK have more than enough..

Lag bolts, and sometimes, depending on the load rating, epoxy glues.

All the answers I read are correct, but they are missing a simple fact. You need to make sure that the anchors that you are using are rated for the weight you intend to use them for. This has to take into account the weight of the beam and anything you hope to put or hold up with that beam.
