Abstract
Abstract A support assembly for a C-beam having a top flange and a bottom flange integrated by a beam web is disclosed. The support assembly has a saddle having a saddle web in engagement with the beam web along a portion of the beam web and a saddle flange supporting the bottom flange. Retaining means connect the bottom flange to the saddle flange. A vertical support member is disposed adjacent the saddle flange and has a free end. Elevating means are on a foundation and are engageable with the free end of the support member to reciprocate the saddle and the C-beam with respect to the foundation. A V-shaped support member has a first support leg and a second support leg terminating in a vee. The vee is affixed to the vertical support member adjacent its free end. The first support leg and the second support leg are connected at first connections to the saddle web adjacent the top of the saddle web to obtain maximum projected bearing area along the saddle flange for the bottom flange, and such legs pass through the shear center of the C-beam to minimize torsion in the C-beam. Further, the first support leg and the second support leg project beyond the saddle web and are connected at second connections to the beam web adjacent the top flange to strengthen the beam web against collapse of the beam web under lateral load.
