07-GB Column Bases - FSv ČVUT

7 Column Bases . A Column base consists of a Column , a base plate and an anchoring assembly. In general they are designed with unstiffened base plates, but stiffened base plates may be used where the connection is required to transfer high bending moments. The Column base is usually supported by either a concrete slab or a sub-structure ( a piled foundation). prEN 1993-1-8: 2003 includes rules for calculating the strength and stiffness of Column Bases . The procedure is applicable to columns of both open and closed cross sections [Wald et al, 2000]. Further Column base details may also be adopted, including base plates strengthened by adding steel elements and embedding the lower portion of the Column into a pocket in the concrete foundation. The influence of the support of the concrete foundation, which may be considerable in certain ground conditions, is not covered in prEN 1993-1-8: 2003. Anchor bolts in tension and bending of the base plate Column flange and web in compression Concrete in compression and bending of the base plate Anchor bolts in shear Optional stiffener on both sides a) bolts inside the base plate b) bolts outside the base plate (with optional stiffener).
