Ceram Publishes Extended Guidance on the use of Bond Beams and Columns to Resist Lateral Load

Ceram has published the Design Guide for Masonry Reinforced by Bond Beams and Columns to Resist Lateral Load, to supersede the original which covered the use of bond beams only.

The Guide is the result of a four-year research and test programme to evaluate reinforced, full-size walls strengthened against lateral load and provides guidance and recommendations for the design of masonry walls incorporating bond beams and columns.

The Guide expands upon the guidance in BS 5628 and EC6, and was validated through the extensive testing and analysis performed at the Ceram laboratories; the results have been published internationally.

Traditionally, large span single leaf concrete blockwork walls that are subjected to significant wind loads are subdivided by the use of wind posts. However, a new more state-of-the-art system has been devised for masonry walls. In the new system, the vertical span is split through the introduction of horizontal reinforced bond beams that span between the main structural columns at intervals up the wall height. Shear transfer rods, an innovative method of providing additional support for walls, ensure the courses above and below the bond beams act compositely. Horizontal spans are similarly subdivided by vertically reinforced hollow blocks which are concreted to form bond columns.

Dr. Geoff Edgell, Principal Consultant, Construction at Ceram commented: "In a period when newly introduced Eurocodes for design will not be amended for a few years whilst they ‘bed in', it is encouraging to see that an innovative development can gain acceptance in the market place through the publication of an independent Design Guide. The original Guide provided a basis for the wall designs of the East London Goods Terminal at the Kings Cross Railway Station development, while the extended Guide has supplied the basis for the walls of the 2012 Olympic Games Aquatics Centre."
