Abstract:
Design charts are very useful for fast determining the percentage of reinforcement for singly and
doubly reinforced concrete beams having known cross-sectional dimensions, characteristic
strengths of the concrete and steel, and the ultimate design moment. A complete set of design
charts is given in BS: 8110 - 85: Part 3, but it seems difficult to use these charts especially for
doubly reinforced beams. In this paper, a straight-forward design chart has been developed based
on BS: 8110 – 97 design rules. Several design examples have been solved using the developed
chart and good results have been obtained.
