Design rules for stress development by end anchorage or lap splicing are fundamentally important when detailing deformed steel reinforcing bars in concrete structures. They determine the amount of additional steel required to maintain the effectiveness of tensile or compressive bars, and thus can significantly affect detailing and economy. A recent survey of the typical standard tables of minimum development and lap splice lengths for straight D500N bars included by different consulting engineering companies on their general notes structural drawing showed relatively large variations in values for the same design options, when determined using the development length formula in AS 3600-2001. Development length and lap length have often been assumed equal despite the effect clear distance “a” between planar parallel bars developing stress can have in the formula, which should have included upper and lower bounds on “a”. With the advent of AS 3600-2009, new formulae are provided for computing basic or refined development or lap lengths, which incorporate new design variables and factors that account directly for transverse pressure and/or reinforcement, and whether or not lapped bars are in contact with each other, staggered, or in regions of high or low tensile stress. Therefore, the need is even greater to assist consulting engineers to develop accurate, condensed design tables. Comprehensive sets of general, bar-cover-controlled and bar-spacing-controlled design tables are developed in accordance with AS 3600-2009, and their application to general design problems is demonstrated. A unified approach for preparing project-specific design tables and notes for structural drawings is also described.
