Abstract:An equation is developed for the strength of lapped splices of deformed bars in compression. This equation is similar to one previously derived for tension splices and reflects the influence of concrete strength, splice length, bar diameter, and transverse reinforcement. The relative importance of these factors for tension and compression splices is discussed. A comparison shows that current code provisions may require splices 30 percent shorter than calcu-lated by the equation. Development of the equation could lead to an approach to the design of compression splices consistent with that proposed for tension splices.
