Abstract

A compression lap splice may be calculated to be longer than a tension lap splice in high strength concrete according to current design codes. An experimental study was conducted using compressive concrete strengths of 40 and 60 MPa with and without transverse reinforcement, and the effects of compressive strength of concrete, transverse reinforcement, and splice length were assessed. A design equation was derived for compression lap splices with and without transverse reinforcement through regression analysis. For practical purposes, additional provisions were proposed regarding the strength limits of the materials and the arrange- ment of transverse reinforcement. In addition, a simplified equation was suggested for a design code provision.
