PROPOSED MODIFICATIONS TO ACI 318-95 TENSION DEVELOPMENT AND LAP SPLICE FOR HIGH-STRENGTH CONCRETE. DISCUSSION AND CLOSURE

A discussion of a paper with the aforementioned title by A. Azizinamini, D. Darwin, R. Eligehausen, R. Pavel, and S.K. Ghosh, published in this journal (Volume 96, Number 6, November-December 1999), is presented. The discussers question whether the increase in nominal development length recommended by American Concrete Institute (ACI) standard 318-99 is sufficient to ensure adequate ductility or whether the code should also prescribe a minimum amount of transverse reinforcement for normal strength concrete members. Discussion is followed by closure from the authors.
