ABSTRACT
ABSTRACT: The test series reported here is part of a research program aimed at defining tools for static design of structural elements made of High Strength steel-Fiber Reinforced Concrete (HSFRC). Four-point bending tests have been carried out on 120-MPa (cube strength) beam specimens with a 3.5-m span and a 200 x 300-mm cross section in flexure, and 2.0-m span and 200 x 325-mm cross section in shear. The tests included examination of the minimal shear and longitudinal reinforcement with and without fibers and evaluation of the influence of "short" (35-mm) versus "long" (60-mm) hooked-end steel fibers. The experimental results are compared with various theoretical models with an aim to study and improve the ability to predict the structural behavior of HSFRC members.
