CONSTITUTIVE MODELING OF STEEL FIBER REINFORCED CONCRETE UNDER DIRECT TENSION AND COMPRESSION. FIBRE REINFORCED CEMENTS AND CONCRETES: RECENT DEVELOPMENTS. PROCEEDINGS OF AN INTERNATIONAL CONFERENCE HELD AT THE UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, UNITED KINGDOM, SEPTEMBER 18-20, 1989

Experimental results and analytical simulation techniques were used to develop predictive equations for the strength and complete stress-strain relationship of steel fiber reinforced concrete (SFRC) under direct tension and compression. The developed equation for tensile strength accounts for the contributions of fibers through their pull-out action and also by arresting the growth of microcracks in cementitious matrices. The modeling of post-peak performance in tension has been based mainly on the results of pull-out tests on single and multiple fibers which were aligned or inclined with respect to the pull-out directions. The developed equations for compressive strength and stress-strain relationship are simple and practical, and they account for the improvements in concrete ductility and energy absorption capacity in compression resulting from steel fiber reinforcement. The developed constitutive models compare satisfactorily with experimental results, and they can be used as practical tools for analytical investigations on steel fiber reinforced concrete.(A) For the covering abstract of the conference see IRRD 827953.
