Abstract
This paper presents an overview of the research on the flexural behavior of HSC
members. The study has resulted in the identification of factors that affect the
flexural behavior and design of reinforced concrete members made of HSC. The
paper also identifies relevant design issues to extend the current concrete
compressive strength limit of about 85 MPa in the Romanian code and EC2
design specification
Keywords: beam, flexural members, high strength concrete.
1 Introduction
Revolutionary evolutions related to novel materials of construction and
modifications and improvements in the behavior of traditional materials have
taken place in recent decades. The 21st century definitively will be the
millennium of high performance and high strength concrete because the
application of the strength concrete in the design of various engineering
structures is being constantly increased in different parts of the world.
High-strength concrete is a brittle material and its brittleness increases
proportionally with an increase of its strength. It is necessary to provide a greater
ductility of elements of HSC in order to apply them in seismic prone areas.
The study report in this paper mainly investigates the implications of using
HSC in reinforced concrete flexural members.
2 Experimental program
The experimental program contained a number of twelve simple reinforced
concrete beams, tested at bending. The beams were realized with concrete with a
mean compressive strength of 85MPa, with a constant length of L=3200mm and
