Abstract

The resistance as well as strain hardening and softening properties of UHPFRC depend on the type of matrix and mainly on the fibre dosage and final distribution and orientation in the element. The strength and deformability distribution in a thin UHPFRC panel was studied. Tensile and flexural specimens cut in different directions and at different positions in the panel were analysed in order to determine locally the mechanical material properties. The real fibre dosage, distribution and orientation were determined. The results showed a wide scatter of the mechanical properties, whereas the physical properties, especially the air permeability, were not affected by the mechanical scatter.

Strength of materials

The field of strength of materials (also called mechanics of materials) typically refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus, and Poisson's ratio.

Ultimate tensile strength

Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or in notation) is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials the ultimate tensile strength is close to the yield point, whereas in ductile materials the ultimate tensile strength can be higher. The ultimate tensile strength is usually found by performing a tensile test and recording the engineering stress versus strain.

Ratio distribution

A ratio distribution (also known as a quotient distribution) is a probability distribution constructed as the distribution of the ratio of random variables having two other known distributions. Given two (usually independent) random variables X and Y, the distribution of the random variable Z that is formed as the ratio Z = X/Y is a ratio distribution. An example is the Cauchy distribution (also called the normal ratio distribution), which comes about as the ratio of two normally distributed variables with zero mean.
