Abstract: The purpose of this study is to investigate the effect of hook shape and material of high tensile strength hooked end steel fibres and the impact of cement replacement materials on pullout behaviour of steel fibres from cementitious composites. The cement replacements which have been used in this research included silica fume, pulverised fuel ash, limestone filler and ground granulated blast-furnace slag. In total, more than 800 samples have been manufactured for experimental research on compressive strength and pullout behaviour of hooked end steel fibres from cementitious matrices. The effects of parameters such as water/binder ratio, cement replacement content, age of sample, hooked end shape and tensile strength of fibre on fibre–matrix pullout behaviour were determined. The results of tests and analysis indicate that hook shape, tensile strength of fibre and silica fume affect the maximum pullout force and ground granulated blast-furnace slag can significantly improve the residual

Abstract: Modelling of human-induced loads has been proved to be very difficult as we can see in several approaches of varying complexity that have been presented in the literature. Crowd induced dynamic loading in large structures, such as gymnasiums or stadiums, is usually modelled as a series of harmonic loads which are defined in terms of their Fourier coefficients. Different values of these Fourier coefficients that were obtained from full scale measurements can be found in codes. In this paper, a study of loads generated by different human actions (jumping, walking and dancing) is presented. A comparison between experimental data measured with instrumented insoles and numerical data obtained with numerical models has been carried out. Tests have been performed on a structure designed to be a gymnasium, which has natural frequencies within that range of the excitation frequencies.
