Compress

The purpose of this research is to analyse the available design equations and present the applicability of these equations for their use in the design of beams made of higher concrete strengths. In the present program concrete having compressive strength of 50MPa or more is considered as high strength concrete. Analytical investigation on HSC beams is made under four different aspects namely flexure, ductility, deflection and shear.

Tensegrity is a structural system constructed of tensile cables and compressive bars. This thesis proposes several general methods for creating tensegrity structures. The author has developed new methods for creating specific tensegrity cells and the corresponding computer code. Furthermore, the author has constructed various physical models to validate the methods. A proposal for an observation tower on top of the Eureka building in Melbourne has also been devised by the author.

The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.

The fatigue failure around rail-end-bolt holes is particularly dangerous since it leads to derailment of trains and consequently to inevitable accidents. It is well-known that the fatigue life of structural holed components, subjected to cyclic load, can be increased by generating compressive hoop stresses around the holes.

This thesis proposes a new method to determine moving objects by applying some motion estimation techniques in the video compression domain. At the same time, this method will also be used to build an application that supports the identification and search of motion in home surveillance videos. The compression format of the videos in the thesis uses H264 compression (MPEG-4 part10), a popular video compression standard today.
