Abstract:

The purpose of this thesis is to study the behavior of the particular building system that makes use of load-bearing walls of reinforced concrete cast into mineralized wood. This construction system has been studied under the action of pseudo-static forces (experimentally and numerically) and under dynamic forces (only numerically). The activities carried out, in general, employed experimental equipment for the realization of tests on materials and on specimens that can be both portions and real scale walls. Additionally, a commercial software has been used for the numerical modeling of the el

Abstract:

The global warming has increased with unprecedented levels during the last couple of decades and the trend is uprising. The construction industry is responsible for nearly 10% of all carbon emissions, mainly due to the increasing global population and the large demand for housing and civil infrastructure. Concrete, which is the most used construction material worldwide, is found in every type of building as it provides long term structural stability, support and its main constituent cement, is very cheap. Consequently, due to the raising concerns of high average temperatures, the research comm

Patented by Joseph Monier in 1867, reinforced concrete became a highly successful material during the 20th century, capable of satisfying the most challenging demands of designers and engineers. However, even though its introduction in construction paved the way for a century of continuous technological innovation in the building industry, the mechanical behaviour of structures made with this material has not been fully understood for a long time, giving rise to a variety of structural problems of the buildings built in the first decades of the 20th century.

Abstract:

Concrete, the second most used material in the world, presents great performance and economic benefits. Yet, it is often characterized by a brittle behaviour, low tensile strength, and toughness. Fibers are usually added to concrete to counteract its brittle behaviour, increasing ductility and toughness, controlling crack propagation and delaying concrete failure. However, their addition significantly worsens the fresh state performance of the material. To improve fresh state of the so-called Fiber Reinforced Concrete (FRC), conventional mix-design methods recommend the use of high paste conte

Concrete repair materials are being widely used to restore and extend the service life of structures.

Amongst other factors, concrete permeability and chloride diffusivity within concrete are believed to play a major role in determining the durability and success o

SHCC contains randomly distributed short fibres which improve the ductility of the material and can resist the full tensile load at strains up to 5 %. When SHCC is subjected to tensile loading, fine multiple cracking occurs that portrays a pseudo strain hardening effect as a result. The multiple cracking is what sets SHCC aside from conventional Reinforced Concrete (RC). Conventional RC forms one

The 28-day shear strength measurements showed an increase in rebar-concrete bond strength as the water to cement ratio (w/c) was reduced from 0.50 to 0.40 for both fly ash containing and non fly ash control sam

碩士<br>國立屏東科技大學<br>土木工程系所<br>97<br>This study used the pulsed thermography of infrared thermography technology to heat reinforced concrete (RC) specimens, and then used an infrared thermography meter to record the heat dissipation history on specimens of different water-cement ratios WC. The data was used to formulate a best model to evaluate the WC of concrete. The model was then applied on a RC construction for verifying its feasibiltiy. The factors influencing the measurement values were discussed as well. Furthermore, the evaluated WC was also substituted into a Kishitani formula to calcula

Abstract:

Concrete is the most widely used material in the world for construction of infrastructures and there are quite a few gaps in understanding its behaviour under different loads. Fracture in concrete occurs at pre-existing crack tip upon the formation of a fracture process zone (FPZ) with several toughening mechanisms such as micro-cracking, aggregate bridging, crack branching etc., taking place resulting in energy dissipation, which resists further crack propagation. This FPZ is responsible for the post-peak softening response under tension and size effect. The behaviour of reinforced concret

abstract: The main objective of this study is to investigate the behaviour and applications of strain hardening cement composites (SHCC). Application of SHCC for use in slabs of common configurations was studied and design procedures are prepared by employing yield line theory and integrating it with simplified tri-linear model developed in Arizona State University by Dr. Barzin Mobasher and Dr. Chote Soranakom. Intrinsic material property of moment-curvature response for SHCC was used to derive the relationship between applied load and deflection in a two-step process involving the limit stat

Abstract:

Tese de Doutoramento (Programa Doutoral em Engenharia Civil)<br>Recent research is showing that the addition of Recycled Steel Fibres (RSF) from postconsumed tyres can decrease significantly the brittle behaviour of cement based materials, by improving its toughness and post-cracking resistance. In this sense, Recycled Steel Fibre Reinforced Concrete (RSFRC) seems to have the potential to constitute a sustainable material for structural and non-structural applications. To assess this potential, experimental and numerical research was performed on the use of RSFRC in elements failing in be

Abstract:

"Dry-stack masonry (DSM) systems are developed in response to rising labour costs. Generally DSM is constructed using concrete blocks without mortar joints. These systems use different methods of achieving structural integrity. Grout and reinforcement are used in some systems and post-tensioning (unbonded tendons) are used in some other systems to achieve bonding through various interlocking mechanisms. This thesis describes the development of an Australian patent pending DSM walling system that uses special featured interlocking blocks. Surface redering using a special fibre reinforced cement

Abstract:

Crack propagation in structures when subjected to fatigue loading, follows three different phases namely - short crack growth, stable crack growth and unstable crack growth. Accurate fatigue life prediction demands the consideration of every crack propagation phase rather than only the stable crack growth stage. Further, the use of existing crack growth laws in structures with small cracks under-predicts the growth rate compared to experimentally observed ones, thereby leading to an unsafe design and keeping the structure in a potentially dangerous state. In the present work, an attempt is mad
