Contribuição ao projeto de fundações em radier
The thesis presents a review of the better known design methods for mat foundations and their application to practical cases. The main objective of the thesis is to establish criteria for the computation of internal forces in mat foundations, following a comparative study of the various models and …

Puncionamento de lajes protendidas
In this work it is presented the results of punching tests in three plat slabs. These slabs were supported on a central column and had no shear reinforcement. The parameters varied in them were the prestress applied, the compressive strenght of the concrete and the dimensions of the cross-section …

Cortante longitudinal em vigas de concreto com mesas comprimidas
This work consists of an experimental study about the longitudinal shear problem in beams of reinforced concrete with compression flanges. It is included a brief summary of the design methods and tests published earlier, and also the recommendations of some codes of practice related to the subject. …

Behaviour of reinforced concrete deep beams
… to failure in order to investigate the influence of the following variables on the behaviour of reinforced concrete deep beams : i) Concrete compressive strength ii) Reinforcement iii) Geometry. The model beams were all of 1500mm span, with a depth of 750mm. This span to depth ratio of 2 …

Beam behaviour of hybrid steel sections
Although hybrid beams offer many potential benefits, such as savings in material and costs, existing codes of practice contain few guidelines on how to design such members. Apart from the lack of design guidelines, recommendations in many steel design codes apply only to steel grades with specified …

Quality management in local stonework construction
This study proposes the use of Quality Management as a means of improving the level of quality in local stonework construction. The proposed system integrates provisions to assure quality with those to safeguard the health and safety of the operatives. Several building construction sites have been …

Shear Behavior of Reinforced Concrete Beams and Prestressed Concrete Beams
… high-strength concrete materials are rapid, but codes of practice still limits the concrete compressive strength in design of concrete structures due to a lack of experimental research data. As an effort to overcome the limitation to the use of high strength concrete (HSC) in shear design, an …

Design optimisation of steel portal frames using modified distributed genetic algorithms
… This was achieved by introducing some novelties of the main algorithm of distributed genetic algorithms and applying them in structural optimisation. Among these are the creation of new mutation schemes, adding a crossover scheme, definition of a penalty function, properties of twins, and …

Seismic retrofitting of deficient Canadian buildings
… facing a significant infrastructure crisis. Most of their facilities have been built with little consideration of seismic design and durability issues. As a result, these structures are vulnerable to earthquake loadings and are in urgent need of repair and retrofit. This thesis provides a …

The assessment of corrosion-damaged concrete structures
… are linked together to produce an overview of the effects of chloride-induced corrosion on reinforced concrete structures. The effects of chloride-induced corrosion on the following mechanisms have been investigated: (i) Cracking. (ii) Bond strength. (iii) Flexural strength. (iv) Shear …

The survival of the mandarin tradition in German universities
This thesis studies the professoriate and the overall academic tradition at German universities in context of successive phases of change since 1933. It extends the analysis of the mandarin tradition developed by Fritz K. Ringer in his seminal work entitled The Decline of the German Mandarins. In …

Soul models: rationalization and the art of subjectivity.
In the exchange between theory and practice, art is appropriated as a creative mode of enquiry, a differential form of knowledge and experience in the processes of rationalization. As a differential in knowledge, art is explored as the practice of composition making differences out of established …

Partially prestressed concrete internal square panel
This work is concerned with the general behaviour of an internal panel in a column supported multi-bay floor structure, under the influence of various prestressing tendon arrangements. The prestressing effects are studied with the help of a finite element package (PAFEC), representing the …

Properties and environmental impact from mosaic sludge industry incorporated into fired clay bricks
Brick is one of the most common masonry units used as building material. Due to the demand recently, different types of waste materials have been investigated to be incorporated into bricks. The utilization of these waste materials in fired clay bricks usually has positive effects on the properties …

iPad: A Virtual Studio in my Handbag
Central to this practice-based investigation is the concept that the iPad has the potential to provide the appropriate tools and resources required to create a body of new and original artworks. I suggest that the iPad enables the artist to re-define the concept of an artist’s studio and …

A Critical Evaluation of the Use of Crack Width Requirements in the Durability Design of Marine Reinforced Concrete Structures
… to maximum prescribed values, play a major – and often dominant – role in the design of marine RC structures. However, there are several issues with the current CWRs, chief among which is the fact that, despite decades of research, no clear relationship between crack width and steel reinforcement …
