Abstract:

The behaviour of concrete masonry under in-plane compression combined with out-of-plane bending was examined both experimentally and analytically. Ungrouted and grouted masonry, both fully bedded or face-shell bedded, were included in the study. It was found that the masonry under the above stated loading conditions may suffer loss of capacity either due to splitting or shear type of material failure, or by instability. Different loading conditions yield different failure mechanisms, which in turn correspond to different apparent strengths. Theoretical developments are presented leading to es

Abstract:

This research was a step forward to developing data sets for thin layer mortared concrete masonry through systematic experimental and numerical studies. Since thin layer mortared concrete masonry is relatively new type of masonry construction, methodical research studies have been undertaken to properly address the gaps in understanding of this masonry system. As part of the ARC Linkage research project, this thesis has been developed to extend the knowledge on thin layer mortared concrete masonry.

Abstract:

Over 90% of the land area of Turkey lies over one of the most active seismic zones in the world. Hazardous earthquakes frequently occur and cause heavy damage to the economy of the country as well as human lives. Unfortunately, the majority of buildings in Turkey do not have enough seismic resistance capacity. The most commonly observed problems are faulty system configuration, insufficient lateral stiffness, improper detailing, poor material quality and mistakes during construction. Strengthening of R/C framed structures by using cast-in-place R/C infills leads to a huge construction work and

Abstract:

Located on one of the highly active seismic fault systems in the world, the building stock in Turkey is mainly composed of reinforced concrete frames with 4-5 stories. Due to design and construction deficiencies resulting from the use of unqualified personnel and insufficient supervision, many of these buildings lack lateral stiffness, ductility and strength. For many structures, there is a need to alleviate these deficiencies by means of some rehabilitation techniques prior to earthquakes. One approach also used very widely in Turkey is to fill some of the frame bays by cast-in-place R/C pane

Static and dynamic carbonation curing at early age was developed for ordinary Portland cement (OPC) and Portland limestone cement (PLC) concrete masonry units (CMU) production.

Concrete slabs representing the face shell of a 20-cm CMU as well as full sized CMU were used throughout the carbonation process. In static carbonation, it was found that initial air curing was vital to maximize carbonation reaction. After a procedure of casti

Caribbean-style hybrid concrete-masonry structures consist of a reinforced concrete frame with partially grouted and reinforced infill masonry walls. The infill walls are typically connected to the RC frame with cast-in-place dowel reinforcement along one or more edges of the wall. There is limited guidance in masonry codes to design these types of structures, and their seismic performance has not been characterized with experimental tests. In this work, an experimental program characterized the seismic behavior of hybrid concrete-masonry frames and showed they do not exhibit the typical strut

Efflorescence is the presence of insoluble salts upon the surface of concrete or masonry products. The aims of this project were to understand efflorescence and to evaluate metakaolin as an additive for efflorescence prevention. Computer modelling was used in order to simulate the effect of alkali upon relevant phases. Alkali was shown to depress the solubility of calcium hydroxide via the common ion effect, increase, in general, the solubility of calcium carbonate via the foreign ion effect and dramatically increase the solubility and rate of uptake of carbon dioxide into solution.

Due to increasingly stringent requirements on concrete performance and complexity of our infrastructures, concrete with not only high strength but also all-round high performance is called for.

For further advancement of concrete technology into concrete science, it is advocated to adopt a more scientific approach, which can improve our understanding of concrete from a level of “know -how” to a l

The current product is very different from that produced in earlier years having become progressively lighter. At the same time the ratio of the compressive strength to the density has been increased. Improvements in production techniques have made the present day material properties more consistent.

Abstract:

Construction practices are constantly evolving in order to adapt to physical locations and economic conditions. These adaptations may result in more cost-effective designs, but may also come at a cost of strength. In masonry shear walls, it is becoming more common to reduce the amount of grouting from every cell to only those with reinforcement, a practice known as partial-grouting. Partially-grouted masonry responds differently and in a more complex matter to lateral loads as compared to fully-grouted masonry. The response is made even more complex by wall discontinuities in the form of openi

Abstract:

La evaluación de la respuesta dinámica o sísmica de estructuras complejas a menudo requiere de la integración en el dominio del tiempo de la ecuación de equilibro dinámico de la estructura, en el marco de un análisis no lineal. En el caso de estructuras de fábrica y hormigón armado, el uso de este tipo de métodos cobra especial importancia, debido al complejo comportamiento no lineal que presentan, incluso para niveles bajos de carga. Muchas de estas estructuras pueden idealizarse como entramados espaciales de barras. En las últimas dos décadas, se ha desarrollado en la UPC una generalización

Abstract:

This research project is part of a program reviewing the current masonry code NZS 4229: 1986. It involved testing two full-size partially grouted reinforced concrete masonry walls with openings subjected to simulated out-of-plane seismic loading. Theoretical studies were also carried out. The first specimen was C shaped in plan, 904m long, 204m high, with 1.8m long return walls at each end, and there were two doorway openings, one at each end of the main wall. The second specimen plan was the same as the first one, except that there was one door, one middle window and one comer window.. The wa

Abstract:

Unreinforced masonry (URM) walls are often used as load-bearing or infill walls in buildings in many countries. Such walls are also commonly found in existing and heritage buildings in Canada. URM walls are strong structural elements when subjected to axial loading, but are very vulnerable under out-of-plane loads. This type of loading may come from different sources , including seismic or blast events. When subjected to blast, wall elements experience large pressures on one of their faces due to the high pressure produced in the air when an explosion takes place. This wave of compressed air t

Abstract:

Resumo: Diante do grande crescimento da alvenaria estrutural no país, muitas fábricas de blocos de concreto vieram por necessidade, buscar por otimizações do seu processo produtivo, visto que, projetos mais arrojados, acabam exigindo maiores controles de qualidade. A proposta deste estudo é melhorar a produção destes artefatos de concreto por meio de otimizações simples que reduzem o custo e garantem uma produção eficiente na fábrica. Estudar a fundo os vários parâmetros de formação de um traço de concreto seco, tais como coesão, textura, energias de adensamento e resistência à compressão axia
