Concrete Toronto

In the sixties, architecture fell in love with concrete. Architecture has since shifted its fondness to glass and steel, and concrete buildings have fallen out of favor and into disrepair. But they represent an exciting era of faith in architecture and technical innovation that has yet to be documented.Concrete Torontoacts as a guidebook to the city's extensive concrete heritage. Architects, journalists, professors, concrete experts, and even the original architects use a wealth of new and archival photos, drawings, interviews, articles, and case studies to celebrate Toronto's concrete past.

Concrete progress deals with the technology that made concrete the most widely used building material in the world in the course of the past hundred years, and the most indispensable for the global socio-economic development in the new millennium. It offers an insight into many people's dedicated, exploratory concrete research, and into strategic planning and management of research and its transfer to engineering practice. This book is introduced by retrospectively highlighting the international history of concrete technology and uses.

Elevated temperatures are known to affect the properties of both fresh and hardened concrete. This book describes in detail these effects and explains the mechanisms involved with particular reference to their practical aspects.

The present doctoral thesis was developed within the framework of the research project "Deformation Capacity of Structural Concrete". This project aims at developing a consistent and experimentally verified theory of the deformation capacity of structural concrete. Previous work included the development of a theoretical model, the so-called Tension Chord Model, which allows a comprehensive description of the load-deforma tion behaviour of tension members in non-prestressed and prestressed concrete struc tures. The present work focuses on a new theoretical model, the so-called Cracked Mem brane Model. For members subjected to in-plane forces this new model combines the ba sic concepts of the modified compression field theory and the tension chord model. Crack spacings and tension stiffening effects in cracked membranes are determined from first principles and the link to plasticity theory methods is maintained since equilibrium conditions are formulated in terms of stresses at the cracks rather than average stresses between the cracks. The research project "Deformation Capacity of Structural Concrete" has been funded by the Swiss National Science Foundation and the Association of the Swiss Cement Pro ducers. This support is gratefully acknowledged. Zurich, July 1998 Prof. Dr. Peter Marti Abstract This thesis aims at contributing to a better understanding of the load-carrying and defor mational behaviour of structural concrete subjected to in-plane shear and normal forces.

Provides a thorough review of properties, durability and use of high performance concrete, derived from recent research and experience. This book contains contributions from the leading French, Canadian and Swiss researchers, designers and material specialists, translated into English for the first time.

Many contemporary building projects use pliant and economical concrete as their main structural material yet its use requires technical expertise, knowledge and experience. This book analyses 12 projects which cover both the practical and aesthetic aspects of the subject.

Concrete repair continues to be a subject of major interest to engineers and technologists worldwide. The concrete repair budget for the UK alone currently runs at some UKP 220 per annum. Some estimates have indicated that, worldwide, in 2010 the expenditure for maintenance and repair work will represent about 85% of the total expenditure in the construction field. It has been forecast that, in the same year in the USA, 50 billion dollars will be spent just for the restoration of deteriorated bridges and viaducts. An understanding of the latest techniques in repair and testing and inspection is thus crucial to the international construction industry. This book, with contributions from 34 countries, brings together the best in research, practical application, strategy and theory relating to concrete repair, testing and inspection, fire damage, composites and electro-chemical repair.

Exploring Toronto’s history through the stories of its most fascinating and shadowy deaths. If these streets could talk... With morbid tales of war and plague, duels and executions, suicides and séances, Toronto’s past is filled with stories whose endings were anything but peaceful. The Toronto Book of the Dead delves into these: from ancient First Nations burial mounds to the grisly murder of Toronto’s first lighthouse keeper; from the rise and fall of the city’s greatest Victorian baseball star to the final days of the world’s most notorious anarchist. Toronto has witnessed countless lives lived and lost as it grew from a muddy little frontier town into a booming metropolis of concrete and glass. The Toronto Book of the Dead tells the tale of the ever-changing city through the lives and deaths of those who made it their final resting place.
