This volume traces the process by which reinforced concrete emerged during the 19th century as the successful building material of today. Early work on testing the strength of cements led into a period of experimental work by a number of engineers, notably in Britain, France and America, to devise successful systems of embedding iron in concrete in such a way that the two materials would act together to carry imposed loads. The papers take the story to the early years of the 20th century and provide a thorough review of the gradual evolution of ideas and the contributions of individuals to this technology.
The average lifespan of a house is somewhere around 100 years. During that time it will see many mutations in household composition and related spatial rituals. Designers are therefore faced with the task of giving form to something that is constantly subject to change. Many studies into flexibility focus on the changeable, on movable partitions and variation in the internal layout. The present study takes not the changeable but the permanent as its departure-point. The permanent--i.e. the more durable component of the house or building--constitutes the frame within which change can take place, while the frame defines the generic space, the space in which change can occur.
This volume covers the second great period of developments in iron construction from 1850, following its establishment as a structural material described in volume 9 of this series. Using the Crystal Palace of 1851 as a starting-point, the papers trace the history of iron-frame construction in Britain, France and America, and show its importance in fireproof construction, and in lattice truss and arch bridge design. A final group of papers illustrates the emergence of steel in framed buildings in both Britain and America. The selection brings out the important and daring contribution of individual engineers in their use of this material.
Physical models have been, and continue to be used by engineers when faced with unprecedented challenges, when engineering science has been non-existent or inadequate, and in any other situation when the engineer has needed to raise their confidence in a design proposal to a sufficient level to begin construction. For this reason, models have mostly been used by designers and constructors of highly innovative projects, when previous experience has not been available. The book covers the history of using of physical models in the design and development of civil and building engineering projects including bridges in the mid-18th century, William Fairbairn?s Britannia bridge in the 1840s, the masonry Aswan Dam in the 1890s, concrete dams in the 1920s, thin concrete shell roofs and the dynamic behaviour of tall buildings in earthquakes from the 1930s, tidal flow in estuaries and the acoustics of concert halls from the 1950s, and cable-net and membrane structures in the 1960s. Traditionally, progress in engineering has been attributed to the creation and use of engineering science, the understanding materials properties and the development of new construction methods. The book argues that the use of reduced scale models have played an equally important part in the development of civil and building engineering. However, like the history of engineering design itself, this crucial contribution has not been widely reported or celebrated. The book concludes with reviews of the current use of physical models alongside computer models, for example, in boundary layer wind tunnels, room acoustics, seismic engineering, hydrology, and air flow in buildings.
The unique position of design in the political context of postwar Belgium In the postwar era, design became important as a marker of modernity and progress at world fairs and international exhibitions and in the global markets. The Belgian state took a special interest in this vanguard phenomenon of ‘industrial design’ as a vital political and economic strategic tool in the context of the Cold War and the creation of the European community. This book describes the unique position that design occupied in the political context of postwar Belgium as it analyses the public promotion of design between 1950 and 1986. It traces this process, from the first government-backed manifestations and institutions in the 1950s through the 1960s and 1970s, until design lost its privileged position as a state-backed institution, a process which culminated in the closure of the Brussels Design Centre in 1986, in the midst of the Belgian federalisation process. A key figure in this history is the policymaker Josine des Cressonnières, who played a leading role in the national and international design community and succeeded in connecting very different political worlds through the medium of design.
