Was wissen Bauingenieure heute über die Herkunft der Baustatik? Wann und welcherart setzte das statische Rechnen im Entwurfsprozess ein? Wir ahnen wohl, dass die Entwicklung von Berechnungsmethoden und -verfahren im engen Zusammenhang mit der Entdeckung neuer Baumaterialien und der Hervorbringung und Entfaltung von Tragformen stehen. Das vorliegende Buch zeichnet die Entstehung von Statik und Festigkeitslehre als die Entwicklung vom geometrischen Denken der Renaissance über die klassische Mechanik bis hin zur modernen Strukturmechanik nach. Eine Einführung eröffnet mit kurzen Einblicken in zwölf verbreitete Berechnungsverfahren den Zugang zu über 500 Jahren Geschichte der Baustatik aus der Berechnungspraxis der Gegenwart. Beginnend mit den Festigkeitsbetrachtungen von Leonardo und Galilei wird der Herausbildung einzelner baustatischer Verfahren und ihrer Formierung zur Baustatik nachgegangen. Dabei gelingt es dem Autor auch, die Unterschiedlichkeit der Akteure hinsichtlich ihrer technisch-wissenschaftlichen Profile und ihrer Persönlichkeiten plastisch zu schildern und das Verständnis für den jeweiligen gesellschaftshistorischen Kontext zu erzeugen. 243 Kurzporträts maßgeblicher Protagonisten der Mechanik, Mathematik, des Maschinen- und Flugzeugbaus und der Baustatik sowie eine umfangreiche Bibliografie machen das Werk zusätzlich zu einer unschätzbaren Fundgrube. Mit diesem Buch liegt der Fachwelt das einzige geschlossene Werk über die Geschichte der Baustatik vor. Es lädt den Leser zur Entdeckung der Wurzeln der modernen Rechenmethoden ein. Die 1. Auflage von 2002 war schnell vergriffen. Für die 2. Auflage ergänzte der Autor sein Werk um wichtige Reisen in die Geschichte der Disziplinbildung: Erddrucktheorie, Traglastverfahren, historische Lehrbuchanalyse, Stahlbrückenbau, Schalentheorie, Computerstatik, Finite-Elemente-Methode, Computergestützte Graphostatik, Historische Technikwissenschaft.

The subject of earth pressure is one of the oldest and most extensive chapters in soil mechanics and foundation engineering and is one of the pillars of structural engineering. First the development of earth pressure theory is comprehensively described. The descriptions range from the first approaches to the determination of earth pressure through continuum mechanical earth pressure models to the integration of earth pressure research into the disciplinary structure of geotechnics. The main part of the book comprises a selection of current calculation basics. The aim is to provide a collection of working instructions for foundation and structural engineers in construction companies, consultants and in building supervision as well as students. In order to further theoretical understanding, the essential basics of the determination of earth pressure are first presented. Then the most important processes for active and passive earth pressure and at-rest earth pressure for practical application are dealt with, with spatial effects also being taken into account. The book sets out to provide brief information about rarely encountered questions with references to further literature. In recent years, the dependency of earth pressure on displacement has been paid ever more attention. This applies not just to the passive but also to the active case. Questions are repeatedly passed to the DIN committee "calculation processes". A selection of these is dealt with in the commentary to DIN 4085, which came out in September 2018. The history of earth pressure theory is supplemented by 40 selected short biographies of scientists and practical engineers, who have taken up the subject and further developed it over the years. The book also has two appendices with terms, formula symbols and indices as well as earth pressure tables.

The author tells the fascinating history of falsework and scaffolding for buildings, bridges, and auxiliary transport structures through centuries. He discusses building methods and construction types and their distribution, and he shows how building technologies were formatted.

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.
