Structural Analysis of Historical Constructions. Anamnesis, diagnosis, therapy, controls contains the papers presented at the 10th International Conference on Structural Analysis of Historical Constructions (SAHC2016, Leuven, Belgium, 13-15 September 2016). The main theme of the book is “Anamnesis, Diagnosis, Therapy, Controls”, which emphasizes the importance of all steps of a restoration process in order to obtain a thorough understanding of the structural behaviour of built cultural heritage. The contributions cover every aspect of the structural analysis of historical constructions, such as material characterization, structural modelling, static and dynamic monitoring, non-destructive techniques for on-site investigation, seismic behaviour, rehabilitation, traditional and innovative repair techniques, and case studies. The knowledge, insights and ideas in Structural Analysis of Historical Constructions. Anamnesis, diagnosis, therapy, controls make this book of abstracts and the corresponding, digital full-colour conference proceedings containing the full papers must-have literature for researchers and practitioners involved in the structural analysis of historical constructions.

This book gathers the latest advances, innovations and applications in the field of historic mortars and masonry structures conservation and restoration, as presented by international researchers and professionals at the 6th Historic Mortars Conference (HMC), held in Ljubljana, Slovenia, on September 21–23, 2022. It covers topics such as characterization of historic mortars and masonry structures—sampling and test methods; historic production, processing and application of mortars, renders and grouts; assessment of historic renders and plasters; conservation and preventing conservation case studies; repair mortars and grouts—requirements and design, compatibility issues, durability and effectiveness and adequacy of testing procedures. Special attention is given to historic mortars where one of the binders or the only binder is Portland cement and to the structures in which these materials are used. The contributions, which were selected through a rigorous international peer-review process, share new knowledge and exciting ideas that will help protect heritage buildings more efficiently and foster new multidisciplinary collaborations in this area.

Der Holzbau ist seit einigen Jahren einer der innovativsten Bereiche des Bauwesens. Die Geschwindigkeit, mit der neue Produkte in die Praxis eingeführt werden, ist im Vergleich zu anderen Baustoffen fast atemberaubend. So gewinnt der Holzbau im Gewerbe- und Hallenbau, aber auch im mehrgeschossigen Wohn- und Bürobau kontinuierlich an Marktanteil. Dieses Buch vermittelt wesentliche Kenntnisse und Fertigkeiten, die für den Entwurf, die Bemessung und die Konstruktion von Holzkonstruktionen für typische Bauwerke erforderlich sind. Besonderes Augenmerk wird auf die spezifischen Eigenschaften von Holz und Holzwerkstoffen im Vergleich zu anderen Baustoffen gelegt. Dies betrifft die zahlreichen Vorteile, wie z. B. das vergleichsweise geringe Gewicht, die gute Verarbeitbarkeit des Hochleistungswerkstoffs und die große Vielfalt an Montagetechniken, aber auch die Herausforderungen, die sich aus der Materialanisotropie und aus der Anfälligkeit für natürliche Schädlinge ergeben. In jedem Kapitel werden zunächst die wesentlichen Phänomene erläutert und erst danach in Zusammenhang mit Regelwerken gebracht. Damit soll das Grundverständnis für die Zusammenhänge und Abhängigkeiten im Holzbau unterstützt werden, das die wesentliche Grundlage für kreative Ingenieurarbeit ist.

This book presents the most recent advances on testing and experimentation in civil engineering, especially in the branches of materials, structures, and buildings, complementing the authors’ publication Advances on Testing and Experimentation in Civil Engineering - Geotechnics, Transportation, Hydraulics and Natural Resources. It includes advances in physical modelling, monitoring techniques, data acquisition and analysis, and provides an invaluable contribution to the installation of new civil engineering experimental facilities. The first part of the book covers the latest advances in the testing and experimentation of key domains of materials, such as bio-cementation and self-healing, durability, and recycled materials, as well as the new environmental requirements related to the presence of hazardous substances in construction materials. Furthermore, laboratory and in situ tests, together with equipment needed to estimate the behaviour and durability of construction materials are presented, updating the most important technological advances. The second part of the book highlights the relevance of testing and monitoring in structures, including in situ tests related to static load tests, dynamic tests, and long-term monitoring strategies, as well as laboratory tests of adhesive joints. Experimental tests on shake tables and blast-resistant structures are also described. Recent applications of drone technologies for the inspection and monitoring of civil structures are another important theme developed. Finally, in its third part, the book presents new developments in the characterisation of building testing, with the support of modelling, to assess building pathology and new requirements, acoustic comfort, fire safety, visual comfort, and energy consumption.

Eco-Efficient Rendering Mortars: Use of Recycled Materials focuses on the use of waste materials into cement-based renders, discussing the origins, treatment processes and properties of relevant wastes. The book dispels mistrust through demonstrating the technical feasibility and environmental benefits of eco-efficient rendering mortars. It considers the characteristics of different waste products, such as aggregates, fillers, binders and additions. The functional requirements of renders are also discussed alongside their impact. Finally, the title considers the lifecycle and durability of modified mortars. This book offers robust support and clear guidance on the use of wastes as a substitute for natural aggregates and binders. Presents evidence supporting the use of wastes as a substitute for natural aggregates and binders Characterizes wastes and considers how to best incorporate different kinds of waste into renders Gives details on the technical efficiency and environmental impact of different waste materials on mortars Analyzes the impact of wastes on render performance in terms of fresh state, mechanical, water and durability Considers the lifecycle assessment and durability of modified mortars

The thermal protection requirements for cold weather masonry, as established in current industry specifications, were evaluated. Experiments were conducted to define the most relevant factors in the process of freezing of newly placed mortar. The effect of unit absorption on the moisture content of mortar during the first hours after assembly was assessed. Correlations of moisture content with time were developed for mortar in contact with masonry units. Frost immunity thresholds in terms of mortar moisture content and in terms of maturity were determined. The test results provided the basis for new proposed guidance on when fresh mortar can be safely exposed to freezing temperatures. Test methods for evaluation of the freeze thaw resistance of masonry units were evaluated. A new test was proposed and adopted by ASTM as a new standard test for the freeze thaw testing of masonry units. In addition, several chemicals were evaluated for their potential as antifreeze admixtures for masonry mortar. Antifreeze admixtures were first developed for use in concrete, but the practicality of using antifreeze admixtures in masonry mortars was demonstrated in a field application in Michigan during the winter.
