Structural Studies, Repairs and Maintenance of Historical Buildings: 6th(Advances in Architecture)

Public appreciation of the benefits and values of our architectural heritage has advanced considerably over the past decades. The part played by old buildings in the historical identity of a region, town or nation is increasingly recognised and appreciated, and their effective preservation requires looking beyond borders and continents to benefit from the experience gained by others. The International Conferences on Structural Studies, Repairs and Maintenance of Historical Buildings (STREMAH) provide an ideal forum for architects, curators, engineers, art historians, surveyors and archaeologists from around the world to exchange opinions and experiences, present the most up-to-date scientific and practical findings, and discuss problems and solutions. This volume features a large number of contributions from the sixth meeting in the series, held in June 1999. Containing state-of-the-art research and recent case studies, the book is divided into the following sections: Experimental Techniques; Monitoring and Testing; Mathematical Simulation and Computer Modelling; Deterioration, Protection and Evaluation of Materials; Seismic Behaviour and Repairs; Case Studies; Historical, Social and Architectural Aspects; Long Term Effects due to Environmental Causes; Techniques and Repairs; Maintenance and Restoration of Historical Buildings; Prevention of Structural Damage; Stabilisation, Underpinning and Reinforcement; The Revival of Dresden.
