Comprising papers presented at the 15th International Conference on Studies, Repairs and Maintenance of Heritage Architecture this volume brings together global contributions from scientists, architects, engineers and restoration experts dealing with different aspects of heritage buildings, including the preservation of architectural heritage. The importance of retaining the built cultural heritage cannot be overemphasised. Rapid development and the inappropriate conservation techniques are threatening many built cultural heritage unique sites in different parts of the world. This current volume covers a wide range of topics related to the historical aspects and the reuse of heritage buildings, as well as technical issues on the structural integrity of different types of buildings, such as those constructed with materials as varied as iron and steel, concrete, masonry, wood or earth. Material characterisation techniques are also addressed, including non-destructive tests via computer simulation. Modern computer simulation can provide accurate results demonstrating the stress state of the building and possible failure mechanisms affecting its stability. The included papers focus on such topics as: Heritage architecture and historical aspects; Learning from the past; Surveying and monitoring; Modern (19th/20th century) heritage; Ports and coastal heritage; Heritage masonry structures; Wooden structures; New technologies and materials; Corrosion and material decay; Seismic vulnerability and retrofit; Re-use of heritage buildings; Heritage and tourism; Conservation policies; Guidelines, codes and regulations for heritage; Heritage management; Defence, Industrial and Transportation heritage; Social, cultural and economic aspects; Adaptability and accessibility; Monitoring and damage detection; Vernacular architecture.
