Condition Assessment of Main Structural Members of Stream Schooner WAPAMA


Book Description

The historic American ship WAPAMA is the last surviving example of the wooden steam-powered schooners designed for the 19th- and 20th-century Pacific Coast lumber trade and coastal service. Since its launching in 1915, the WAPAMA has had a long and productive life in plying cargo and passengers along the stormy West Coast from Mexico to Alaska. As the sole survivor of the once numerous class, the WAPAMA was declared a National Historic Landmark in 1984. The wood structure of the WAPAMA has significantly deteriorated over the years and currently resides on a barge with internal and external structural supports. Portions of the vessel are unsafe for public access. Assisting in an effort to stabilize and rehabilitate this historic vessel, we conducted a field investigation on the current physical condition of the wooden structural members in January 2006. A variety of nondestructive testing (NDT) methods were employed to locate problem areas and define the severity of deterioration on key structural members such as keelsons, keel, ceiling planking, hull frames, clamps, and main deck beams. This report presents the main findings from this field investigation and demonstrates the use of state-of-the-art NDT technologies in evaluating physical and biological conditions of historic wood structures.




Structural Analysis of Historical Constructions: Anamnesis, Diagnosis, Therapy, Controls


Book Description

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. A special focus has been put on six specific themes: - Innovation and heritage - Preventive conservation - Computational strategies for heritage structures - Sustainable strengthening of masonry with composites - Values and sustainability, and - Subsoil interaction 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.




Structural Investigation of Historic Buildings


Book Description

"Structural Investigation of Historic Buildings: A Case Study Guide to Preservation Technology for Buildings, Bridges, Towers, and Mills provides a practical guide for consulting structural engineers and others on dealing with issues unique to historic structures. Emphasizing structural evaluation and condition assessment based on sound preservation philosophy, but without burdening the reader with tedious calculations, the book discusses the role of the structural engineer in the evaluation and preservation process and discusses such topics as structural safety, analysis, and conservation."--Publisher's website.







Nondestructive Techniques for the Assessment and Preservation of Historic Structures


Book Description

New technologies play an increasingly important role in the analysis, monitoring, restoration, and preservation of historic structures. These technological systems continue to get more advanced and complex, for example: 3D digital construction and documentation programming, 3D imaging data (including laser scanning and photogrammetry), multispectral and thermographic imaging, geophysical data, etc. This book will present the latest nondestructive technologies used in the characterization, preservation, and structural health monitoring of historic buildings. It will include numerous case studies, as well as theoretical explanations about each of the methods and technologies used in each.




Non-Destructive Testing of Structures


Book Description

The Special Issue “Non-Destructive Testing of Structures” has been proposed to present the recent developments in the field of the diagnostics of structural materials and components in civil and mechanical engineering. The papers highlighted in this editorial concern various aspects of non-invasive diagnostics, including such topics as the condition assessments of civil and mechanical structures and the connections of structural elements, the inspection of cultural heritage monuments, the testing of structural materials, structural health monitoring systems, the integration of non-destructive testing methods, advanced signal processing for the non-destructive testing of structures (NDT), damage detection and damage imaging, as well as modeling and numerical analyses for supporting structural health monitoring (SHM) systems.




Conservation of Historic Timber Structures


Book Description

A comprehensive approach to the preservation of historic timber structures. The authors demonstrate that repair methods must be geared towards the specific cultural, architectural and environmental conditions of the area where the timber structure is located.

Chinese Architecture and the Beaux-Arts


Book Description

In the early twentieth century, Chinese traditional architecture and the French-derived methods of the École des Beaux-Arts converged in the United States when Chinese students were given scholarships to train as architects at American universities whose design curricula were dominated by Beaux-Arts methods. Upon their return home in the 1920s and 1930s, these graduates began to practice architecture and create China’s first architectural schools, often transferring a version of what they had learned in the U.S. to Chinese situations. The resulting complex series of design-related transplantations had major implications for China between 1911 and 1949, as it simultaneously underwent cataclysmic social, economic, and political changes. After 1949 and the founding of the People’s Republic, China experienced a radically different wave of influence from the Beaux-Arts through advisors from the Soviet Union who, first under Stalin and later Khrushchev, brought Beaux-Arts ideals in the guise of socialist progress. In the early twenty-first century, China is still feeling the effects of these events. Chinese Architecture and the Beaux-Arts examines the coalescing of the two major architectural systems, placing significant shifts in architectural theory and practice in China within relevant, contemporary, cultural, and educational contexts. Fifteen major scholars from around the world analyze and synthesize these crucial events to shed light on the dramatic architectural and urban changes occurring in China today—many of which have global ramifications. This stimulating and generously illustrated work is divided into three sections, framed by an introduction and a postscript. The first focuses on the convergence of Chinese architecture and the École des Beaux-Arts, outlining the salient aspects of each and suggesting how and why the two "met" in the U.S. The second section centers on the question of how Chinese architects were influenced by the Beaux-Arts and how Chinese architecture was changed as a result. The third takes an even closer look at the Beaux-Arts influence, addressing how innovative practices, new schools of architecture, and buildings whose designs were linked to Beaux-Arts assumptions led to distinctive new paradigms that were rooted in a changing China. By virtue of its scope, scale, and scholarship, this volume promises to become a classic in the fields of Chinese and Western architectural history. Contributors: Tony Atkin, Peter J.
