Crack Evolution Of Masonry Wall Due To Differential Ground Settlement

Some researchers have studied damage of masonry buildings due to differential displacements, by assuming that masonry is a homogeneous isotropic material. To determine masonry crack evolution, further study needs to be done with more precise modeling of brick and mortar joints. In this study, by using the finite element code LS-DYNA, the masonry walls are modeled by using 8-node solid elements for the brick and mortar joints. The main objectives of the research are to study the effect of differential ground settlement on RC buildings with masonry infill walls with and without openings and to examine the associated evolution of crack patterns.

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.

All the traces of historic heritage are a fundamental part of our environment and reward us in the form of cultural enrichment, with the ability to have a positive effect both on our lifestyle and economy. Therefore, the preservation of ancient monuments, historic towns and sites has increasingly drawn the attention of public opinion, governmental agencies as well as consultants and contractors. This interest must be however carefully controlled and directed, since the conservation of monuments and historic sites is one of the most challenging problems of our age. Careless attempts at preservation can be detrimental not only to their iconic value (formal integrity), but even to their structural characteristics and the materials they are built with (material integrity). Geotechnical Engineering for the Preservation of Monuments and Historic Sites collects one opening address, four special lectures and 82 contributions from all over the world, giving a unique sample of the geotechnical problems to be tackled, the solutions currently being proposed, and the strategies being carried out to preserve the overall integrity of monuments and historic sites. It is clearly apparent that differences exist around the world not only in terms of the characteristics of the monuments or sites to be preserved, but also in the approaches adopted to achieve this aim. Hence, no unique solution is available to the geotechnical engineer dealing with the delicate structures and sites that represent our cultural heritage, and knowledge of previous experiences may be a unique guide in any technical decision-making process.

A valuable source of reference on the current practices of analysis, design and construction of tunnels and underground structures in soft ground. This collection of reviewed papers covers a wide range of tunnelling practice, from deep excavations in Singapore to the construction of a new metro line in Barcelona. The international scope of the contributors makes this a truly comprehensive collection of work on the geotechnical aspects of soft ground excavation.

A comprehensive resource that builds a bridge between engineering disciplines and the building sciences and trades, Forensic Engineering: Damage Assessments for Residential and Commercial Structures provides an extensive look into the world of forensic engineering. With a focus on investigations associated with insurance industry claims, the book describes methodologies for performing insurance-related investigations including the causation and origin of damage to residential and commercial structures and/or unhealthy interior environments and adverse effects on the occupants of these structures. Edited by an industry expert with more than 30 years of experience, and authors with more than 100 years of experience in the field, the book takes the technical aspects of engineering and scientific principles and applies them to real-world issues in a non-technical manner. It provides readers with the experiences, investigation methodologies, and investigation protocols used in, and derived from completing thousands of forensic engineering investigations. It begins with providing a baseline methodology for completing forensic investigations and closes with advice on testifying as an expert witness. Much of what must be known in this field is not learned in school, but is based upon experience since recognizing the cause of a building system failure requires a blending of skills from the white collar and blue collar worlds. Such knowledge can be vital since failures (e.g., water entry) often result from construction activities completed out of sequence.. This book details proven methodologies based on over 7,000 field investigations, methodologies which can be followed by both professionals and laymen alike.

This book deals with all the tasks related to brick and stone masonry structures, from the initial identification of defects and their diagnosis to their treatment and monitoring of its cost-effectiveness. It is written in the context of bridges and their associated retaining walls in the U.K.

Structural analysis of architectural heritage is a new and growing branch of engineering. Knowledge of the history of architecture, material characteristics, instruments and techniques for investigations, diagnosis and restoration are all vital aspects for the correct understanding of structural behaviour and the ability to make correct decisions for repair and strengthening techniques. Designed for use by all professionals involved or interested in the preservation of monuments, the purpose of this book is to contribute to the development of new approaches in the area. Many of the examples examined, including the Colosseum, the Tower of Pisa, the Pyramid of Chephren, the Tilla Kari Mosque in Samarkand, the temples of Angkor and Konarak, the Santa Maria Vieja Cathedral, the domes of St Peter, Hagia Sophia, the Pantheon, St Ignatio de Loyola and St Charles, are the result of projects and studies carried out during Giorgio Croci's distinguished career. The book features numerous black and white photographs and illustrations by the author.
