Reflecting the authors' extensive experience, and describing the results of projects they have worked on, this book deals with applications of advanced computational mechanics techniques in structural analysis, strength rehabilitation and aseismic design of monuments, historical buildings and related structures. The results are given with clear explanations so that civil and structural engineers, architects and archaeologists, and students of these disciplines can understand how to evaluate the structural worthiness of heritage buildings without the use of difficult mathematics.
Advances in Engineering Materials, Structures and Systems: Innovations, Mechanics and Applications comprises 411 papers that were presented at SEMC 2019, the Seventh International Conference on Structural Engineering, Mechanics and Computation, held in Cape Town, South Africa, from 2 to 4 September 2019. The subject matter reflects the broad scope of SEMC conferences, and covers a wide variety of engineering materials (both traditional and innovative) and many types of structures. The many topics featured in these Proceedings can be classified into six broad categories that deal with: (i) the mechanics of materials and fluids (elasticity, plasticity, flow through porous media, fluid dynamics, fracture, fatigue, damage, delamination, corrosion, bond, creep, shrinkage, etc); (ii) the mechanics of structures and systems (structural dynamics, vibration, seismic response, soil-structure interaction, fluid-structure interaction, response to blast and impact, response to fire, structural stability, buckling, collapse behaviour); (iii) the numerical modelling and experimental testing of materials and structures (numerical methods, simulation techniques, multi-scale modelling, computational modelling, laboratory testing, field testing, experimental measurements); (iv) innovations and special structures (nanostructures, adaptive structures, smart structures, composite structures, bio-inspired structures, shell structures, membranes, space structures, lightweight structures, long-span structures, tall buildings, wind turbines, etc); (v) design in traditional engineering materials (steel, concrete, steel-concrete composite, aluminium, masonry, timber, glass); (vi) the process of structural engineering (conceptualisation, planning, analysis, design, optimization, construction, assembly, manufacture, testing, maintenance, monitoring, assessment, repair, strengthening, retrofitting, decommissioning). The SEMC 2019 Proceedings will be of interest to civil, structural, mechanical, marine and aerospace engineers. Researchers, developers, practitioners and academics in these disciplines will find them useful. Two versions of the papers are available. Short versions, intended to be concise but self-contained summaries of the full papers, are in this printed book. The full versions of the papers are in the e-book.

On March 17 1989, the Civic Tower of Pavia collapsed without apparently any warning sign, killing four people. After an experimental and analytical investigation lasted nine months, the collapse cause was found in a progressive damage dating back many years and due mainly to the heavy dead load put on top of the existing medieval tower when realising a massive bell-tower in granite. Other case histories have been collected as the collapse of the St. Marco bell-tower in Venice in 1902, of the Sancta Maria Magdalena bell-tower in 1992 in Dusseldorf, the damages of the bell-tower of the Monza Cathedral and of the Torrazzo in Cremona. Later on, in 1996 the collapse of the Noto Cathedral showed that similar progressive damages can take place in pillars of churches and cathedrals. The experimental research aimed to show the reliability of this interpretation went on and it is still continuing since 1989 and it is described in the book. After a careful interpretation of the experimental results, also based on experiences from rock mechanics and concrete, the modelling of the phenomenon for massive structures as creep behaviour of masonry was implemented. The book has the scope of helping architects and engineers to deal with the continuous damage of heavy structures and, to understand the signs of the phenomenon while proposing some modelling, but also to give guidelines for the on site investigation, monitoring and repairing of the damaged structures.
According to the ancient Greeks, nature was composed of four elements: air, fire, water and earth. Engineers are continuously faced with the challenges imposed by those elements, when designing bridges and tall buildings to withstand high winds; constructing fire resistant structures, controlling flood and wave forces; minimizing earthquake damage; prevention and control of landslides and a whole range of other natural forces. Natural disasters occurring in the last few years have highlighted the need to achieve more effective and safer designs against extreme natural forces. At the same time, structural projects have become more challenging. Featuring contributions from the First International Conference on Engineering Nature, this book addresses the problems associated in this field and aims to provide solutions on how to resist extreme natural forces. Topics include: Hurricane, Tornadoes and High Winds; Aerodynamic Forces; Fire Induced Forces; Wave Forces and Tsunamis; Landslides and Avalanches; Earthquakes; Volcanic Activities; Bridges and Tall Buildings; Large Roofs and Communication Structures; Underground Structures; Dams and Embankments; Offshore Structures; Industrial Constructions; Coastal and Maritime Structures; Risk Evaluation; Surveying and Monitoring; Risk Prevention; Remediation and Retrofitting and Safety Based Design.

This book is a practitioner-friendly approach to dynamics on structural design, oriented to facilitate understanding of complicated issues without their elaborate mathematical formulations.While the chapters follow logically from one another, each one deals independently with a subject in structural dynamics; this approach allows the engineer to go directly to the topic of his or her interest at a given moment.Throughout each chapter the reader will find the text set in two different forms, for different levels of the topic in consideration, which will enable him to postpone for a second reading deeper explanations.Conceived as practical support for engineers whenever they want to review a subject related to dynamics in the practice of structural design, this book can be of great help for students of engineering.
This book provides an overview to those most important modern and traditional methods of masonry analysis that are able to capture the discrete internal built-up of masonry structures. Such methods are available in a wide variety today – from computational packages based on classical graphical statics techniques through discrete element methods or the most sophisticated no-tension semi-continuum models – , and this book reviews their theoretical foundations, as well as their advantages and preferable fields of application, also calling the attention on their limitations so that the reader could build up a critical view of the choices they have when attacking a masonry mechanics problem. The book gives a basis for the readers to become able to develop their own methods, inspired either by classical graphical statics, or by any modern technique they find promising.

This book presents a unique guide to heritage preservation problems and the corresponding state-of-the-art digital techniques to achieve their plausible solutions. It covers various methods, ranging from data acquisition and digital imaging to computational methods for reconstructing the original (pre-damaged) appearance of heritage artefacts.The case studies presented here are mostly drawn from India’s tangible and non-tangible heritage, which is very rich and multi-dimensional. The contributing authors have been working in their respective fields for years and present their methods so lucidly that they can be easily reproduced and implemented by general practitioners of heritage curation. The preservation methods, reconstruction methods, and corresponding results are all illustrated with a wealth of colour figures and images.The book consists of sixteen chapters that are divided into five broad sections, namely (i) Digital System for Heritage Preservation, (ii) Signal and Image Processing, (iii) Audio and Video Processing, (iv) Image and Video Database, and (v) Architectural Modelling and Visualization. The first section presents various state-of-the-art tools and technologies for data acquisition including an interactive graphical user interface (GUI) annotation tool and a specialized imaging system for generating the realistic visual forms of the artefacts. Numerous useful methods and algorithms for processing vocal, visual and tactile signals related to heritage preservation are presented in the second and third sections. In turn, the fourth section provides two important image and video databases, catering to members of the computer vision community with an interest in the domain of digital heritage. Finally, examples of reconstructing ruined monuments on the basis of historic documents are presented in the fifth section. In essence, this book offers a pragmatic appraisal of the uses of digital technology in the various aspects of preservation of tangible and intangible heritages.
