Opis

This is a treatment of structural modelling for applications in design, research, education and product development. Providing numerous case studies throughout, the book emphasizes modelling the behaviour of reinforced and prestressed concrete and masonry structures. This book aims to serve students in model analysis and experimental methods, professionals manufacturing and testing structural models, as well as professionals testing large or full-scale structures since the instrumentation techniques and overall approaches for testing large structures are very similar to those used in small scale modelling work.
