Failures in concrete structures: case studies in reinforced and prestressed concrete

Some lessons are only learned from mistakes but, it's much cheaper to learn from someone else's mistakes than to have to do so from your own. Drawing on over fifty years of working with concrete structures, Robin Whittle examines theproblems which he has seen occur and shows how they could have been avoided.The first and largest part of the book tells the stories of a number of caseswhere things have gone wrong with concrete structures. Each case is analyzed to identify its cause and how it might have been prevented. It then looks at how failures in structural modelling can lead to big problems if they are not identified before construction is undertaken. Beyond this it examines how contract arrangements can encourage or prevent problems in the designing and building processes. It concludes with an examination of the role research and development in preventing failures. By identifying the differences between shoddy economizations and genuine efficiency savings, this book offers savings in the short term which won't be at the expense of a structure's long-term performance. Invaluable reading if you're designing or building concrete structures and want to avoid problems which could be expensive or embarrassing further down the line. INDICE: Part 1: Case Studies 1.
