The mechanisms by which buildings and infrastructures degrade are complex, as are the procedures and methods for inspection and for rehabilitation. This book examines the various problems caused by non-uniform deformation changes, poor durability, and natural and human disasters such as earthquakes and fire. It explores the causes and mechanisms of deterioration and introduces general procedures and commonly used techniques for inspection and evaluation of existing infrastructures. The book examines conventional renovation techniques, compatibility between repair materials and degraded materials, and fibrous composite materials. It also discusses fibrous composite strengthening techniques for beam, wall, column and slabs along with codes of practice for retrofitting with fibrous composites.
