This book focuses on the durability problems of existing prestressed concrete (PC) structures caused by strand corrosion, clarifies the mechanical behavior of corroded prestressing strands, corrosion-induced cracking, bond degradation, prestress loss and structural performance deterioration, and proposes the corresponding prediction models.

Introduction.- Effect of corrosion on mechanical behaviors of prestressing strands.- Corrosion-induced cracking of prestressed concrete.- Effect of corrosion-induced crack on the bond between strand and concrete.- Bond-slip model of corroded strand considering rotation effect.- Prestress loss and transfer length prediction in pretensioned concrete structures with corrosive cracking.- Secondary anchorage and prestress loss of fractured strand in PT beams.- Flexural behaviors of corroded posttensioned concrete beams.- Bearing capacity prediction of corroded PC beams incorporating grouting defects and bond degradation.

This is an open access book. This book focuses on the durability problems of existing prestressed concrete (PC) structures caused by strand corrosion, clarifies the mechanical behavior of corroded prestressing strands, corrosion-induced cracking, bond degradation, prestress loss and structural performance deterioration of PC structures, and proposes the corresponding prediction models. We hope that this text may be useful for those who work in the field of civil and construction engineering, as well as for those involved in the area of maintenance and management of prestressed concrete structures. Its aim is to provide the knowledge, tools, and methods to understand the deterioration phenomena of prestressed concrete structures.It is suitable for teachers and students majoring in civil engineering in universities, and researchers in the field of civil engineering. It is also suitable for practitioners of design institutes, construction units, supervising units and trafficmanagement departments. This book is also applicable to anyone else who wants to understand the corrosion of strand. Enthusiasts of civil engineering are also a potential audience. At the same time, this book can also stimulate the interest of young scholars in interdisciplinary research.

Summarizes the research work on durability of prestressed concrete structures in recent ten years Provides an abundant and comprehensive knowledge of prestressed concrete structures Shares experimental studies and case studies on corrosion-induced structural deterioration This book is open access, which means that you have free and unlimited access
