Introductory technical guidance for civil and structural engineers interest in design of box girder structures for bridges and highways. Here is what is discussed: 1. INTRODUCTION 2. BENDING MOMENTS CAUSED BY UNIT EFFECTS 3. DEAD LOAD—DC (SELF WEIGHT AND BARRIER RAILING) 4. DEAD LOAD—DW (FUTURE WEARING SURFACE) 5. LIVE LOAD—LL (LANE AND TRUCK COMPONENTS) 6. POST-TENSIONING SECONDARY MOMENTS—UNIT PRESTRESSING FORCE. 7. THERMAL GRADIENT (TG)—20°F LINEAR. 8. MOMENTS RESULTING FROM TEMPERATURE RISE AND FALL 9. MOMENTS RESULTING FROM CONCRETE SHRINKAGE 10. MOMENTS RESULTING FROM CONCRETE CREEP 11. BENDING MOMENTS SUMMARIES 12. POST-TENSIONING FORCE COMPARISON (AFTER ALL LOSSES, WITH THERMAL EFFECTS).
Introductory technical guidance for civil and structural engineers interested in design of prestressed highway box girders. Here is what is discussed: 1. DESIGN 2. LONGITUDINAL DESIGN 3. MATERIALS 4. PRELIMINARY DESIGN 5. PRESTRESSING 6. PRESTRESSING LOSSES 7. SUBSTRUCTURE CONSIDERATIONS.
&Quot;This book is an essential purchase for all those involved in bridge construction and innovative building techniques, such as bridge owners, design offices, bridge consultants, and construction equipment suppliers."--BOOK JACKET.
Introductory technical guidance for civil and structural engineers and construction managers interested post-tensioned box girders design for highway and bridge structures. Here is what is discussed: 1. INTRODUCTION 2. TYPICAL SUPERSTRUCTURE CROSS SECTIONS 3. LONGITUDINAL POST-TENSIONING LAYOUTS 4. LOSS OF PRESTRESSING FORCE 5. POST-TENSIONING SYSTEM HARDWARE 6. OVERVIEW OF CONSTRUCTION.
The traveling public has no patience for prolonged, high cost construction projects. This puts highway construction contractors under intense pressure to minimize traffic disruptions and construction cost. Actively promoted by the Federal Highway Administration, there are hundreds of accelerated bridge construction (ABC) construction programs in the United States, Europe and Japan. Accelerated Bridge Construction: Best Practices and Techniques provides a wide range of construction techniques, processes and technologies designed to maximize bridge construction or reconstruction operations while minimizing project delays and community disruption. - Describes design methods for accelerated bridge substructure construction; reducing foundation construction time and methods by using pile bents - Explains applications to steel bridges, temporary bridges in place of detours using quick erection and demolition - Covers design-build systems' boon to ABC; development of software; use of fiber reinforced polymer (FRP) - Includes applications to glulam and sawn lumber bridges, precast concrete bridges, precast joints details; use of lightweight aggregate concrete, aluminum and high-performance steel

First Published in 1999: The Bridge Engineering Handbook is a unique, comprehensive, and state-of-the-art reference work and resource book covering the major areas of bridge engineering with the theme "bridge to the 21st century."
