The third edition of the classic "Reinforced Concrete Bridges" comprehensively addresses the fundamentals of conceptual design, as well as the planning, execution, and maintenance of bridges made of steel and prestressed concrete. These fundamentals are crucial for the aesthetics, load-bearing safety, durability, and cost-effectiveness of a bridge. Simple models achieve a high level of clarity and comprehensibility. Detailed calculations are omitted, as they are usually of secondary importance and have no significant impact on the quality or cost-effectiveness of a bridge. The arrangement of reinforcement and the structural design play a decisive role in the quality and durability of reinforced concrete structures, which is why fundamental solution options are presented. The topics of design, materials, loads, equipment components, etc. are also covered.
