Learning outcomes of the course unit

Limit states of metal bridges. Material of metal bridges. Load of bridge structures. Overview of basic structural systems of web-plate beam and truss girder metal bridges: railway bridges - bridge deck with transverse beams and stringers, rail-bed bridge deck; road bridges - bridge deck with transverse beams and stringers, orthotropic bridge deck, composite steel-concrete bridges. Static design of bridge deck members: stringers and tranverse beams; rail-bed bridge deck - longitudinal and trensverse stiffnesses. Static design of bridge main girders: web-plate and truss bridges.

Prerequisites

Structural mechanics: basic principles of static solution - simple supported and continuous girders, truss structures. Metal structures - design of members and connections of steel structures. Concrete structures - basic principles of design of concrete structures.

Co-requisites

Extension of the knowledge in the field of structural mechanics - live load by traffic effects, influence lines. Extension of the knowledge in the field of elasticity and strength - global analysis of load-carrying systems of metal bridges (elastic and plastic analysis).
