Steel Bridges
Steel bridges have a long and proud history. The development of the long‐span truss bridge was in response to the need of railroads to cross waterways and ravines without interruption. This chapter describes the steel bridge material properties. The typical raw materials for making steel are iron ore, coke, limestone, and chemical additives. Mini mills are smaller steel mills that use recycled steel in electric‐arc furnaces as the primary heat source. As sustainable building material, steel is among the best. The liquid steel from the ladle is placed in ingot molds or a continuous casting machine. Stresses that exist in a component without any applied external forces are called residual stresses. Improved properties of steel can be obtained by various heat treatments. The high‐strength heat‐treated alloy steels are weldable but are available only in structural steel plates for bridges.
