A substructure of bridges is very important structural element for safety and supporting not only vertical loads as dead load and live load but lateral loads as break load, wind load, seismic load, hydrostatic pressure and dynamic water pressure, lateral earth pressure, impulsive load, temperature change and load effect of temperature change, creep and shrinkage. Most of domestic bridges are reinforced concrete piers and have an effect on economy of bridge. Recently, understanding importance of substructure, we are getting more interested in new substructure system.
