Hi,i have gone through hand on experience in bridge designing right from substructure to superstructure,i did pile foundation,open foundation with all kind of pier and abutment compliance with earthquake and wind loading scour pressure,bearing types fixed and pinned guided using elastomeric and pot ptpf types of material,earthquake arrests,structural steel plate girder,pre stressed concrete girders,both cast in situ and precast concrete deck slab,deck slab designing for temperature,shrinkage and creep stress,i know sophisticated finite element software for generating moving load,grill age type of deck slab for skew and straight bridge type.i can model for tracked and wheel moving load on deck slab,Impact loading calculations,various types of crash barriers
