Elastic investigation of piers numbers effects in transverse direction on the stiffness of continuous and simply supported bridges

Piers were important structural members between superstructure and foundation of bridge which were designed to transfer and resist the vertical loads and horizontal loads (dead load of structure, traffic loads, water pressure, ice, and wind) to the foundation. The objective of this study was to eval...
