ANALYSIS AND DESIGN OF VOIDED SLABBRIDGE

Noura Ismail Ahamed, Ayona Nair S

Abstract: Circular voids are often incorporated into concrete bridge decks to reduce their self-weight without greatly reducing their flexural stiffness. Incorporating voids within the deck slab offers many advantages over a conventional solid concrete slab like lower total cost of construction, reduced material use and increased structural efficiency. However the voids within the structure complicate the analysis of the structure. In this thesis a manual analysis for both longitudinal and transverse direction of voided slab bridge is done as per the industrial standards. For transverse analysis the bridge is idealized using STAAD pro software. The detailing of the complicated structure is also included in order to understand how the reinforcement is placed in the structure.
