Abstract

Voided slab bridge deck composed of two continuous span is 17.3m Long and 16m width with all over depth of 0.9m. The voided slab is composed of 20cm top and bottom slabs with circular voided areas of 50cm in diameter and center to center of these circles of 75cm. The locations of AASHTO loadings are positioned at certain points of deck slab to give maximum positive and negative shearings. These locations are determined from one dimensional model. The analysis of the bridge deck is carried out by two approaches. The first is AASHTO specifications where one dimensional approach is adopted and the second is three dimensional approach where finite element analysis is considered. The maximum shears obtained by both methods are found to be in good agreement with negligible differences.
