This paper presents the case study of highly skewed three-cell reinforced cement concrete bridge, in which distresses in the form of diagonal cracks connecting the acute-angled corners in the soffit of the deck slabs were seen immediately after opening the bridge for the traffic. The aim of this study was to investigate the reasons for the distress observed in the bridge and to suggest suitable strengthening measures. To identify the reason of distress in the bridge, structural design of this bridge was reviewed and the non-destructive tests as well as core tests on the concrete were undertaken besides detailed visual inspection. Based upon the result of this study, it was concluded that insufficient longitudinal reinforcement in the direction of principal bending and the lower grade of concrete than designed, may be attributed as the one of the reasons for the development of diagonal cracks connecting the acute-angled corners in the soffit of the deck slab. Based on the present strength of the concrete and provided steel reinforcement, resisting bending moment capacity of the bridge was calculated. Repair and rehabilitation scheme was recommended for the shortfall capacity. This paper highlights the importance of understanding the structural behaviour of the skew bridges amongst the bridge designers especially when they are dealing with highly skewed bridges (skew angle > 30°). This will enable them to be cautious whilst designing, detailing and constructing skewed bridges to avoid the kind of distresses observed in this case study.]]> Tue, 09 Jan 2024 16:16:31 GMT https://trid.trb.org/View/2312873
