This paper outlines the application of the multi-layer perceptron artificial neural network (ANN), ordinary kriging (OK), and inverse distance weighting (IDW) models in the estimation of local scour depth around bridge piers. As part of this study, bridge piers were installed with bed sills at the bed of an experimental flume. Experimental tests were conducted under different flow conditions an...

This paper investigates a seismic retrofit technique that allows bridge steel truss piers to uplift and rock on their foundation. Displacement-based passive energy dissipation devices buckling-restrained braces, or BRBs are implemented at the uplifting location to control the rocking response while providing additional energy dissipation. The hysteretic behavior of the controlled rocking system...

A tidal bore may occur in a macro-tidal estuary when the tidal range exceeds 4.5–6 m and the estuary bathymetry amplifies the tidal wave. Its upstream propagation induces a strong mixing of the estuarine waters. The propagation of undular tidal bores was investigated herein to study the effect of bridge piers on the bore propagation and characteristics. Both the tidal bore profile and the turbu...

The use of precast post-tensioned segmental (PPS) piers is growing in the bridge industry, particularly Accelerated Bridge Construction (ABC). To increase their high-seismicity regions, this study focuses on seismic performance PPS under pulse-like near-field earthquakes. Two ensembles 40 ground motions and 44 far-field along with three various heights are used a series incremental dynamic anal...

The issues of scouring around a bridge have become prominent in recent research mainly due to recurrent extreme weather events. Thus, designing with the appropriate protection measures is essential safeguard it against failure, which may take place from high flows resulting Bridges partially or entirely submerged during events such as large floods and are subject pressure-flow scour, condition ...

Mohammad Muzzammil Department of Civil Engineering, AMU, Aligarh, UP 202002, India E-mail: [email protected] An accurate estimation of the maximum possible scour depth at bridge abutments is of paramount importance in decision-making for the safe abutment foundation depth and also for the degree of scour counter-measure to be implemented against excessive scouring. Despite analysis of...
