A seismic improvement works were completed on Market Road Underpass (MRU) in Auckland. The bridge consists of three structures: The Underpass, the Motorway Off-ramp and the Rail Overbridge. In the NZTA’s "Seismic Screening" of all state highway bridges MRU ...

This report presents a methodology for estimating the time rate of scour and the design scour depth for a bridge founded on rock. The report also includes design and construction guidelines for application of the methodology.

This report documents information on materials, specification requirements, design details, application methods, system performance, and costs of waterproofing membranes used on new and existing bridge decks since 1995.

On 22 February 2011 the Mw6.2 Christchurch earthquake occurred with an epicentre less than 10 km from the Christchurch Central Business District (CBD) on an unknown buried fault at the edge of the city. The majority of damage was a result of lateral spreading ...

This report explores recommendations for a predictive equation for equilibrium local scour and a potential equation for predicting scour evolution rates at wide piers and skewed piers. The equations are designed to help provide better estimates of local scour ...

This manual embraces both construction and design of drilled shafts, and addresses the following topics: applications of drilled shafts for transportation structure foundations general requirements for subsurface investigations construction means and methods ...

This report explores guidelines to help estimate the quantity of accumulated, flow event debris, based on the density and type of woody vegetation and river bank condition upstream and analytical procedures to quantify the effects of resulting debris-induced ...

This paper examines the structural behavior of bridge timber piles under eccentric compression loading. Samples of the piles were retrieved from a recently collapsed bridge and experimentally tested under compression and combined compression and flexure. The ...

Over the past decades, an increasing number of integral bridges have been built. This is justified by the various advantages of integral bridges in comparison with standard bridges equipped with expansion joints and bearings. In particular, integral bridges ...

Stonecutters Bridge will have a main span of 1018m to cross the Rambler Channel in Hong Kong, China. The 1596m long cable stayed bridge has a steel main span and concrete back spans. The tapered mono column towers stand on the bridge centre line between the ...
