Most bridges in the highways of the Netherlands are designed to last 80 years. In those 80 years only minor damage should be repaired. To determine the repair strategy of these minor damages the so-called Lifetime Extending Maintenance model can be used. This model is a condition model, which has been used for many materials like paint on steel [1]. In this paper we will show an application of ...

Acoustic emission (AE) testing was deployed on details of two large steel Interstate Highway bridges: one cantilever through-truss and one trapezoidal box girder bridge. Quantitative measurements of activity levels at known and suspected crack locations were made by monitoring AE under normal service loads (e.g., live traffic and wind). AE indications were used to direct application of radiogra...

December 2000 OVERVIEW Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands or bars, typically referred to as tendons. Post-tensioning applications include office and apartment buildings, parking structures, slabs-on-ground, bridges, sports stadiums, rock and soil anchors, and water-tanks. In many cases, posttensioning allows co...

Abstract Steel-concrete composite bridges are a popular solution due to the structural benefits of both steel and concrete. The typical system concrete slab I-girders for small medium-span often displays most economical results. However, other solutions emerge as innovative alternatives bridge construction, such beams with dowels pre-cambered beams. This paper aims develop comparative study the...
