PTI Anchorage Zone Design
Post-tensioning of concrete requires the introduction of large, concentrated tendon forces into structures. To appreciate the magnitude of these forces, consider a typical bridge tendon with 19-152 mm (0.6 in.) strands. The jacking force for such a tendon may reach close to 4,000 kN (900 kips). This is equivalent to the weight of twelve HS 20-44 trucks Often several long tendons are anchored in…
Investigation of the Effects of Transverse Bending in a Composite Inverted T-…
Abstract: The composite inverted T-slab bridge system provides an accelerated bridge construction alternative for short- to medium-span bridges with spans ranging from 6.1 to 20 m. The system consists of adjacent precast inverted T-slabs with a cast-in-place (CIP) concrete topping. Such a composite bridge system offers a shallow superstructure depth ideal for sites with stringent vertical cle…

Performance of unsealed roads in Ghana
This report gives results of measurements of the condition of unsealed roads made over a period of more than two years. The effects of the maintenance activities of grading and dragging on road surface conditions are assessed. During the study some of the running surfaces deteriorated sufficiently to significantly increase road user costs. Roughness was the aspect of running surface condition w…
