Evaluating Support Conditions for Precast Concrete Inlay

A hybrid solution proposal for precast tunnel segments

A considerable increase in tunnel constructions can be accounted to the introduction of mechanized tunneling and the constant evolution of boring machines. 3 Furthermore, in soft ground, weak rocks or, generally, in complex ground conditions, mechanized tunneling oftentimes is the method of choice. 4 In this case, the tunnel lining is usually

Contemporary Appeal for University Gateway Building - Precast

For a cast-in-place concrete-framed structure, you need to get to six or eight stories to really get the economy,” Tredo points out. And since Zilber Hall’s outer precast panels are gravity supported, they don’t require significant additional support. Established history of precast solutions

Seismic Performance Evaluation of Precast Concrete Beam-to

The sections of precast concrete beam in PCB-SLCC specimens are all based on 250 mm × 400 mm × 2000 mm, and the distribution of longitudinal and transverse reinforcements is the same as the precast concrete beam described in Section 4.1. The very short shear link in PCB-SLCC models is based on a section of H200 × 150 × 6 × 8, and the

Waterfront Structures | Geotechnical Engineering | MRCE

Marine structure inspections are often challenged by restricted access, tidal conditions, and currents. MRCE engineers specializing in the design and rehabilitation of waterfront structures are adept at defining the structural system, evaluation of damage to structural components (marine borers, dry rot, spalling, and steel and concrete quality) to determine the remaining structural life or

Debonding Detection in the Grouted Joints of Precast

A grout layer between precast concrete components in an assembly structure is required to bear high axial loads and withstand significant shear forces during earthquakes. Since the grout layer usually exists in a narrow space, examining the quality of the layer, particularly detecting debonding at the interface, is a difficult task. However, a debonding defect at the interface is likely to
