THE SHEAR BEHAVIOUR OF THE REINFORCED CONCRETE FOUR-PILE CAPS
… capacity of 2-way spanning reinforced concrete pile caps from bending theory-based empirical design formulae. This causes designers difficulty to predict an accurate shear capacity of the pile cap. The inherently empirical character of the formulae is due to the fact that the formulae have been …

Investigation of the Resistance of Pile Caps to Lateral Loading
… These foundations consist of groups of piles coupled together by concrete pile caps. These pile caps, which are often massive and deeply buried, would be expected to provide significant resistance to lateral loads. However, practical procedures for computing the resistance of pile caps …

Seismic Performance of Prestressed Concrete Piles In Cip Reinforced Concrete Pile Caps
<p>The behavior of precast prestressed piles in cast-in-place (CIP) reinforced concrete bent caps subjected to seismic loading is not well understood. Current standard SCDOT connection details require the plain embedment of the pile into the bent cap one pile diameter with a construction tolerance …

Laterally Loaded Pile Cap Connections
… appropriate connection details between driven piles and pile caps. Prior research on the subject suggests that given a proper embedment length, a specialized reinforced connection may not be necessary. Eliminating these costly connection details could save thousands of dollars on both labor and …

Idealization of pile to pile-cap connection with respect to lateral loads
… thesis is concerned with study of behavior of pile to pile-cap connection with respect to lateral loads. In this connection prestressed precast concrete piles and reinforced concrete pile caps were given particular attention.

Impact of Jet Grouting on the Lateral Strength of Soil Surrounding Driven Pile Foundations
… used to strengthen the soft soil surrounding the piles and the pile cap of two full-scale driven pile foundations. Soilcrete columns, created by jet grouting, were placed underneath the pile cap and surrounding the piles of the first foundation. Two rows of soilcrete columns were placed around the …

Three-Dimensional Analysis of Geogrid Reinforcement used in a Pile-Supported Embankment
Pile-supported geogrid-reinforced embankments are an exciting new foundation system that is utilized when sites are limited by a soft soil or clay. In this system, an embankment is supported by a bridging layer, consisting of granular fill and one or multiple layers of geogrid reinforcement. The …

Dynamic Full-Scale Testing of a Pile Cap with Loose Silty Sand Backfill
Pile caps are used in foundation design to aid multiple single piles to act as a pile group to resist lateral forces that may cause overturning moments. The pile cap and pile group resist these forces by pile-soil-pile interaction, base and side friction along the pile cap-backfill interface, and …

Design of Bridging Layers in Geosynthetic-Reinforced Column-Supported Embankments
… in column-supported embankments can be driven piles, vibro-concrete columns, deep-mixing-method columns, stone columns, or any other suitable type of column. A bridging layer consisting of several feet of sand or sand and gravel is also used to help transfer the embankment load to the columns. …

The axial behaviour of piled foundations in liquefiable soil
… The axial resistance which can be mobilised by piled foundations in liquefiable soils when subjected to strong shaking remains highly uncertain, and a number of piled foundations have failed in strong earthquakes as recently as 2011 . The lack of visible foundation distress in many such cases …

Flood Disaster Resilient Bridge Structures For Sustainable Bridge Management Systems
… bridge girder-deck superstructure, bearings, pile caps and piers. The numerical results of finite element simulation shothat the bridge superstructure displaced 2.42 m under the lateral hydrodynamic force of floodwater. The dowel bars inserted at the bottom of each girder end through bearing …

Dynamic Testing of a Full-Scale Pile Cap with Dense Silty Sand Backfill
… dynamic lateral load tests were performed on a pile cap with a dense silty sand backfill condition. Two hydraulic load actuators connected a test pile cap with a reaction cap. The load actuators incrementally loaded the test cap up to 50 mm of displacement. After each load increment, the …

Kinematics-Based Modelling of Deep Transfer Girders in Reinforced Concrete Frame Structures
… as transfer girders in high-rise buildings, pile caps in bridges or other important structural members. Due to their small slenderness, they exhibit shear failure with disturbed deformation patterns differently from slender beams. Many experiments have revealed the complexity of the shear …
