Width-dependent characteristics of pile/soil system subjected to lateral force.
This thesis deals with the determination of modulus of subgrade reaction for both sandy and clayey soils surrounding laterally loaded short piles. The initial value of modulus of subgrade reaction determined is based on Terzaghi, Bowles' and Vesic's method. The difference in lateral displacement of …

Interação estaqueamento - meio homogêneo
A genral method of solution for vertically loaded pile groups, embedded in an homogeneous linear elastic medium, is presented in this work, with the intention of predicting displacents, rotations and forces distribution along the piles, considering pile-soil interaction. The present analysis is …

Evaluating the Traffic Speed Deflectometer (TSD) for network-level screening of pavements in Michigan
… load from TSD dual tires loading. Such approach of using equivalent quasi-static FWD load is consistent with the AASHTO procedures for determining the Portland cement concrete (PCC) elastic modulus and modulus of subgrade reaction (composite k-value). A key finding is the recommendation of a 1.25 …

Field monitoring of integral abutment bridge approach slabs
… costs and longer service life. Cracking of approach slabs immediately adjacent to IABs, which requires maintenance, repair, and even premature replacement, has been observed recently at a number of IABs in Illinois. Agency survey across the U.S. indicates that other states have also …

Field investigation of subgrade non-uniformity effects on concrete pavement
The traditional method of designing concrete pavements is through the assignment of a single modulus of subgrade reaction (k-value) to the soil for the section under consideration. It is well known that soil under pavement is not a homogenous, elastic, and isotropic half-space but varies spatially …

The influence of semi-rigid connections on the behaviour of slender structures
In the classical analysis and design of slender frame structures, it is normally assumed that the connections of the structures are either rigidly fixed or perfectly pinned. However, the real situation is that most connections often exhibit semi-rigid characteristics. This no doubt has a …
