Pull-out Experiments with Cohesionless and Cohesive Soils for Reinforcement Application.

A shear-lag model with a cohesive fibre–matrix interface for analysis of fibre pull-out

A shear-lag model with a cohesive fibre–matrix interface has been developed for the analysis of stress transfer between the fibre and the matrix in fibre-reinforced composites in this paper. A bilinear cohesive damage evolution law is used to describe the fibre–matrix interface behaviour. The governing equations for the interfacial shear stress and the axial stress in the fibre are derived. Acc...

Application of Reinforcement Learning Algorithms for Predicting Taxi-out Times

Accurate estimation of taxi-out time in the presence of uncertainties in the National Airspace System (NAS) is essential for the development of a more efficient air traffic management system. The dynamic nature of operations in the NAS indicates that traditional regression methods characterized by constant parameters would be inadequate to capture variations in taxi-out time across a day. In th...

Title Pile Aging in Cohesive Soils

This technical note presents the results of a field investigation into pile aging in soft clay which was conducted over a period of ten years. Static load tests were conducted after the excess pore pressure generated by the installation of 6 m long driven concrete piles were fully equalised. These tests allowed the time-capacity aging profile to be established. A normalised capacity-time trend ...

Predictive Model for Normalized Shear Modulus of Cohesive Soils

called maximum shear modulus, Gmax. It can be determined by in-situ methods from the measurements of the shear wave velocity, Vs, by means of crosshole, down-hole, up-hole, or surface wave testing. The relationship between maximum shear modulus and shear wave velocity is rigorous: 2 max s G V    where ρ is soil density. This parameter can be also obtained in laboratory by resonant column or ...
