Instability Analysis of Damaged Pile Due to Static or Dynamic Overload

static versus dynamic assessment of l2 learners’ reading ability

dynamic assessment according to vygotskys sociocultural theory, states that instruction and assessment are interrelated. using static forms of assessment with second and foreign language students could do more harm than good. many teachers neglect to take account of the complexity involved in learning a second or foreign language and often wonder why learning of a language take so long. thi...

Static and Dynamic Lateral Loading of Pile Groups

Nonlinear Dynamic Analysis of Pile Foundation Subjected to Strong Ground Motion Using Fiber Elements

In this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. In the created model, both pile and surrounding soil are modeled using fiber elements in a practical Beam on Nonlinear Winkler Foundation (BNWF) concept. Herein, the features of DRAIN–3DX finite element software are ...

Extension of Excavation Damaged Zone Due to Longwall Working Effect

In advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. The gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (EDZ) above the gate roadway and 2) loading effect due to the caving zone (CZ) above the longwall w...

Dynamic and Static Properties of Pile- Soil Interface

The research progresses in static and dynamics tests, constitutive models, interface elements, model tests and field tests of pile soil interface are summarized, and the problems and deficiencies in the current research are analyzed. It is pointed out that research on the dynamic characteristics of pile soil interface widely seen in practical engineering are in lack. Especially, big size experi...
