In this paper, inelastic pile-soil-structure interaction under static loading is presented by using finite element and boundary element methods. Linear beam column finite elements are used to model the piles and structural elements. Nonlinear soil is modeled by using nonlinear springs along the piles. Modified Özdemir’s nonlinear model is implemented for springs and systems of equations are cou...

The conventional strengthening strategy on the connection between the steel pile cap and reinforced concrete footing requires a series of complicated processes such as the distribution of reinforcing bars, their anchorage into concrete, and the usage of shear keys. This study investigates the structural performance of steel pile caps strengthened with newly proposed perfobond shear connectors s...

The principle and method of self-balancing test are introduced briefly. In this article, through comparison common Q-S curve equivalent transformation to transform from the balance measured load-displacement for traditional load - displacement curve, puts forward advantages disadvantages each, three bored piles in static pile reaction detect vertical compressive ultimate bearing capacity single...

to increase the safety of structures against strong ground motions and their life due to environmental issues on the earth and saving in terms of materials, it is necessary to expand and upgrade seismic resistant systems. however, more cost-effective systems which have sufficient influence on the seismic performance of structures and also more compatibility with the regional conditions, will be...

Estimating pile group efficiency for open-ended steel piles in small arrangements is a challenging task designers. This paper reports on the large-scale experimental campaign performed BorWin gamma offshore converter platform, which involved single and two-pile systems scale of 1:10. The works included installation, dynamic end-of-driving tests, restrike static load tests pair groups densely co...

The article presents the results of static tests a strip foundation fragment, strengthened with bored pile, which has an enlarged pile base at its lower end. To evaluate obtained, were also carried out for load fragment without strengthening and separately located base. According to data obtained during load, dependence graphs constructed: settlements from pressure under toe settlement indentat...

The high-temperature hardness test has a wide range of applications, but lacks test standards. The purpose of this study is to develop a finite element method (FEM) model of the relationship between the high-temperature hardness and high-temperature, quasi-static compression experiment, which is a mature test technology with test standards. A high-temperature, quasi-static compression test and ...
