Metal powder 3D printing technology is gaining popularity due to the possibility of producing structural elements complex geometry, which production with methods used so far difficult or impossible obtain. An example a material in parts by additive method 316L steel, bone support screws, surgical tools and needles, other industries for exhaust manifolds, furnaces heat exchangers. The study inve...

This study is to evaluate the behavior of integral and segmental specimens through static and cyclic tests. Integral specimens were made with the same size to be compared with segmental specimens that were made by connected precast members. To evaluate its bending performance and serviceability, 1 integral and 3 segmental specimens were tested under static load. And 1 integral and 2 segmental s...

Pile foundation systems are used in India many projects such as metro and railways, flyovers, multi-story buildings. The pile transfers superstructure load to the substructure, i.e. rock layers by means of skin resistance end-bearing resistance. In this study, an attempt is made observe performance socketed piles soft rock. A series small-scale model laboratory studies have been conducted using...

The evaluation of liquefaction effect on the dynamic moment of stabilizing piles is potentially significant. Based on the dynamic centrifuge modeling of a slope reinforced with a row of copper model pile, this paper not only analyzed the response of dynamic pore pressure, earthquake deformation and macroscopic phenomenon measured in the response of the reinforced slope, but also simulated the r...

Considering the pile-slab subgrade project of Hangzhou-Huang Shan Passenger Dedicated Line as basis, this paper conducts a 1:10 large-scale indoor model test for horizontal bearing capacity structure in steep mountainous areas to study distribution stress, soil pressure and structural deformation analyze failure mode slope. The research shows that when with double-row is subjected loading slope...

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...

Despite widespread research effort in recent years, design methods to estimate the shaft resistance of displacement piles continue to rely heavily upon empirical correlations. In an attempt to achieve a more reliable design approach several researchers have assembled databases of instrumented pile load tests and used these to propose new design methods e.g. American Petroleum Institute (API-200...
