When using embedded piles, however, the conditions of the top of each embedded pile can be selected as free, fixed or pinned. To the writer's knowledge, there is no way of modelling a pile raft with pinned conditions at the pile heads using volume piles. While it is possible to create a half-pile in the pile designer, it is not possible to create a quarter of a pile. The pile group can be modelled as half a group by using one line of symmetry or can be modelled using a quadrant of a group by using two lines of symmetry i. First of all, taking advantage of the symmetry boundaries in PLAXIS can greatly reduce the number of piles you need to model and thus the number of elements in your finite element model assuming the pile group is symmetrical. Lane 5000įor pile groups larger than 40 piles, however, it is possible to model these groups by using a couple of tricks. In order to prevent this stage having any effect on the adopted soil properties, it is advisable that the unit weight of the dummy material is set to 0. One final tip - if the adopted soil model is a nonlinear soil model for e. Pile group loading by placing a compressive or tensile uniform distributed load on the top surface of the pile cap. Pile installation by changing the soil within the volume pile to the properties of concrete.Įxcavation of the dummy material around the piles to the required depth i. Thus the stages of analysis for a free-standing pile group are as follows. The top dummy layer is then excavated so that the piles are left extending above the soil surface. The user then converts the soil within the pile cross-section to the properties of concrete. One trick to get around this is by creating an extra layer of soil above the ground surface a 'dummy' layer. It can be difficult, however, to have these piles extend above the ground surface where there is no soil volume. Smart selection of line elements in PLAXIS 2D Input
Plaxis 2d examples install#
In order to install a pile, PLAXIS first needs a volume of soil to convert to the properties of concrete during the pile installation phase. Both to improve the quality of their products and to transfer the technical knowledge and achievements of the day among the researchers in this field.Post a Comment.
Plaxis 2d examples software#
With its various features, this program is one of the best in the field of geotechnical engineering. plaxis is a company that specializes in geotechnical software and in addition to software, conferences and research seminars around the world. The company’s software is based on a finite element analysis method that is used effectively in two-dimensional and three-dimensional products. The seminars held by Plexiglas are not about the company’s software training, but about the transfer of engineering knowledge among the members. Plaxis 3D Foundation is a software for analyzing the finite element of soil stability and transformation in geotechnical engineering. With its many features, this program fully analyzes geotechnical structures from different angles, and this analysis is based on the scientific and theoretical foundations that the researchers of this scientific branch have achieved. Plaxis 3D Foundation defines complex structures consisting of artificial structures and soil in separation modes, and separate work is possible on each mode. This user-friendly product is designed and has high flexibility in modeling and simulation, has a powerful processing core and performs post-processing processes well.
