PLAXIS 3D Foundation-Finite Element Code For Soil And Rock Analyses GRAPHICAL INPUT OF PROJECTS A project geometry is modelled using a top view approach. The input of soil data, structures, construction stages, loads and boundary conditions is based on convenient CAD drawing procedures, which allows for a detailed and accurate modelling of the major geometry. From this geometry a 3D finite element mesh is generated. BORE HOLES Soil layers are defined by means of bore holes. Multiple bore holes can be placed in the geometry to define a non-horizontal soil stratigraphy or an inclined ground surface. Plaxis automatically interpolates layer and ground surface positions in between the bore holes. WORK PLANES Structures are defined in horizontal work planes. Multiple work planes can be defined to create complex foundations, multi-storey basements and relevant parts of the upper structure. AUTOMATIC MESH GENERATION The Plaxis 3D Foundation program allows for an automatic generation of unstructured 2D finite element meshes based on the top view. The 2D Mesh generator is a special version of the Triangle generator. There are options for global and local mesh refinement. From this 2D mesh, a 3D mesh is automatically generated, taking into account the soil stratigraphy and structure levels as defined in the bore holes and work planes. VOLUME ELEMENTS Quadratic 15-node wedge elements are available to model the deformations and stresses in the soil. Due to non-horizontal soil stratigraphy, these elements may degenerate once to 13-node volume elements or twice to 10-node tetrahedral elements. BEAMS Foundations may involve structural objects like walls, floors and beams. A special type of beam element can be used to model slender one-dimensional objects with a significant flexural rigidity. The stiffness of these elements is defined using elastic stiffness properties or non-linear elastic deformation curves. WALLS AND FLOORS Special plate elements can be used to model raft foundations, basements, walls and floors of buildings, as well as other parts of structures. The behaviour of these elements is defined using elastic stiffness properties or non-linear elastic deformation curves (M-ê and N-å diagrams). INTERFACES These joint elements are automatically added to walls to allow for a proper modelling of soil-structure interaction. Interfaces may be used to simulate, for example, the thin zone of intensely shearing material at the contact between a wall and the surrounding soil. Values of interface friction angle and adhesion that are not necessarily the same as the friction angle and cohesion of the surrounding soil and may be assigned seperately to these elements. PILES Circular and square piles can be defined using a pile designer. Solid piles are composed of volume elements whereas hollow piles are composed of wall elements. Pile-soil interaction can be modelled using interfaces around the pile. LOADS Plaxis 3D Foundation allows for various types of loads (point loads, line loads, distributed loads) that could be applied in the model. Different loads and load levels can be activated independently in each construction stage. Soil Behaviour: Soil behaviour back to top MOHR-COULOMB MODEL This robust and simple non-linear model is based on soil parameters that are known in most practical situations. Not all non-linear features of soil behaviour are included in this model, however. The Mohr-Coulomb model may be used to compute realistic bearing capacities and collapse loads of footings, as well as other applications in which the failure behaviour of the soil plays a dominant role. HARDENING SOIL MODEL As a general second-order model, an elastoplastic type of hyperbolic model is available, which is called the Hardening Soil model. This model allows for plastic compaction (cap hardening) as well as plastic shearing due to deviatoric loading (friction hardening). In comparison with the Mohr-Coulomb model the unloading behaviour of the soil is better taken into account. The Hardening Soil model may be used to calculate realistic pressures below basements and raft foundations and behind soil retaining structures. More detailed information on this model can be found in the Material Models Manual. STRUCTURAL BEHAVIOUR Structural behaviour may be defined as linear elastic material orthotropy or as non-linear elastic force-deformation curves. This applies to beams, walls, floors and springs. Geometric orthotrophy of plates with a particular profile can also be emulated to a certain extent. STEADY-STATE PORE PRESSURE Complex pore pressure distributions may be generated on the basis of the input of water levels or pore pressure distributions in the bore holes. Plaxis 3D Foundation is a finite element package intended for the three-dimensional deformation analysis of foundation structures. Foundations form the interaction between an upper structure and the soil. Settlements depend on local soil conditions and on the construction method. Especially for pile-raft foundations there is an important interplay between the pile, the raft and the soil to support the forces from the upper structure. In this interplay deformations are a key factor. Such a situation can only be analysed effectively by means of three-dimensional finite element calculations in which proper models are incorporated to simulate soil behaviour and soil-structure interaction. The Plaxis 3D Foundation program offers these facilities. A brief summary of the most important features is presented below. EXCESS PORE PRESSURE Plaxis distinguishes between drained and undrained soils to model permeable sands as well as almost impermeable clays. Excess pore pressures are computed when undrained soil layers are subjected to loading.

Spss 16.1 SPSS (originally, Statistical Package for the Social Sciences) was released in its first version in 1968 after being founded by Norman Nie, then a political science postgraduate at Stanford University,[1] and now Research Professor in the Department of Political Science at Stanford and Professor Emeritus of Political Science at the University of Chicago.[2] SPSS is among the most widely used programs for statistical analysis in social science. It is used by market researchers, health researchers, survey companies, government, education researchers, marketing organizations and others. In addition to statistical analysis, data management (case selection, file reshaping, creating derived data) and data documentation (a metadata dictionary is stored with the data) are features of the base software. Statistics included in the base software: * Descriptive statistics: Cross tabulation, Frequencies, Descriptives, Explore, Descriptive Ratio Statistics * Bivariate statistics: Means, t-test, ANOVA, Correlation (bivariate, partial, distances), Nonparametric tests * Prediction for numerical outcomes: Linear regression * Prediction for identifying groups: Factor analysis, cluster analysis (two-step, K-means, hierarchical), Discriminant The many features of SPSS are accessible via pull-down menus or can be programmed with a proprietary 4GL command syntax language. Command syntax programming has the benefits of reproducibility and handling complex data manipulations and analyses. The pull-down menu interface also generates command syntax, though the default settings have to be changed to make the syntax visible to the user. Programs can be run interactively, or unattended using the supplied Production Job Facility. Additionally a "macro" language can be used to write command language subroutines and a Python programmability extension can access the information in the data dictionary and data and dynamically build command syntax programs. The Python programmability extension, introduced in SPSS 14, replaced the less functional SAX Basic "scripts" for most purposes, although SaxBasic remains available. In addition, the Python extension allows SPSS to run any of the statistics in the free software package R. From version 14 onwards SPSS can be driven externally by a Python or a VB.NET program using supplied "plug-ins". SPSS places constraints on internal file structure, data types, data processing and matching files, which together considerably simplify programming. SPSS datasets have a 2-dimensional table structure where the rows typically represent cases (such as individuals or households) and the columns represent measurements (such as age, *** or household income). Only 2 data types are defined: numeric and text (or "string"). All data processing occurs sequentially case-by-case through the file. Files can be matched one-to-one and one-to-many, but not many-to-many. The graphical user interface has two views which can be toggled by clicking on one of the two tabs in the bottom left of the SPSS window. The 'Data View' shows a spreadsheet view of the cases (rows) and variables (columns). The 'Variable View' displays the metadata dictionary where each row represents a variable and shows the variable name, variable label, value label(s), print width, measurement type and a variety of other characteristics. Cells in both views can be manually edited, defining the file structure and allowing data entry without using command syntax. This may be sufficient for small datasets. Larger datasets such as statistical surveys are more often created in data entry software, or entered during computer-assisted personal interviewing, by scanning and using optical character recognition and optical mark recognition software, or by direct capture from online questionnaires. These datasets are then read into SPSS. SPSS can read and write data from ASCII text files (including hierarchical files), other statistics packages, spreadsheets and databases. SPSS can read and write to external relational database tables via ODBC and SQL. Statistical output is to a proprietary file format (*.spo file, supporting pivot tables) for which, in addition to the in-package viewer, a stand-alone reader is provided. The proprietary output can be exported to text or Microsoft Word. Alternatively, output can be captured as data (using the OMS command), as text, tab-delimited text, HTML, XML, SPSS dataset or a variety of graphic image formats (JPEG, PNG, BMP and EMF). Add-on modules provide additional capabilities. The available modules are: * SPSS Programmability Extension (added in version 14). Allows Python programming control of SPSS. * SPSS Data Validation (added in version 14). Allows programming of logical checks and reporting of suspicious values. * SPSS Regression Models - Logistic regression, ordinal regression, multinomial logistic regression, and mixed models (multilevel models). * SPSS Advanced Models - Multivariate GLM and repeated measures ANOVA (removed from base system in version 14). * SPSS Classification Trees. Creates classification and decision trees for identifying groups and predicting behaviour. * SPSS Tables. Allows user-defined control of output for reports. * SPSS Exact Tests. Allows statistical testing on small samples. * SPSS Categories * SPSS Trends * SPSS Conjoint * SPSS Missing Value Analysis. Simple regression-based imputation. * SPSS Map * SPSS Complex Samples (added in Version 12). Adjusts for stratification and clustering and other sample selection biases. SPSS Server is a version of SPSS with a client/server architecture. It has some features not available in the desktop version, such as scoring functions |
