FB-MultiPier is a nonlinear finite element analysis program capable of analyzing multiple bridge pier structures interconnected by bridge spans. The full structure can be subjected to static analysis, AASHTO load analysis, response spectrum analysis, and time-history analysis. Each pier structure is composed of pier columns and cap supported on a pile cap and piles/shafts embedded in soil. This program couples nonlinear structural finite element analysis with nonlinear soil resistance models for axial, lateral, rotational, and torsional soil behavior to provide a robust system of analysis for coupled bridge pier structures and foundation systems. FB-MultiPier allows for finite element model generation based on graphical input and parametric descriptions of the structure and foundation systems. This allows the engineer to work directly with design parameters and improves efficiency in model creation and interpretation of analysis results.
The FB-Deep computer program is a Windows-based program used to estimate the static axial capacity of drilled shafts and driven piles. The drilled shaft methodology is based upon Federal Highway Administration reports. Driven pile methodology utilizes two types of analyses: SPT and CPT. SPT methodology is based on empirical correlations between cone penetrometer tests and standard penetration tests for typical Florida soil types. Unit end bearing resistance and unit skin friction resistance versus SPT N values are given in the FDOT research bulletin RB-121, for the different soil types. Driven pile capacity calculated using CPT data can be determined by three separate methods. The first method is the Schmertmann method proposed by Schmertmann in 1978 (AASHTO LRFD Bridge Design Manual). The second method is the LCPC method proposed by Bustamante and Gianeselli for the French Highway Department in 1982. The third method is the UF method proposed by Bloomquist, McVay and Hu for the FDOT in 2007.
Pile Technician was developed for the FDOT to provide a fast and efficient manner of entering Pile data to calculate payment for work performed by the contractor.
ATLAS is an analysis/design program which is used for the analysis and design of signal lights and signs supported by the dual cable system. The analysis consists of an iterative technique which is a combination of the Force Density Method (FDM) and the Direct Stiffness Method (DSM). The FDM is ideal for the analysis of cable structures whereas the DSM is the most widely used technique for the analysis of framed structures. The nature of the structures under consideration lead to the development of this analysis technique which is a combination of the two methods. ATLAS handles the wind loading in a realistic manner. It allows the user to specify the wind speed as well as the areas of the signal lights or signs, parallel to the X and Y axis. In doing so the program calculates the applied loads on the corresponding nodal points internally, based on the specified element areas of the LIGHT elements in each plane. The loads are calculated in each cycle of the nonlinear process. Therefore, the applied loads in each cycle change with the rotation angle of the light. Thus the load are more realistic since they change with the swinging of the light. The angle change of the light also causes an uplift load at the cable nodal points.

NASTRAN source code is integrated in a number of different software packages, which are distributed by a range of companies.
Seismic analysis is a subset of structural analysis and is the calculation of the response of a building structure to earthquakes. It is part of the process of structural design, earthquake engineering or structural assessment and retrofit in regions where earthquakes are prevalent.
In geotechnical civil engineering, the p-y method is a method of analyzing the ability of deep foundations to resist loads applied in the lateral direction. This method uses the finite difference method and p-y graphs to find a solution. P-y graphs are graphs which relate the force applied to soil to the lateral deflection of the soil. In essence, non-linear springs are attached to the foundation in place of the soil. The springs can be represented by the following equation:
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths.
The finite element method (FEM), is a numerical method for solving problems of engineering and mathematical physics. Typical problem areas of interest include structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. The analytical solution of these problems generally require the solution to boundary value problems for partial differential equations. The finite element method formulation of the problem results in a system of algebraic equations. The method approximates the unknown function over the domain. To solve the problem, it subdivides a large system into smaller, simpler parts that are called finite elements. The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem. FEM then uses variational methods from the calculus of variations to approximate a solution by minimizing an associated error function.

Slope stability analysis is performed to assess the safe design of a human-made or natural slopes and the equilibrium conditions. Slope stability is the resistance of inclined surface to failure by sliding or collapsing. The main objectives of slope stability analysis are finding endangered areas, investigation of potential failure mechanisms, determination of the slope sensitivity to different triggering mechanisms, designing of optimal slopes with regard to safety, reliability and economics, designing possible remedial measures, e.g. barriers and stabilization.
SVSLOPE is a slope stability analysis program developed by SoilVision Systems Ltd.. The software is designed to analyze slopes using both the classic "method of slices" as well as newer stress-based methods. The program is used in the field of civil engineering to analyze levees, earth dams, natural slopes, tailings dams, heap leach piles, waste rock piles, and anywhere there is concern for mass wasting. SVSLOPE finds the factor of safety or the probability of failure for the slope. The software makes use of advanced searching methods to determine the critical failure surface.
