Ensoft, Inc., was established in Austin, Texas in 1985 with the principal aim of developing and applying computer-based solutions to complex engineering problems and has since built a strong reputation as a leader in this area. Ensoft has applied advanced technology, much of it based on recent research, in the writing of software for the solution of complex problems that arise in geotechnical and structural engineering. Notable among Ensoft’s computer programs are those that address the analysis and design of foundations employing piles and drilled shafts.
suite of programs was developed by AMPS Technology Company. The AMPS Package is a finite element system that is composed of three modules:
- AMPSolid, a mesh generator;
- AMPView, a pre-processing and post-processing finite-element application; and
- AMPSol, a nonlinear finite-element solver.
The AMPS Package is a finite element system that is composed of three modules.The programs are implemented to run on a personal computer, under all current Windows operating systems.
The APILE software is used to compute the axial capacity, as a function of depth, of a driven pile in clay, sand, or mixed-soil profiles. The main computational methods used by APILE are those established by the American Petroleum Institute (API) in their manual on recommended practice, API-RP2A. The procedures from API have been adopted by a number of organizations.
ATENA is a computer program system for nonlinear finite element analysis of concrete and reinforced concrete structures. The ATENA program system consists of a set of individual programs and program modules for both 2D and 3D analysis.
The design of foundation for vibrating machines requires an accurate prediction of the foundation response. The method of analysis is complex because it involves the dimension and geometry of the machine foundation, the embedment effect, the material and radiation damping of soils, variation of soil properties with depth, and the interaction effect between the foundation and soils
Program DynaPile was developed to compute the dynamic stiffness of single piles or pile groups. The piles can be either floating piles or end-bearing piles. Vertical, horizontal and rocking dynamic stiffnesses will be generated by the program. The program will also generate the group reduction factors for pile groups under small excitation conditions
is a state-of-the-art program for the design and analysis of precast, prestressed concrete bridges girders made continuous by adding a composite slab with a diaphragm over the bridge piers. EnBeamC
conforms to the '97 AASHTO Standard Specifications for Bridges.
The program is aimed at the solution under static loading of two classes of problems encountered in structural engineering: a soil-supported mat or a structural slab. The mat or structural slab is modeled with linear finite elements. The shape may be rectangular, round, or irregular and the thickness may vary.
GROUP has been well accepted as an useful design tool for analyzing the behavior of piles in a group subjected to both axial and lateral loadings. The program was developed to compute the distribution of loads (vertical, lateral, and overturning moment in up to three orthogonal axes) from the pile cap to piles arranged in a group.
LPILE Plus is a special purpose program based on rational procedures for analyzing a pile under lateral loading. The program computes deflection, shear, bending moment, and soil response with respect to depth in nonlinear soils. Components of the stiffness matrix at the pile head may be computed internally by the program to help the users in their super-structure analysis.
PileGPw is an interactive software program developed to provide the distribution of load and computation of axial deformation of the piles within a pile group. This program is based on the elastic analyses provided by Randolph and Wroth (see reference) for single piles and a pile group under axial loads only. PileGPw can analyze regularly or variably spaced piles in any group configuration as long as locations can be described by a coordinate system. The piles may be of variable diameters; however, all piles in the analysis must be of the same length. This program can provide the distribution of loads within a group with a rigid cap and also the distribution of load within a group utilizing a flexible pile cap. Pile caps other than rigid can be modeled by introducing individual pile-head settlements.
is a unique program for the analysis and design of partially restrained moment connections for steel frame structures. PRConn
allows the user visually to describe the connection details of 36 different types of partially restrained moment connections.
The theoretical concepts used in the PYWALL software extends
beyond the conventional method of analysis and design of flexible
retaining walls based on limit-equilibrium theory. As a difference to
conventional pratice, the PYWALL method does not ignore the effects of soil-structure interaction.

For 2D elastic analysis to 3D nonlinear analysis.The S-Frame is developed by SOFTEK Services Ltd.The program is implemented to run on a personal computer, under all current Windows operating systems.
SHAFT is used to compute the axial capacity and the short-term, load versus settlement curves of drilled shafts in various types of soils. SHAFT v5.0 can analyze drilled-shaft response in six types of strata: i) clay - cohesive geomaterial, ii) sand - cohesionless geomaterial, iii) clay-shale, iv) strong rock, v) gravel - cohesionless IGM, and vi) weak rock - cohesive IGM. The program allows for any combination of soil layers to be placed in a layered profile.
Various versions of Program STABL have been well accepted as useful tools for analyzing the stability of slopes. However, the series adopts a command-line format for data entry which is inconvenient for infrequent users. The computer
program STABLPRO has been developed specifically for users to ease their modeling process and to enhance the graphical observation of slope boundaries and critical slip surfaces. This computer program has been written in 32-bit programming code compatible with Windows 98, 2000 and XP platforms.
TZPILE v2.0 implements the well-known method of soilstructure interaction, commonly called the t-z method, where t-z curves are used for side resistance and q-w curves are used for load transfer in end bearing. The t-z and q-w curves can be internally-generated for both driven piles and drilled shafts
with the input of information on the supporting soil and on the geometry of the pile.
UC-win/Road is a program that is used to generate and present a visible

applications such as city planning, traffic simulations, and
construction demonstrations. The extensive features and visual options

and manipulated in real time.
UTEXAS4 is a computer software application for computing the stability of earth and earth-rock slopes and embankments. UTEXAS4 is written and maintained by Dr. Stephen G.
