- ADAP - Legacy software from 1973 for linear static and dynamic analysis of arch dam-foundation systems. Source code in FORTRAN and related reports can be downloaded from the earthquake engineering online archive maintained by University of California Berkeley. ADAP: Static and Dynamic Analysis of Arch Dams Clough, Ray W.; Raphael, Jerome M.; Mojtahedi, Soheil Department of Civil Engineering, University of California, Berkeley, 1973, ADAP is a finite element program capable of performing linear static and dynamic analysis of arbitrary arch dam-foundation systems. Most of the logical features and many of the subroutines of the computer program SAP are utilized in this program. Special features primarily associated with preparation of input data are incorporated to make it more suitable for arch dam analysis. Three different element types are included in the program; these are considered to be the most suitable in this application. The program is organized in such as way that, if desired, new elements can be included easily. A finite element mesh is automatically generated from a minimum amount of input information. In each problem any one of the following types of analysis can be requested: (1) static analysis - the program is capable of handling an arbitrary combination of gravity, water pressure, and temperature loading conditions, and concentrated loads at any node; (2) evaluation of natural frequencies and mode shapes - if these are not available for input they are automatically evaluated as part of (3) or (4); (3) response history analysis - using a step-by-step integration scheme assuming the accelerations to vary linearly within each time step; and (4) response spectrum analysis - which results in estimated maximum values for displacements and stresses.
- ANSRuop - The ANSRuop computer program is specialized structural analysis software, designed for scientific research as well as to aid practicing engineers. Its capabilities include static and dynamic, linear and non-linear analysis of structures. A wide spectrum of structures can be analysed through generalized modeling, the program is targeted towards the displacement- and deformation-based assessment of the non-linear seismic responce of reinforced concrete buildings and bridges. In this direction, the relevant rules and expressions of Eurocode 8 Part 3 as well as the Greek Code for interventions on existing structues are built into the program.
- CAL-91 - Legacy software from 1991 to facilitate teaching of structural analysis concepts. Source code in FORTRAN and related reports can be downloaded from the earthquake engineering online archive maintained by University of California Berkeley.
CAL-91: Computer Assisted Learning of Structural Analysis
Wilson, Edward L.
Department of Civil Engineering, University of California, Berkeley, 1991,
The basic purpose of the CAL language is to bridge the gap between traditional methods of teaching structural analysis and the use of automated structural analysis programs. As a result of using CAL-91, it is hoped that engineers will understand the theory and approximations which are used in modern structural analysis programs. CAL-91 is designed to interpret a sequence of commands which are supplied by the user. The commands can be given directly in an "interactive mode," or the program can read the commands from a "batch data file." The input has been redesigned so all commands, array names, and data are in free- field form. Commands for matrix analysis, direct stiffness structural analysis, and dynamic response analysis are possible. The program is written in standard FORTRAN 77 and will operate on small microcomputers or large mainframe computers. Printer plots of results can be produced. CAL-91 is used to perform linear dynamic analysis of small structural systems. It is possible to solve the following types of dynamic problems: 1. Evaluation of free-vibration mode shapes and frequencies. 2. Automatic generation of Ritz vectors to be used in mode superposition analysis or response spectra analysis. 3. Mode superposition analysis due to arbitrary loading. 4. Response spectra analysis due to earthquake loading. 5. Step- by-step analysis of structural systems with arbitrary viscous damping. - FB-MultiPier - The FB-MultiPier analysis program is a nonlinear finite element analysis program capable of analyzing multiple bridge pier structures interconnected by bridge spans. The full structure can be subject to a full array AASHTO load types in a static analysis or time varying load functions in a dynamic analysis. Each pier structure is composed of pier columns and cap supported on a pile cap and piles/shafts with nonlinear soil. This analysis program couples nonlinear structural finite element analysis with nonlinear static soil models for axial, lateral and torsional soil behavior to provide a robust system of analysis for coupled bridge pier structures and foundation systems. FB-MultiPier performs the generation of the finite element model internally given the geometric definition of the structure and foundation system as input graphically by the designer. This allows the engineer to work directly with the design parameters and lessens the bookkeeping necessary to create and interpret a model.
