Computer Program for Two-Dimensional Analysis of U-Frame or W-Frame Structures (CWFRAM). (User's Guide)

Abstract

The interactive computer program CWFRAM, described in this user's guide, performs an analysis of a two-dimensional slice of a U-frame or W-frame structure. The program functions in two modes, equilibrium and fram analysis. In the equilibrium mode, the program converts soil and/or water effects to surface loads on the structure, determines the resultants of all applied loads, and determines the necessary base-reaction distribution to equilibrate the external loads. In the frame analysis mode, a model of the structure is formulated and displacements and internal forces throughout the structure are determined from a linearly elastic analysis. Information regarding the response of the structure is provided by this program with no actual design functions nor judgment offered as to the quality of the structural performance. Under certain conditions outlined herein, an analysis of a two-dimensional slice provides comparatively reliable indications concerning the behavior of the three-dimensional systems.
