User's Guide. Computer Program for Two-Dimensional Dynamic Analysis of U-Frame orW-Frame Structures (CDWFRM)

摘要

This user's guide describes a computer program CDWFRM for dynamic analysis of atwo-dimensional (2-D) slice of a U-frame of W-frame structure. 'CDWFRM' is a companion to the program 'CWFRAM' for static analysis of these structures and relies heavily on the documentation for that program. The program functions in the frame analysis mode, in which a 2-D plane frame model of a pile supported monolithic concrete structure is formulated. The effects of soil and/or water in the model of the system must be explicitly provided by the user with the 'additional weight' facility described subsequently. Displacements and internal forces throughout the structure, including pile forces, induced by an earthquake excitation are determined from a linearly elastic model analysis. This program provides information regarding the response of the structure only, performs no design functions, nor does it attempt to judge the quality of the structural performance.
