Micro-Computer Based Dynamic Analysis of Linear Undamped Plane Frame Structures.

Abstract

This paper presents an assimilation of mathematical models and solutions needed in order to develop computer based analysis of dynamic structures. Using the variational formulation and a direct integration technique, a dynamic finite element model is developed. Modal analysis of unknown displacements of the structure, and the dynamic reduction of the structure are presented as alternative solutions. A system of micro-computer based programs which apply the presented solution techniques is described. The system of programs support varying cross sections of frame members, application of static, harmonic and non-harmonic loading conditions, and node displacements in the form of uniform base motion or independent node movement. Additional keywords: Matrices(mathematics); Flow charting; Numerical integration. (Author)
