Dynamic analysis of complex spacial frame systems by the finite element method

Abstract

Numerical simula1ion of complex special frame systems subjected to static load dynamic load and base acceleration is formulated. A finite element model is applied therein the, complex nodes and the foundation influence are considered. Equations of motion are soviet afterontively by step-by-step direct integration and mode superposition method. A number of illustrated  example are computed by the numerical superpose FRADYN), which can be used directly in the field of staeciural design.
