Análise estática não-linear de estruturas marítimas estaiadas em microcomputadores

This work describes a microcomputer program developed for static, non-linear analysis of guyed structures. The program may consider geometrically non-linear space truss elements, using an updated Lagrangean formulation for large displacement analysis. Geometrical and material non-linearities may also be considered for space frame elements. The material non-linearity is due to an explicit elastic-plastic stiffness matrix, which is based on the plastic theory of beams and on a nodal yelding criteria. Catenary equations are used to predict the cable stiffnesses. Routines for hydrodinamic forces were also added. Linear Airy theory is used to compute wave verocity and acceleration. Induced loads on members due to waver and current action are evaluated by Morison Equation. The program is very versatile and performs very well on the analysis of transmission lines with cross rope structures and structures commonly found on offshore engineering.
