摘要：

This paper describes a working system for the generation of global stiffness matrices whose elements are functions of shape parameters. The Symbolic Finite Element Analysis System (SFEAS) takes a STRUDL-like [R. D. Logcher, J. J. Connor, Jr and M. F. Nelson, ICES STRUDL-II The Structural Design Language Engineering User's Manual, Volume 2 Additional Design and Analysis Features, ICES Users Group, Cranston, RI (1983)] syntax. The important difference between this and STRUDL is that the joint coordinates, material properties, and forces are entered as expressions of various parameters. The result is a K matrix, each element being a function of those same parameters.
