STRAP – A COMPUTER CODE FOR STATIC AND DYNAMIC STRUCTURAL ANALYSIS AND STUDIES MADE USING THE CODE

摘要

The computer code STRAP (STRuctural Analysis Package), developed to perform static and dynamic analyses of reactor structural systems, is described. The code uses the finite element method to model a structure and an uncoupled modal summing procedure to perform the dynamic analysis. STRAP is a three-dimensional structural analysis code and can be used in the static and dynamic analyses of structures having up to 250 degrees of freedom.nStudies on structural modeling techniques were made using the code, and guidelines are given for the modeling process.
