A COMPUTER PROGRAM FOR THE DYNAMIC BLAST RESPONSE OF BOX-TYPE STRUCTURES

Abstract

The report describes the development of two digital computer programs. Both programs analyze the response of a multi-cell rectangular box- structure to external dynamic loads. The programs use the principle of finite elements to represent the box-structure and solve the equations of equilibrium by means of a Gaussian elimination procedure. The first of the two programs considers the dynamic response of the box-structure with its material properties remaining linear. The output consists of displacements, moments and stresses. Also, response spectra may be generated at equipment attachment points within the structure. The second program calculates the dynamic response with the added provision that when moments in any plate exceed a predetermined yield value, that plate will not accept any increase in loads normal to its plane. However, it is assumed that the plate would still be able to carry the inplane diaphragm forces. A synoptic review of selected literature pertaining to the failure modes and failure loadings of two-way slabs is presented at the end of the report.
