Modular Modeling Approach for Analysis of Cellular Beams

Abstract


This paper presents the modular modeling approach adapted for the analysis of a cellular beam. These beams can be very useful for reducing the overall floor thickness in order to improve the Architectural design of a building. The cellular beam is made of a steel I-section with a total of 32 holes throughout its length. The finite element model of the beam is divided into 32 partitions
and each partition is analyzed on a different processor. This partitioning method is based on a domain decomposition technique using dual partition super-elements. The analysis results are compiled and it is shown that with the help of the partitioning method, the nonlinear analysis of cellular beams has become more efficient and more accurate.
