Abstract

This study considers loadings on the multi-layer web frame structure and uses a novel method of the modified analytical hierarchy process (AHP) combined with modified theory of inventive problem solving (TRIZ) clustering to perform the creative structure design. The engineering knowledge of multi-layer web frame structure comprises such issues as vibration, yielding and buckling strength. Using the modified AHP, this study firstly applies the ratios of occurrence numbers of related keywords on different hierarchies to analyze the techniques and functions of multi-layer web frame structure, and finds out the priority order of feasible design decisions. Furthermore, this study also proposes the application of modified TRIZ clustering method to find out the priority order for TRIZ inventive principles and un-worsened parameter groups by a developed program, and then undergoes the innovation and improvement of local design so as to acquire a better design. In the process of knowledge analysis, this study carries out multi-hierarchy analysis and investigation of the relationship between loads and pillar. Thereafter, this study step by step uses finite element method (FEM) to perform stress verification, and then it completes the innovative design of multi-layer web frame structure.
