Load Path Analysis of Structures and Generalized Support Conditions

Abstract

A concept of a parameter U* has been introduced by the authors to express load transfer paths in a structure. In this paper, a new extended expression of U* is introduced, and it is shcown that the new parameter can be applied to structures with complicated multiple support conditions. The present expression that is derived by matrix formulation of internal stiffness and initial deformation includes the definition of U* in the previous report. Examples of U* calculation for structures with multiple support conditions are demonstrated. Calculation results for a simple structure and an actual truck cab body show the effectiveness of the present method of U* calculation.
