Analysis of fink trussed bents by moment and thrust distribution

Abstract

Before the method of moment and thrust distribution can be applied to trussed bents, certain constants must be determined. These constants can be obtained without too much difficulty as has been shown.

Once these bent constants are known, the moment and thrust distribution may then be performed about an equivalent joint. For Fink type trussed bents the location of this equivalent joint is dependent upon either of two assumptions which make use of the Spagnuolo column and the Maugh equivalent column.

The actual process of the distribution of the thrusts and moments follows the pattern developed by Professor Cross. Care must be taken however in carrying out the procedure to be certain of including all the effects that accompany the balancing process.
