The solution of static problem of arch structures by the difference equation method

Rakowski J., Łasecka-Plura M.

Foundations of Civil and Environmental Engineering

2006

No. 8

99-110

The solution of a bending problem for a circular arch loaded by nodal forces has been presented herein. The considered structure is divided into a regular mesh of identical finite elements. Equilibrium equations have becnwriiten in the form of three difference equations. The solution has beenobtained in the analytical closed form which does not depend on mesh density.
