Stress analysis of eave framework

This paper analyzes structure of eave framework made according to the existing technical documentation. In process of parts and profiles joining, MMA (manual-arc) welding process was used. Eave framework is loaded by wind and snow, where self weight of structural parts is also taken into consideration. Finite element method and ANSYS 11.0 software was used for numerical analysis. A beam element from the ANSYS element library, called BEAM 3-D ELASTIC 4 was used. Numerical analysis showed that the structure fulfill all requirements related to the specified loading. Although maximum deflection exceeds the engineer codex for constructions (1/200 of total span), the axial stresses in beams remain in allowed limits. So one can conclude that construction satisfy given criteria.
