The Effect of Axial Selection on Static Solution Results in Heat Affected Non-Prismatic Elementary Frames

In this study, the influence of the bar axis selection on the static solution results was investigated in-plane carrier systems consisting of non-prismatic bar elements (height variable bar elements, also known as hunched, along the axis) in terms of equal or different heat exchange effect. On the sample considered, the non-prismatic elements are considered as straight-axis bars. The results obtained from the classical analysis (the section change is taken into account only at the bending stiffness in this method) and the solution results, which are proposed for non-prismatic elements, obtained by considering the weight axis of the element as a bar axis are compared and the relative differences was detected with differences between two results.
