| Abstract: | Curved graphs that relate the f/L ratio and the λ = qL3/EIy parameter for clamped arches with the different calculation hypothesis are going to be proposed in this article.It has been necessary to determine the real critical lateral strength of a series of clamped arches considering different calculation hypothesis respect to geometrical linearity and a steel material characteristic.The elastic-plastic material hypothesis with non geometrical linearity considers the existence of residual stresses and initial lateral deflection. |
