摘要

The object of this study was to investigate the effect of axial force on the load carrying capacity of two pinned steel arches. Methods have been presented to estimate the collapse load based on simple plastic theory considering the axial force influence. In caxes where the geometry of the arch and the loading condition is simple, the expression can be conveniently solved and the simple plastic theory collapse load determined. In other cases, a graphical method for solution is more convenient. An estimate of collapse load has been made by reducing the simple plaxtic theory collapse load for the effect of axial force. To verify the theoretical investigations, a series of tests were performed on two-pinned circular steel arch specimens of I cross section with low rise-to-span ratios. (Author)
