Effect of Geometry Change on the Ultimate Load Carrying Capacity of Two-Pinned Steel Arches

摘要

The intent of this research was to investigate the effects of change in geometry on the load carrying capacity of two-pinned steel arches. For two-pinned arches, methods have been presented to determine the collapse load considering simple plastic theory, simple plastic theory modified for effects of axial force, and simple plastic theory modified for combined effects of axial force and change in geometry. Methods have also been presented to determine deflections due to bending and due to axial force. Using relatively large scale, two-pinned circular steel arches of I cross-section, experimental tests were performed to verify the theoretical considerations of this study. (Author)
