STATIC COLLAPSE OF ELASTIC CIRCULAR ARCHES

The static collapse of elastic circular arches is considered. Parametr ic studies of elastic circular arches with different end conditions an d different subtending angles are performed. These arches exhibit a co llapse behavior. These simulations are based on an assumed-stress hybr id, two-node beam element, which is briefly described and then used to study the static collapse of elastic circular arches. The influence o n the collapse mode of deformation of end conditions and arch geometry , as determined by the subtending angle, is discussed.
