Dissertation/Thesis Abstract

Compression-bending interaction and spring horizontal stiffness in structural arches
by Linares Ghigliotty, Wallison, M.S.C.E., Universidad Politecnica Puerto Rico (Puerto Rico), 2012, 77; 1520208
Abstract (Summary)

Various methods of arch analysis have been used across the history of engineering practice, design and construction. The main goal of some methods is to identify a precise funicular shape in order to define the geometry of the structure. If this geometry is achieved, the structure will work only in compression and the bending moments along the member can be neglected. The objective of this investigation was to analyze the behavior of a reinforced concrete parabolic arch with reduced rise, subjected to a uniform load that will cause a certain thrust on the supports and the study of the compression-bending interaction along it. As part of the investigation a horizontal spring with variable stiffness at the supports were considered, in order to analyze the condition where the arch behave as a curved beam because thrust is lost due to the soil deformation at the abutment-soil interface causing undesirable bending moment along the structure.
