Abstract
In this study, concrete-filled tube (CFT) column-to-foundation connections were investigated experimentally to improve the design of their structural details. Initially, five different types of foundation connections, which were classified according to the design parameters incorporating the types of anchor bolts, shear connectors, base members, and reinforced bars used, were fabricated. After conducting structural experiments on these foundation models, the performance and capacity of the individual model cases from the test results were compared with each other. The test results showed that some of the test models designed according to current design guidelines had problems related to the structural details. Therefore, this study proposed an adequate design methodology to improve the performance of foundation components, such as high tension bolt, base frame members, and embedded plate. An analytical investigation of the force-deformation relationship as well as the characteristic strains distributed over the individual foundation components was performed.
Highlights
Design and construction methods have been improved by the development of new construction technologies in the field
Most bridge piers have recently been designed with various types of concrete-filled tube (CFT) columns, which have structural advantages with regard to durability, strength and sustainability
This study focused mainly on new structural details concerning the design methodology for circular
Summary
Design and construction methods have been improved by the development of new construction technologies in the field. Road bridges, as a representative civil engineering structure, have become longer because of the demand for more space, and are constructed using a range of design methodologies. Bridge piers need to be designed with sufficient strength to support the superstructure of such long-span bridges. Many piers upholding the road bridge have been constructed on space-intensive downtown area. For these reasons, most bridge piers have recently been designed with various types of concrete-filled tube (CFT) columns, which have structural advantages with regard to durability, strength and sustainability. Concrete foundations, as the substructure of a bridge that transfers the loads from the pier to the ground, should be erected using reasonable design and construction methods to secure superior capacity and stable performance
