Seismic Design of Concrete-Filled Circular Steel Bridge Piers
The adequacy of the existing design provisions for concrete-filled steel pipes subjected to axial forces and flexure is reviewed by comparing the strengths predicted by the CAN/CSA-S16.1-M94, AISC LRFD 1994, and the Eurocode 4 1994 codes and standards against experimental data from a number of investigators. New proposed design equations are then developed, in a format compatible with North Ame...
متن کاملCyclic Testing of Concrete-Filled Circular Steel Bridge Piers having Encased Fixed-Based Detail
To investigate their adequacy as energy dissipating elements during earthquakes, this paper reports on cyclic inelastic tests executed to determine the maximum strength and ductility of four concrete-filled circular steel piers joined to a foundation detail proposed to develop the full composite strength at the base of these columns. Column diameters considered were 324 and 406 mm, with D/t rat...
متن کاملReinforced Concrete Bridge Piers Subjected to Reversed Cyclic Loading
Sixteen large-scale reinforced concrete specimens without web reinforcements were tested to study the behavior of typical bridge piers subjected to deflection reversals that were large enough to cause extensive yielding of the longitudinal reinforcement. The different parameters considered included shear spanto-depth ratio, percentage of longitudinal reinforcement, frequency of the applied load...
متن کاملExperimental Investigation of Multihazard Resistant Bridge Piers Having Concrete-Filled Steel Tube under Blast Loading
This paper presents the development and experimental validation of a multizard bridge pier concept, i.e., a bridge pier system capable of providing an adequate level of protection against collapse under seismic and blast loading but not acting simultaneously . A multicolumn pier-bent with concrete-filled steel tube CFST columns is the proposed concept, and the adequacy of this system is experim...
متن کاملDynamic Analysis of Multihazard-Resistant Bridge Piers Having Concrete-Filled Steel Tube under Blast Loading
Research was conducted to analytically investigate the blast-response and behavior of multihazard-resistant bridge piers having circular-shaped, concrete-filled steel tube (CFST) columns. Two different analysis methods, namely a single-degree-of-freedom (SDOF) dynamic analysis and a fiber-based dynamic analysis, were used for this purpose and calibrated with the maximum residual deformations ob...
