Cyclic Behavior of Slab–Wall Connections with Concrete-Filled Steel Tubes Embedded in Wall Piers

نویسندگان

چکیده

Concrete-filled steel tubes (CFSTs) embedded in structural walls can improve the lateral-force resistance of slab–wall structures, but also impede passage and anchorage bars slabs around tubes. Therefore, objective this research is to propose design detailing solve problem, analyze bearing capacity seismic performance joint using design. Two types no-through-tube were put forward for that intersect with CFST-strengthened walls: (1) an anchoring ring (AR) detailing; (2) a direct (DA) detailing. Four concrete specimens these two tested cyclically. It was found connection AR had better ductility energy dissipation compared those DA Nevertheless, more force-transferring capacities, meaning they at transferring force received by shear walls. Overall, both be adopted practice significantly connections, choice which use would depend on specific requirements project.

Non-linear Analysis of Multi-hazard Performance of Cylindrical Concrete Filled Steel Tubes Bridge Piers

Advanced finite element techniques are used to investigate the multi-hazard (earthquake and blast) performance of Concrete-Filled Steel Tubes (CFSTs) and Concrete Filled Double Skinned Tubes (CFDSTs) for bridge engineering applications. Specimens of both sections are analyzed using the finite element package LS-DYNA under similar seismic and blast loading. First, behavior of CFSTs recorded in s...

Effect of the Concrete Strength on the Concrete-Steel Bond in Concrete Filled Steel Tubes

In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...

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...

Cyclic 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...
