Abstract EN
A new posttensioned T-stub connection (PTTC) for earthquake resistant steel moment resisting frames (MRFs) is introduced.
The proposed connection consists of high strength posttensioned (PT) strands and bolted T-stubs.
The post-tensioning strands run through the column and are anchored against the flange of the exterior column.
The T-stubs, providing energy dissipation, are bolted to the flange of beam and column and no field welding is required.
The strands compress the T-stub against the column flange to develop the resisting moment to service loads and to provide a restoring force that returns the structure to its initial position following an earthquake.
An analytical model based on fiber elements is developed in OpenSees to model PTTCs.
The analytical model can predict the expected behavior of the new proposed connection under cyclic loading.
PTTC provides similar characteristic behavior of the posttensioned connections.
Both theoretical behavior and design methods are proposed, and the design methods are verified based on parametric studies and comparison to analytical results.
The parametric studies prove the desired self-centering behavior of PTTC and show that this connection can reduce or eliminate the plastic rotation by its self-centering behavior as well as providing required strength and stiffness under large earthquake rotations.
