Parametric study of hexagonal castellated beams in post-tensioned self-centering steel connections

Hassan ABEDI SARVESTANI

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 5,   Pages 1020-1035 doi: 10.1007/s11709-019-0534-6

Abstract: The effects of important parameters (beam reinforcing plates, initial post-tensioning, and material propertiesof steel angles) on the behavior of hexagonal castellated beams in post-tensioned self-centering (PTSCThe web-post buckling in hexagonal castellated beams has been identified as the dominant failure modewhen excessive initial post-tensioning force is applied to reach greater bending moment resistance,so it is required to limit the highest initial post-tensioning force to prevent this failure.

Seismic tests of post-tensioned self-centering building frames with column and slab restraints

Chung-Che CHOU, Jun-Hen CHEN

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 323-334 doi: 10.1007/s11709-011-0119-5

Abstract: Post-tensioned (PT) self-centering moment frames have been developed as an alternative to typical moment-resistingWhen a PT frame deforms laterally, gaps between the beams and columns open.The method is verified by cyclic tests of a full-scale, two-bay by one-story PT frame.Moreover, a sliding slab is proposed to minimize restraints on the expansion of the PT frame.only minor differences in peak drifts caused by expansion of the PT frame.

Efficacy and safety of JAK inhibitor INC424 in patients with primary and post-polycythemia vera or post-essential

Xin Du,Daobin Zhou

Frontiers of Medicine 2016, Volume 10, Issue 4,   Pages 437-443 doi: 10.1007/s11684-016-0472-9

Abstract:

A phase II study (A2202) was performed to evaluate the efficacy and safety of JAK inhibitor ruxolitinib in 63 Chinese MF patients. Ruxolitinib was given twice a day (bid) at a starting dose of 15 mg (n=25) or 20 mg (n=38) based on a baseline platelet count. About 94.7% of the patients achieved a reduction in spleen size, 27.0% of which exhibited significant reduction (≥35%) at week 24. Significant improvement in debilitating constitutional symptoms, as assessed by MFSAF v2.0, was observed in patients treated with ruxolitinib. Ruxolitinib treatment was generally well tolerated by Chinese patients. Although the treatment was associated with an increase in certain adverse events (AEs) that were established as identified risks (anemia and thrombocytopenia), these AEs were considered manageable in this clinical setting. Ruxolitinib provided substantial reductions in splenomegaly and improvements in symptoms, and was well-tolerated by Chinese patients with MF.
