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 properties of steel angles) on the behavior of hexagonal castellated beams in post-tensioned self-centering (PTSC) connections undergone cyclic loading up to 4% lateral drift have been investigated by finite element (FE) analysis using ABAQUS. The PTSC connection is comprised of bolted top and bottom angles as energy dissipaters and steel strands to provide self-centering capacity. The FE analysis has also been validated against the experimental test. The new formulations derived from analytical method has been proposed to predict bending moment of PTSC connections. The web-post buckling in hexagonal castellated beams has been identified as the dominant failure mode when 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. Furthermore, properties of steel material has been simulated using bilinear elastoplastic modeling with 1.5% strain-hardening which has perfectly matched with the real material of steel angles. It is recommended to avoid using steel angles with high yielding strength since they lead to the yielding of bolt shank. The necessity of reinforcing plates to prevent beam flange from local buckling has been reaffirmed.

Parametric study on the mixed solvent synthesis of ZIF-8 nano- and micro-particles for CO adsorption:A response surface study

Alireza Hadi, Javad Karimi-Sabet, Abolfazl Dastbaz

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 4,   Pages 579-594 doi: 10.1007/s11705-018-1770-3

Abstract: The room temperature synthesis of ZIF-8 micro- and nano-particles was investigated using a mixed methanol-water solvent system. ZIF-8 particles of good quality and high crystallinity were obtained. Response surface methodology was used to determine the effect of the synthesis conditions on the ZIF-8 yield, particle size distribution, and mean particle size. The ligand/metal salt molar ratio followed by the amount of sodium formate (the deprotonating agent) and then the amount of water (i.e., the composition of the mixed solvent) respectively had the largest effects on both the ZIF-8 yield and particle size. Results showed that mixing of solvents with different strengths in producing ZIF-8 crystals is a practical method to size-controlled synthesis of ZIF-8 particles. This method is more favorable for industrial-scale ZIF-8 synthesis than using excess amounts of ligands or chemical additives (like sodium formate). In addition, ZIF-8 samples with different mean particle sizes (100, 500, and 1000 nm) were used for CO adsorption and the mid-sized ZIF-8 particles had the highest adsorption capacity.
