Experiment on aluminum alloy members under axial compression

Xiaonong GUO,Shuiping LIANG,Zuyan SHEN

Frontiers of Structural and Civil Engineering 2015, Volume 9, Issue 1,   Pages 48-64 doi: 10.1007/s11709-014-0271-9

Abstract: To improve the design methods of Chinese aluminum alloy members, experiment of 63 profiled aluminum alloy members, made of Chinese aluminum alloy 6061-T6, under axial compression is conducted in this paper. Valuable experimental data are obtained. At the same time, in order to obtain the relevant data, a large number of other experimental data from published papers and technical reports are collected and sorted out. 167 valid experimental data points are obtained finally. Furthermore, for the purpose of creating column curves, the aluminum alloy members under the axial compression, used in experiments, are analyzed by means of FEM. Based on the numerical results, 2 column curves are created by means of the numerical fitting method. The column curves are compared with the calculated data according to the experimental results for verification, and also are verified with the curves in design codes of several relevant countries. The numerical results show that the column curves obtained in this paper are valid and reliable.

Solvates and polymorphs of clindamycin phosphate: Structural, thermal stability and moisture stability

Junbo Gong, Dejiang Zhang, Yuanyuan Ran, Keke Zhang, Shichao Du

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 2,   Pages 220-230 doi: 10.1007/s11705-017-1624-4

Abstract: Clindamycin phosphate (CP), an antibacterial agent, has been reported to form several solid-state forms. The crystal structures of two CP solvates, a dimethyl sulfoxide (DMSO) solvate and a methanol/water solvate (solvate V), have been determined by single crystal X-ray diffraction. The properties and transformations of these forms were characterized by powder X-ray diffraction, Single-crystal X-ray diffraction, differential scanning calorimetry, thermo gravimetric analysis, hot-stage microscopy, and dynamic vapor sorption. Very different hydrogen bonding networks exist among the host-host and host-solvent molecules in the two crystal structures, resulting in different moisture stabilities. The thermal stabilities of the two solvates upon heating and desolvation were also studied. When the temperature was above the boiling point of methanol, solvate V converted to a polymorphic phase after a one step desolvation process, whereas the desolvation temperature of the DMSO solvate was below the boiling point of DMSO. At the relative humidity above 43%, the DMSO solvate transformed to a hydrate at 25 °C. In contrast, solvate V did not transform at any of the humidities studied.

Zhou Junliang

Strategic Study of CAE 2010, Volume 12, Issue 3,   Pages 4-14

Abstract:

To make a study on the anti-sliding stablity of foundation of hydraulic structures on subbed soils, and based on the result by anti-sliding tests of dragged concreting clip plates in foundation pits, the anti-sliding stablity of foundation on subbed soils was determind. There are 3 different forms of largest displacement with 8 different forms of silding move of subbed soils caused by the different maximum compressive stresses of eccentric loads on them. It is worked out a design method to determine the sliding frictional resistances and the forms of sliding moves of foundation subbed soils; a formula for the integal frication resistance to sliding for the structure;a formula for the the anti-sliding move of subbed soils and a rule to distinguish the plane sliding move of foundation subsoils with others. To analyze 3 structures which have been established provides a confirmation with the reality for the design method.
