A shake table test on such structural system has been performed by Zhao et al. [1] that indicate the dynamic characteristics are complex and the torsional mode has become the first mode of the structure.
Four earthquake records, El Centro, Kobe, Wenchuan Wolong and SHW2 artificial earthquake wave, are chosen as the shake table input accelerations.

However, the poor elevated temperature properties restrict the widely use of Al-containing alloys, owing to the existence of Mg17Al12 phase, as well as Mg7Zn3 in Mg-Zn alloy.
Recently, Jan Bohlen[5] et al. has reported that Zn can modify the rolling texture of ZK10, ZE10, ZEK100, ZKE410 and ZW41.
Tang et. al [15] has reported MgZn phase is existed when 4 wt.% Zn is added in Mg-5Sn alloy, thus the Zn content (1～3 wt.%) in this paper is relative low for forming Zn-containing phases.
Compared with Mg-5Sn sheet, the UTS, YS and EL of Mg-5Sn-3Zn sheet in ED increased about 50MPa, 30MPa and 14%, respectively.
The UTS, YS and EL of all four kinds of alloys increase with Zn added.

E-beam deposition of a Ti/Al alloy was followed by rapid thermal processing annealing at 1000oC for 5 min in nitrogen in order to fabricate Ohmic contacts with a thickness of 100 nm to the pregion.
In Fig. 2(a) we present schematically the evolution of a rhombic stacking fault observed in our experiment, following the model of Skowronski et al. [6] for the formation of a rhombic SF.
Contrary to EBIC results, EL investigations of dislocation loops have previously shown that the Si- and C-core partials have different luminescence intensities.
As mentioned above, EL is sensitive only to radiative recombination whereas the intensity of EBIC contrast depends on the rate of both radiative and nonradiative recombination.
This provides a possible explanation for dissimilarly visualized Si- and C-core partials by EBIC and EL.

Similarly, the application of cryo-rolling to the commercial Al alloys is anticipated to refine their grains to the submicrometer level, i.e.
Fig. 1 shows the microstructures and mechanical properties of the cryo-rolled and annealed 5052 Al alloys.
From the above, it is obvious that large total elongation above annealing temperature of 250℃ can be attributed to the increased amount of equiaxed and/or coarsened grains. 100 150 200 250 300 350 400 450 Annealing Temperature, C TS (cold) YS (cold) % El (cold) TS (cryo) YS (cryo) % El (cryo) Strength, MPa 0 50 100 150 200 250 300 350 0 5 10 15 20 25 Elongation to Failure, % Thermal analysis.

Introduction In recent years, some researches had been performed on inclined CFST stub columns, such as Han et al. [1] and Han et al. [2].
The longitudinal and transverse steel fibers are in compression and tension, respectively, and the longitudinal strains (el) and the transverse strains (et) are denoted as positive and negative, respectively.

Fig. 6 shows Electroluminescence (EL) images captured from the backside for previously body diode stressed SiC MOSFETs during body diode forward bias with ISD=1 A and VGS=-4.5 V.
EL patterns can be seen in parts of the chip area where lead frame and solder was removed by mechanical polishing.
No specific features were seen in EL for samples with zero RDSon drift.
