Furthermore, the micro/nanofibrils isolated from natural fibers have much higher mechanical properties as reported by Sakurada et al. [5] that the cellulose crystal regions are a bundle of stretched cellulose chain molecules with Young`s modulus of 150 GPa and strength in the order of 10 GPa.
The conditions of freeze drier (Virtis Genesis 12 EL) were -20 ºC to + 20 ºC over 4 days in 5 ºC increments.

Four acceleration waves (El-Centro, Taft, Qianan and Beijing Hotel) are used as seismic excitations, representing the shear waves vertically propagating from the rock base.

The real CFST columns tested by Han et al. [16] were used in this paper, and the parameters were as follows: column height was 1.5m, width and depth of square section were 120mm, the thickness of steel tube were selected as 2.65mm, 3.65mm and 4.65mm, respectively, fcu’ was 61.2MPa, was 0.2, the yield strength and elastic modulus of steel tube were 340MPa and 207GPa.
The El Centro earthquake and harmonic excitation were selected and scaled to the peak acceleration of 1.5g and 0.1g respectively.

This effect can be justified by the equation suggested by Ghomashchi et al. [5]: Increasing pressure (P) causes an increase in the freezing point (Tf) of the alloy.

PL measurements are very useful because they allow showing the energy levels due to defects in the ZnO matrix, as already reported by Behera et al [14].

Hence Wang et al. have ever proposed an OFS based on multiple total internal reflections in heterodyne interferometry [12].

Experimental results have shown that diagonally reinforced coupling beams are capable of maintaining their shear strength with good stiffness recovery and energy dissipation under large displacement(Paulay and Binney 1974; Shiu et al.1978; Tassios, Moretti, and Bezas 1996; Galano and Vignoli2000).
