The influence of long term annealing on microstructure of Al-Cu4-Ni2-Mg aluminium alloy was investigated.
Introduction Al-Cu alloys are less frequently used than Al-Si-Cu grades due to technological problems in production process (e.g. high propensity to microcracking during casting).
There are some suggestions that decomposition of supersaturated a(Al) solid solution in other precipitation hardened alloys like Al-Cu-Mg, Al-Si-Cu, Al-Mg-Si follows the same route as in the Al-Cu alloys with some specific features of the particular stages of the process [4].
Based upon the EDS results the phases forming large size particles was identified as Al-Cu-Ni, Al-Cu-Ni-Fe and Al-Cu-Mn [3,5].

The results was consistent with that of Gao et al.[8] While Kim et al. [6] reported that the mung bean starch of 5 different Korean cultivars displayed CA-type crystalline structure, which is a mixed pattern of A- and B-type crystals.
Zhao et al [10] studied effect of heat treatment on the crystalline structure of the starch, which had some changes with the increase of temperature.
Gao et al [22] studied the effect of sucrose on pasting temperature, who found that with increase of addition, pasting temperature increased slightly.

El-Nemr et al [8] attempted to use different design codes such as ACI 440.1R-15, CAN/CSA S806-12, CAN/CSA S6-14, and Eurocode 2 to determine the cracking moment of GFRP RC beams with different reinforcement ratios.

When temperature change with DT, thermal strain increment e caused by thermal mismatch strain is (3) Thermal mismatch strains of interphase and lamellae are expressed as ep and el , (4) Average strain tensor of composite can be described by Eshelby theory (5) Where Wp=Cp (I-M) and =Cl(I-M) represent intrinsic stiffness tensor of interphase and lamellae, M is Eshelby tensor, Cp and Cl represent stiffness tensor of interphase and lamellae.
Mechanical property parameters of matrix Al2O3 are: Young’s modulus E0=402Gpa, Poisson’s ratios u0=0.233, and thermal expansion coefficient a0=8.3×10-6/℃, for lamellae ZrO2, corresponding parameters follow as: El=233Gpa, ul=0.31, al=10.6×10-6/℃.

The seismic wave used is a longitudinal input El Centro wave, whose peak acceleration is changed to be 0.6g.
Calculation results of the seismic dynamic response In ABAQUS, seismic response analysis under the excitation of El Centro wave is carried out on the three-span continuous girder bridge with and without semi-active control devices.
