There are many factors affecting the bond strength between the lightweight concrete and reinforcing steel, where the compressive strength plays an important role in bond strength, and the bond strength is increased by increasing the compressive strength.
With regard to mechanical properties, with the exception of bonding with concrete epoxy coating, steel rods can be constructed in the same way as carbon steel, since steel is the only bearing component of the product.

Experiment research on mechanical behavior for latticed concrete-filled steel tubular tower with three limbs Bin Li1,a, Zhongzhou Han1,b and Chunyan Gao1,2,c 1 Aerding Avenue 7, The Inner Mongolia University of science & technology, Baotou, 014010, China 2 Yudao Avenue 29, Nanjing University of Aeronautics and Astronautics, Nanjing, 210016, China abtlibin@189.cn, bhanzhongzhou23@163.com, cgao-197844@163.com Keywords: Latticed, Wind turbine tower, Concrete-filled steel tube, Mechanical behavior Abstract.
The stress mechanism and failure process, hysteretic properties, bearing capacity and energy dissipation capacity were studied by quasi-static test on the tower model.
In our country the earthquake action is frequent, with the increment of the wind turbine capacity on tower top, the quality on the tower top are more and more larger and the inertial force of the tower also increase correspondingly, In high earthquake-intensity areas the seismic load has already become an important factor that can not be ignored in the tower design [1-2].
From the mechanical point of view, cone cylindrical tower is a spatial thin shell, which has the advantages such as simple and beautiful shape, clear force transfer system, easy maintenance; But with the large-scale development of wind turbine, its bottom diameter will more and more be affected by local transportation conditions (such as bridge height limit).
(3) The latticed CFST tower with three limbs has excellent seismic behavior and mechanical performance, and there is the value to further research and popularization.

With the improvement of science and technology in China, and the application of modern professional, factory, mechanical and information means provides sufficient science and technology basis for the transformer design level.
Therefore, in order to make single judgment of every resonance transformer property, there must first of all be transformation processing, followed by the sequential blending of every resonance transformer property judgment.
In multi-resonance transformer information blending system, the set of resonance transformer is factor set.

This characteristic is generated for abaca fibre properties.
The improvement of mechanical properties of fibres can be achieved by treatment and coupling agents and in this study, impact modifier and coupling agent (maelic anhydride (MAH)) are used in composites and the statistical analysis of hardness property at various composite compositions were carried out.
Standard specimens with load 17.5 kg were prepared for the determination of Brinell hardness number (BHN) properties.
The responses of three factors are to be determined and these three factors are designated as Χ₁ (abaca fibre), Χ₂ (maelic anhydride (MAH)) and Χ₃ (impact modifier (IM)), respectively as shown in Table 3.
The ANOVA analysis indicates a linear relationship between the main effects of abaca fibre wt% maleic anhydride wt%, and impact modifier wt%, and the quadratic relationships with factors of abaca fibre wt%, maelic anhydride wt%, and impact modifier wt% and interaction between the three factors.

Perhaps, numerical analysis performed by FEM could give the answers referent of all these issues concerning the CCM, because applying a numerical evaluation will not introduce external factors that can affect the recalled strain data needed to perform it.
The mechanical properties established as input data are: E = 210 GPa, σy = 420 MPa and υ = 0.29.
It is considered that, FEM could be the best option for the evaluation of the CCM, because there are not external factors that can affect the recalled strain data needed to perform it.

We found that the resulted nanocomposites exhibit high conductivity and strong ferromagnetic properties.
Co-Fe3O4; [Co-Fe3O4]:[EDOT]=1:0.95 (B); 1:1.9 (C); 1:3.8 (D); 1:7.6 (E) Electromagnetic Properties.
It is found that the electrical and magnetic properties of the Co-Fe3O4/PEDOT-PSS nanocomposites are strongly affected by the [Co-Fe3O4]:[EDOT] ratios.
The macroscopic conductivity relies on some external factors such as compactness, defects and density that relates to the physical property of the sample.
Whereas, the microscopic conductivity of the material is associated with the doping level, conjugation length and chain length etc. factors that is determined by the polymerization conditions.

The wide application of these materials depends on their mechanical properties, which are typically studied by uniaxial compression tests, likewise the thermomechanical behavior of these materials has always been a very important issue and has been studied for some years.
Muhammad R. studied the mechanical behavior of concrete after exposing it to high temperatures from 100°C to 1000°C, to later carry out different simulations, where they concluded that sodium silicate and curing time are the most important factors. influencers that affect the strength and residual compression of the mortar.

Insights about a microscopic-level structure are particularly necessary because it is thought that a strong and complex correlation exists between mechanical properties and the molecular structure of a polymer.
Such knowledge can provide a general guideline to design new structural polymers of excellent mechanical properties.
There are several important factors which are expected to strongly affect the mechanical properties, e.g., temperature and molar mass.
However, these factors have not been investigated in the previous study.

The grain-size dependence on deformation mechanism was found to affect yielding behavior both microscopically and macroscopically which can influence various mechanical properties such as fatigue and creep.
In order to improve the latter two properties, deformation mechanism should be better understood and controlled.
%Zn (AZ31) alloys were used for mechanical testing and microstructure observation.
The horizontal axis is a ratio of Schmid factor of the corresponding nonbasal slip systems to that of the basal slip systems.
In the case of single crystal CRSS data [2-5], nonbasal slip becomes active when the Schimid factor ratio (the S ratio) is more than 100.
