In this article we would like to present the effects of those factors on the current state of selected churches, namely on the bearing capacity of their walls.
Validation of the Laboratory Compressive Strength Results by the Schmidt Hammer The resistance of the structure depends on two factors.
The material properties of the structural components of the church’s walls were estimated.

The goal was to evaluate the effect of CSR toughening on processability, mechanical properties and impact strength as well as the interaction with inorganic color particles in the submicron range on the GFRP.
They are advantageous in production and offer a widely adjustable variability of chemical and mechanical properties by the variation of e.g. the chemical precursor, the hardener, the initiator or the accelerator.
For further enhancing critical material properties nano-sized fillers can be used.
Thereby the interphase properties become dominant and can significantly change the material properties, also due to interactions between macromolecules and particles [7].

This friction variation is caused by the complicated factors that affect friction coefficient in the crude oil lubricating medium.
In addition, the effect of such factors as medium corrosion and swelling on rubber friction and wear should be considered in the experiment [2, 3].
Crude oil is also corrosive and makes the mechanical properties of the rubber’s surface decrease and more susceptible to plough, thus increasing the wear. 2.2.
Effect of Load on Friction Properties of NBR Figure 3 shows the curve of NBR/steel pair’s friction coefficient at constant temperature and constant speed.
Temperature on friction properties of NBR The effect of temperature on the elastic hydrodynamic lubrication friction is clearly seen[6].

It is effective in investigating the effects of multiple factors on performance to determine which factor has more influence [4].
Oktem [7] identified the significant factors affecting surface roughness by using analysis of variance (ANOVA) and the optimal cutting combination was determined by seeking the best surface roughness when end milling aluminum. 
Its chemical composition and mechanical properties were listed in Table 1 and Table 2, respectively.
Results indicate that three factors influencing the surface roughness show the following order as: cutting speed, feed per tooth and axis depth of cut.
The main effects of the three factors on the surface roughness are given in Fig. 4.

And the factors were also analyzed, such as wood species, veneer thickness and LVL density.
LVL is a structural material laminated with multiple thick veneers parallel the grain, and exploits a broad space for its development in the area of structural materials for its good mechanical properties.
There are many factors impacting on the ultimate strength of LVL, such as wood species, the thickness of veneer, the density of veneer , mechanical properties of veneer, the type of adhesive, glue spread, hot press process and the thickness of products, etc [2].
Different factors have different levels of effect on the ultimate strength.
This paper only had reliability analysis of the affect the thickness of the veneer on LVL, the reliability level of LVL affected by other influencing factors remain further study.

The mechanical and physical properties of the basic material are given in Table 2.
Levels of variation of input factors.

The largest part of the samples, was broken in the heat-affected zone - HAZ, due to the presence of residual stress, which weakened the mechanical characteristics of the material.

A correlation between the three parameters and the stress-strain properties was specified.
Controllable rheological properties make the MR fluids useful for vibration mitigation devices application.
The estimated factors relationship with the response in this study is given by the following equation.

Conclusion Three parameters for the stress-strain properties were investigated.

However, during long-term use, its appearance may be affected by varying degrees of color change, affecting the appearance and longevity of the dentures.
The color of denture base resins can be affected by many factors, including water absorption, dissolution of material components, pigment accumulation, intrinsic pigments and surface roughness [2-5].
The coloring of restorative materials is the result of both intrinsic and extrinsic factors. 
Extrinsic factors are mainly the attachment and adsorption of the colorant. 
Water is a plasticizer, and adsorbed water reduces the mechanical properties of the material, including hardness, tensile strength and flexural strength.

At the same time, the recycled concrete on the center tube has a "hoop" function, can compensate for the deviation of mechanical properties of recycled aggregate concrete.
The characteristics of steel tube filled with recycled concrete The mechanical properties of recycled concrete compared with ordinary concrete fell and variability increased mostly are used for non-structural system of road.
Hou Rui[4] has studied the constant high temperature steel mechanical properties of recycled concrete columns of the shaft , test design 40 different temperature, different sizes of aggregate replacement ratio, different cross sections specimens, and analysis of the constant high temperature steel recycled concrete axial compressive failure mode, the interaction between the section and working mechanism the stress distribution and the core concrete and the steel tube with ABAQUS, studied the factors influencing coefficient of compressive strength and elastic modulus of the influence factors, and put forward the constant high temperature steel simplified recycled concrete axial compression bearing capacity and modulus of elasticity formula.
Steel tube concrete member having good ductility and the later bearing capacity, good mechanical properties, is a kind of structure form which is more promising.

The main Parameters affecting the Structure The FB100 foamed asphalt testing machine which was jointly developed by Chang'an University and Xi'an Road Construction Machinery Co., Ltd was used in this test.
Considering two factors of the expansion rate and the half-life, the foaming conditions would be chose as follows: atmospheric pressure 300kpa, water pressure 400kpa, asphalt temperate 160℃, foaming water 2%[11].
