The use of two frequencies gave reasonable results to solve the equation system for the axial load S for both materials, see Fig.4.
The difference in length for the two materials is related to the fact that different grips with different surface properties had to be used.

Introduction In the engineering construction,sand is the common material in construction which has been used in great amount, not only directly applied in buildings such as roadbeds, bridges and culverts, tunnels and buildings but used in masonry of structure[1].
In Table 4,is ultimate moment, based on material’s observed strength and calculated by the normal formula in code;is flexural ultimate moment of the test.

While involving the aspect of type in construct high or super high building, bundled tube structure obtained the good application in high and super high building due to the bundled tube structure's superiority in load transferring, earthquake-resistance, flexural rigidity and it could exert material characteristic properly, and it also could provide much larger available space, making the layout more flexible, as well as much higher[3,4].
umerical example and analysis of calculating results Example: the cross section of bundled tube structure for material of reinforced concrete is shown as Fig.3. the average thickness of equivalent thin-wall tube is 0.45m, the height is 12m and the altitude of the tube is 180m.
The elastic constants of structural materials to resist pull, push or shearing force are respectively 1 1 2 2 , , , E fE G fG E rE G rG = = = = , the elastic modulus of steel reinforced concrete is 7 2 3.25 10 / , 0.45 E k% m G E = × = .

If the maximum stress in a gear tooth is less than the fatigue limit for the material, the tooth should not fail even after prolonged running.
The von mises stress is also known as the maximum distortion energy criterion, octahedral shear stress theory, which is used to estimate the yield of a ductile material.
