Abstract.
Introduction SiC is an attractive material for microelectromechanical systems (MEMS) intended for operation in harsh environments [1].
The spread in the Young's modulus data is likely due to variations Journal Title and Volume Number (to be inserted by the publisher) 3 in beam dimensions within a particular device as a result of lateral variations in the lithographic patterning and SiC etching steps.
These measurements demonstrate the favorable properties of poly-SiC as a desirable MEMS material.

In analysis, elastic-perfectly plastic model was thought for Q345 steel material.Vertical displacement was load on the top of upper steel frame when the bottom of lower steel frame was restrained.
Fig.7 Plastic strain distribution of specimen on condition 2 Fig.8 Plastic strain distribution of specimen on condition 3 Fig.9 Comparison of Force-displacement curves of specimen on condition 1~3 Fig.10 Elastic stiffness of specimen on condition 1 and Hook model in Sap2000 Parameters of calculation model in Sap2000 program identify The new type of anti-tension device has a very important feature, it will not offer any restrains to the upper structure above the isolation story, which can move freely in the horizontal direction or downward in the vertical direction, in the Sap2000 FEM program, the characteristic of the nonlinear link element named as Hook meets well with the new device in this paper, but the shortcoming of Hook is that material nonlinearity can’t be considered.

Also, an increase in decrepit houses and lack of construction site will require more demolition work, which will produce more demolition wastes (DW), and construction materials made of demolition wastes will increase in the future.
