Analysis on Dynamic Response of Building Structure
in Blasting Vibration

Faculty of Land Resource Engineering, Kunming University of Science and Technology, Kunming, P.R.
The single vibration parameter standard does not take full consideration of the characteristics of the blasting vibration spectra, the dynamic feature of buildings and the strength of the building materials, thus there exists great discrepancy between the practical work and the theory.
After getting the shearing force, we can compare it with the shearing resistance index of the building materials, thus get the conclusion that to what extent the blasting vibration load effects the building structure[5]~[7].

Introduction
Aluminum is a promising anode material with negative potential, high electrochemical equivalent, wide variety of sources, and low cost [1].
These factors restrict its application as a sacrificial anode material [2-6].
With the constant increasing demand of property of sacrificial anode material in various work environments, it’s, particularly, essential to explore new high-performance sacrificial anode materials and study the influence of alloy elements on their properties.

Mg(OH)2 is also an environmentally friendly and safe material.
It is notable that no combustion by heating in air occurs, indicating that the Mg chips are converted to safe material, Mg(OH)2, which is also environmentally friendly.

Abstract.
Introduction Metalworking fluids (MWFs) are complex mixtures of chemicals and are indispensable materials in industry.
Material and Methods Ozone was produced from air using a OZONFILT® OZVa type 2 ozone generator (Prominent), which is capable of producing up to 15 g/hour of O3.

The material of microelectrode is shot of and the splash metal scraps
are formed, which are high temperature.
The material is become the condensate in a short time, and the hard martensite is formed at the surface of the microelectrode.
The great parameter can be selected at early stage and a large quantity material can be etched by one pulses discharge.

But the mixture of anti-seepage curtain is alkaline materials, the alkaline comes from the Ca(OH)2 generated by cement hydration reaction.
Because of acid corrosion for building materials, acid-fast cement and acid admixture are used to prevent the concrete curtain damaged by acid corrosion.
