This paper tests the influences of the machine vibration on the workshop structure by using the vibration testing method,and analyzes on the vibration regularity and reasons of the structure floor based on the testing result,which provides the reliable scientific foundation for the safety evaluation on the floor structure.

This article breached traditional disposal way about workshop extension crack and handled design methods of "resisting " and "setting free" to deal with extension crack in unite workshop structure in the Tyre Factory on the South-West of China , it gained favourable effect and took some references to its next developing .

Study on the self-vibration characteristics of powerhouse structure of the Three Gorges Hydropower Station;

In case of high tailwater pressure, in order to meet the requirements of integral stability and stress in design of powerhouse structure, the some issues shall be considered, such as: joints between powerhouse and dam, structure types of machine hall and auxiliary plant, structure types of retaining works.

A method is introduced for the calculation of the intensity of the welding column of steel structure workshop and cantilever shoulder nodal point.

From the heat preservation heat insulation,the fire protection,the temperature expands and contracts,the room covers the support,the structure anticorrosion,set up the surface design and so on several aspects to make the discussion to the steel structure workshop design,causes the steel structure workshop tends the security,the economy,artistic.

Combining with the destruction situation of the power plant in Wenchuan large earthquake,the author analyzes causes of the main workshop structure seismic destruction,provides attention problems in the main workshop structure anti-seismic design,so as to establish multi-line defense of the main workshop anti-seismic,ensure people\'s life and property safety.
