Structure and properties of solid and dynamic load tests measuring 4.1 for large, complex steel structures can be carried out in situ non-destructive inspection Dongguan real Dutch steel works directly test the structural performance. Structure and properties of solid charge according to the provisions of this standard test conducted in Appendix H. Loading coefficients and determine the principles according to the provisions H.2 determination can also be adjusted according to the specific circumstances of the appendix. When the bearing capacity of 4.2 pairs of structures or members of doubt, can be a prototype or full scale model load test. Tests should be entrusted to specialized institutions have sufficient equipment capabilities were. Should develop a detailed test program before the test, including test purpose, the specimen selection or production, loading device, measuring points and test equipment, procedures, and test results of the assessment methods to load. Appendix H test program can be developed, and should be subject to the consent of the parties before the test. 4.3 For large and important new steel structure system, should the actual structural dynamic tests to determine the structure of dynamic parameters such as vibration periods. Dynamic test should comply with the provisions of Appendix E of this standard. 4.4 stress steel rods, the choice of resistance strain gauges or other effective method for testing according to the actual conditions. China Steel Association, after investigation, after listening to expert advice and recommendations relating to the installation of steel manufacturers, the drafting of the "steel industry in the country on the" second five "Reflections and Suggestions draft strategic plan" to seek the views of the persons concerned in After, the association will organize experts concrete implementation, improve, in order to promote the "second five" steel industry to achieve greater development. Steel industry due to its economic and technological superiority, carbon emission reduction, recycling economy and may industrialization, industrial development of the steel structure, better able to adapt and meet the current needs of the national economy, it will become a huge market, Many enterprises, innovation and continuous, full of vigor and vitality of one of the emerging industries. Institute for Information Industry Outlook "2014-2018 China steel structure industry Market Outlook and Investment Planning Analysis Report" analysts believe that the price of steel canopy, "Twelve Five" period, obtain policy support steel industry is expected in the marine engineering, residential areas of the bridge to flex its muscles and achieve doubling production.
