Abstract: In recent years, cold formed steel sections are used more and more as primary framing components as well as secondary structural systems. The geometry can significantly influence the stability response of cold formed steel members. This reportis an investigation concerning the structural behavior of the cold formed steel beams and their failure modes. The beam profile is cold formed steel section and experimental procedure on cold formed steel section is conducted. Thin sheet steel products are extensively used in building industry, and range from purlins to roof sheeting and floor decking. Generally, these are available for use as basic building elements for assembly at site or as prefabricated frames or panels. These thin steel sections are cold-formed, i.e. their manufacturing process involves forming steel sections in a cold state (i.e. without application of heat) from steel sheets of uniform thickness. Sometimes they are also called Light Gauge Steel Sections or Cold Rolled Steel Sections. The thickness of steel sheet used in cold formed section construction was 3.1 mm. The method of manufacturing is important as it differentiates these products from hot rolled steel sections. Normally, the yield strength of steel sheets used in cold-formed sections is at least 280 N/mm2, although there is a trend to use steels of higher strengths, and sometimes as low as 230 N/mm2.

Abstract: The smart grid is the future development direction of the power industry. The ultimate goal of the smart grid should be to build a real-time monitoring system covering the entire production process of the power system, including power generation, transmission, power transmission, power distribution, and power scheduling. A smart grid is the development trend of the future power industry, and the application analysis of the smart grid is the basis for ensuring economic and safe operation. Smart Grid Application Analysis (SGAA) based on big data, is of considerable significance to the development of the power system. Based on the comprehensive comparison of domestic and foreign literature, this paper puts forward the prediction application of "Big Data +" and makes a simple evaluation of the possible potential power-side load and regulator prediction model of new energy development. It also introduces the shortcomings in the current stage, as well as the critical technologies of the big data industry that need to be developed urgently. The smart grid is the future direction of power industry development, but the current stage of the development of related technology is not enough, this paper gives suggestions for the development of smart grid and big data.
