本程序用于对国内十一个城市进行的薄壁型钢腐蚀速度实测值进行回归计算,得出腐蚀规律曲线和腐蚀速度的预报值。六十年代,薄壁型钢(以下简称“薄钢”)结构在我国曾有较大的发展。根据薄钢规范管理组一九八二年十月对全国的调查,自一九七五年以来,薄钢又以压型板、墙梁、网架、屋架、刚架、檩条和钢柱等多种形式在我国获得新的发展。据统计目前我国采用薄钢的规模
This program is used to calculate the actual corrosion rate of thin-walled steel in eleven cities in China. The predicted values of corrosion curve and corrosion rate are obtained. In the 1960s, the structure of thin-walled section steel (hereinafter referred to as “thin steel”) has been greatly developed in our country. According to a survey conducted by the Thin Steel Standardization Management Group in October 1982 in the whole country, since the introduction of thin steel plates in the form of pressure plates, wall beams, grids, roof trusses, rigid frames, purlins and steel columns since 1975 Various forms have gained new development in our country. According to statistics, China’s current use of thin steel size
