各有关单位：压型钢板拱形屋盖结构自国外引进以来，在我国推广应用很快。但近年的试验研究表明，这种结构对荷载和制作缺陷比较敏感，一旦处理不当，很容易发生事故。为了确保安全，由我协会建筑钢结构委员会组织有关单位编制了《压型钢板拱形屋盖结构应用暂行规定》，现予公? All relevant units: Since the arched roof structure of profiled steel plate has been introduced from abroad, it has been widely used in our country. However, experimental studies in recent years have shown that this structure is sensitive to loads and manufacturing defects. Once improperly handled, it is prone to accidents. In order to ensure safety, the “Interim Provisions on the Application of Pressed Steel Plate Arched Roof Structures” has been prepared by the Association’s Construction Steel Structure Committee and is now publicly available.
