摘要
为揭示ＭＩＣ－１２０彩板波纹拱壳结构的破坏机理，对其进行现场足尺寸试验。通过对８组不同跨度、不同板厚的彩板拱壳进行分级加载，观测其极限承载能力、变形特点以及破坏形式。试验结果表明：影响彩板拱壳极限承载能力的关键是跨度，拱壳的主要破坏形式是腹板局部受压失稳。
An experimental investigation is presented for the arc-shell roof structure with thin-walled corrugated steel section, and a technical evaluation to MIC-120 section in its span range, failure form and deformation behavior is given. The test carried out includes totally 8 full size specimens, which were loaded to collapse under half or full span uniformly distributed loads. It is found that local instability of web of this type of structure is a main reason to cause failure, and that its span should be limited in application.
