(天津大學(xué)建筑工程學(xué)院 天津 300072)[提要] 以足尺模型試驗為基礎(chǔ),根據(jù)經(jīng)典力學(xué)的方法分析了金屬拱形波紋屋蓋的受力性能和主要特點,以及決定該結(jié)構(gòu)承載能力的主要兇素。按照正交各向異性薄板理論對該結(jié)構(gòu)的計算模型進(jìn)行了合理的簡化,給出了該結(jié)構(gòu)承載能力的計算公式,并根據(jù)足尺模型試驗數(shù)據(jù)對計算公式進(jìn)行了修正。

The calculating modcl of the structure is simplificd on the basis of the thcory of orthotropic thin platc, and the formulas of the structural bcaring ca-pacity arc infcrcd,which arc rcviscd according to the data of the full-sizcd modcl cxpcrimcnts.
