摘　　要：依据宋代《营造法式》,设计了4种试验用宋式木构足尺及比例模型并确定了相应的屋盖形式;因屋面瓦和铺衬在雨雪天吸水而使屋盖重量加大,提出了考虑使用期和施工期不同工况计算屋盖重量;分析了《营造法式》中黄松与华北落叶松的关系,引入应县木塔柱轴力并与实际计算的屋盖重量对比,初步推定了《营造法式》中各材等间按照确定的相似准则在荷载效应上存在对应关系。结果可为计算宋式类似木构屋盖重量提供借鉴,为进一步探索材份制中的相似关系和木结构模型相似系数提供参考。Combined with ＂ Ying Zao Fa Shi＂,the size of the four type of song dynasty wooden components and related contents in the design of the roof are introduced.On the basis of the facts that the weight of roof became heavier because of rain and snow,a method of calculating the weight of the roof was proposed under different cases considering construction and using period.The simplified method of working condition combined with the calculation results was put forward.The relationship between yellow pine and larchen had been clear.There was a corresponding relationship in the load effect between the various modular.The results would provide reference for calculating similar wooden roof weight,and further exploring the similarity relation in CaiFen system and model tests.
