摘要
通过对三个严格按照中国宋·《营造法式》中有关大木作的形制与构造要求制作的木构架模型在水平反复荷载作用下的试验研究 ,分析与探讨了中国古代木造结构在相应状态下的变形及受力特征及其榫卯节点工作机制 ,通过对榫卯节点的转动弯矩与相应转角试验数据的分析与研究 ,确定了榫卯节点的转动刚度 ,提出了该类型结构在水平地震荷载作用下的计算模型 ,并就额枋正截面上的最大应变与内力 ,作了理论计算与试验数据的对比 ,两者吻合较好 ,从而证明了所选模型的合理性 。
Through an experimental study on three wooden frame models, that are made in accordance with the requirements for the shape and structure by 《Ying Zao Fa Shi》 (Building Standards) of the Song Dynasty (960-1270.A.D), the deformational behavior and the mortise tenon joint mechanisms of such frame in the corresponding state has been put to analysis.As a result of the study on the rotational moment and the displacement of six mortise-tenon joints,the rotation rigidity of these mortise-tenonts has been defined, bringing forward the calculat model for this type of wooden structure under horizontal seismic action. By means of comparison, the agreement of theoretical calculation with the test results has been proved with reference to the maximum strain on the normal section of e fang(beam). The rationality and effectiveness of the model suggested provides a useful reference for the study of the characteristics of ancient Chinese buildings under horizontal seismic action.
