| 摘 要： | 根据结构力学的知识对我国古建筑檐椽进行了结构分析,将古建筑檐椽简化为一次超静定连续梁,用力法作出结构的弯矩图,然后令弯矩图中正负弯矩的最大值相等,即求出古建筑檐椽的合理出挑尺寸x=14a,这与《清式营造则例》中对古建筑檐椽合理出挑尺寸的规定是一致的。

| Abstract: | According to the knowledge of structural mechanics,ancient building eave-rafter in our country is structurally analyzed.Ancient building eave-rafter is simplified as a statically indeterminate continuous beam,and bending moment diagram of the structure is drawn via force method.Then the maximums of positive and negative bending moment equalize in the bending moment diagram,and the reasonable overhanging length of ancient building eave-rafter,namely x=14a,is obtained,which is consistent with building eave-ra... |
