摘　　要：主要研究了单边支承弧形悬挑结构在竖向荷载作用下的受力性能。通过对基本模型的研究发现,该结构在竖向荷载作用下成立的机理主要是通过环梁弯曲来抵抗整个结构的倾覆;影响其结构受力性能的因素主要有环梁的弯曲刚度和弧形支承数目及其对应圆心角的大小。The mechanical behavior of cantilever structure supported by single arc side under vertical loads was studied. Through the analysis of basic models, it is found that the structure can resist its overturning by the bending of the ring beam. The bending rigidity, corresponding central angle and support numbers of the ring beam are the main factors which affect the mechanical behaviors of the cantilever structure supported by single arc side.
