［摘要］主要研究了單邊支承弧形懸挑結(jié)構(gòu)在豎向荷載作用下的受力性能。通過(guò)對(duì)基本模型的研究發(fā)現(xiàn)，該結(jié)構(gòu)在豎向荷載作用下成立的機(jī)理主要是通過(guò)環(huán)梁彎曲來(lái)抵抗整個(gè)結(jié)構(gòu)的傾覆；影響其結(jié)構(gòu)受力性能的因素主要有環(huán)梁的彎曲剛度和弧形支承數(shù)目及其對(duì)應(yīng)圓心角的大小。

［關(guān)鍵詞］弧形支承；懸挑結(jié)構(gòu)；彎曲剛度；受力性能

Abstract: 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.

Keywords: supported by single arc side; cantilever structure; flexural rigidity; mechanical behavior
