葛道福 (鐵道部第十一工程局勘測(cè)設(shè)計(jì)院)劉士清 (湖北省建筑科學(xué)研究設(shè)計(jì)院 武漢 430071)[提要] 采用無(wú)窮級(jí)數(shù)解析法推導(dǎo)了沿直線邊簡(jiǎn)支、沿圓弧邊簡(jiǎn)支或固支的各種扇形板的位移和內(nèi)力計(jì)算公式,并給出了幾種不同頂角的扇形板在均布面荷載和均布線荷載作用下位移和彎矩的實(shí)用計(jì)算表格,可供設(shè)計(jì)時(shí)查表選用,亦可供其它接近扇形板的異形板作近似計(jì)算用。
[關(guān)鍵詞] 扇形板 位移 內(nèi)力 計(jì)算 解析法The displacement and internal force formula of various angle sectorial plates, simply supported on the linear edge and simply or fixed supported on the arc edge, is derived by an infinite series theoretical method. Based on the formula, the authors give the deflection and bending moment's practical calcula-tive forms of sectorial plates under a uniformly distributed vertical load unit area and unit length.
Keywords: sectorial plate; displacement; internal force; calculation, theoretical method
