[摘要]傾斜框架結(jié)構(gòu)是一種特殊的復(fù)雜體型建筑結(jié)構(gòu),與垂直建筑結(jié)構(gòu)相比,需要抵御由于傾斜產(chǎn)生的重力傾覆力矩,這種重力傾斜力矩往往比其所處環(huán)境的風(fēng)荷載、地震作用產(chǎn)生的水平傾覆力矩要大得多。建立單跨框架、雙跨框架、帶支撐的雙跨框架的研究模型,得到在不同的傾斜角度下的結(jié)構(gòu)受力、變形特征。[關(guān)鍵詞]傾斜結(jié)構(gòu);受力特性;變形特性中圖分類號:TU375-4文獻標(biāo)識碼:A文章編號:1002-848X(2012)06-0042-05Stress and deformation characteristics of the inclined frame structurePeng Shuili, Zhou Ding, Yang Hanlun(Guangzhou Design Institute, Guangzhou 510620, China)Abstract: The inclined frame structure is a type of special complex building structure. Compared with the vertical structure, it needs to defend against the overturning moment generated by the force of gravity, and this overturning moment is often much greater than the horizontal overturning moment generated by the wind force and earthquake. The stress and deformation characteristics of the inclined frame structure in different inclined angles were analyzed through the single span frame, double span frame and double span frame with diagonal bracing model.Keywords: inclined frame structure; stress characteristics; deformation characteristics作者簡介:彭水力,高級工程師,一級注冊結(jié)構(gòu)工程師,注冊土木工程師(巖土),Email:pengshuili@gzdi.com.參考文獻[1]GB 50011—2010 建筑抗震設(shè)計規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2010.[2]JGJ 3—2010 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京:中國建筑工業(yè)出版社,2011.[3]彭水力,周定,卓瑜,等.廣州新圖書館結(jié)構(gòu)設(shè)計中若干關(guān)鍵問題[J].建筑結(jié)構(gòu),2009,39(11):16-19.
