摘要: 掉層建筑因不等高基礎(chǔ)嵌固的存在,結(jié)構(gòu)剛度在水平及豎向分布不均勻。 同時,受到邊坡巖土性質(zhì)、邊坡高度、邊坡支擋形式和結(jié)構(gòu)接地類型等因素的影響,掉層結(jié)構(gòu)的受力與變形特點(diǎn)、動力響應(yīng)特征等與常規(guī)建筑結(jié)構(gòu)存在較大差異。 以某山地掉層剪力墻結(jié)構(gòu)為例,從設(shè)計理論依據(jù)、荷載取值、結(jié)構(gòu)布置、抗震驗算、抗震構(gòu)造、邊坡支擋、基礎(chǔ)與主體設(shè)計等方面對掉層結(jié)構(gòu)的設(shè)計方法進(jìn)行了簡要介紹。 通過對掉層結(jié)構(gòu)不規(guī)則性特點(diǎn)和震害特征分析,對其設(shè)計要點(diǎn)進(jìn)行了總結(jié),可為類似項目提供一定的借鑒。

Abstract: Because of the building foundation with different elevations, the structural stiffness is unevenly distributedhorizontally and vertically. At the same time, because of the influence of rock and soil properties, slope height, slopesupporting form and structure earthing type, there are great differences between the building supported by foundations withdifferent elevations and the conventional building in the characteristics of stress and deformation, dynamic response and soon. Take the shear wall structure on the slope as an example, the design method of structure supported by foundations withdifferent elevations was briefly introduced from the aspects of design theory, load value, structure arrangement, aseismicchecking calculation, aseismic structure, slope support, foundation and main body design. Based on the analysis of theirregular characteristics and seismic damage characteristics of the structure supported by foundations with differentelevations, the key points of its design were summarized, which can be used for reference for similar projects.

Keywords:building on the slope; structure supported by foundation with different elevation; seismic performance; retaining wall with anchor; structure design
