(現(xiàn)代設(shè)計集團華東建筑設(shè)計研究院有限公司,上海200002)[摘要] 大連小平島假日公寓主塔大屋面高度269. Om,屬超限高層結(jié)構(gòu)。主樓平面呈十字形,屬平面不規(guī)則結(jié)構(gòu)。在水平地震作用下,連接部位樓板要承受較大水平剪力。在初步設(shè)計階段采用兩種常用方法對樓板承擔(dān)的剪力進行估算,并且推導(dǎo)出一種剪力估算新方法:位移差法。通過與PMSAP計算結(jié)果對比得出:位移差法計算結(jié)果與PMSAP計算結(jié)果較為接近。位移差法概念清晰、易于操作,在初步設(shè)計階段使用該方法,可以較為準(zhǔn)確的得到樓板的面內(nèi)剪應(yīng)力。

( East China Architectural Design & Research Institute Co. , Ltd. , Xian Dai Architectural Design Group, Shanghai 200002, China)Abstract: The super high-rise holiday apartment in Dalian Xiaoping island is 269 meters height, In addition, the structural plan presents crisscross, and this form belongs to irregular structure. Large horizontal shear stress occurs at the connected position under the horizontal seismic force. Designers adopt two methods to estimate the shear force at the stage of the initial design, as a result, a new method to estimate the shear force is developed and it is called displacement difference method. The comparison between the new method and the PMSAP method is made and the results of two methods is comparable. The concept of the displacement difference method is easy and it can be used in the initial design stage, the accurate results can be derived by this method.
