［摘要］采用SAP2000軟件模擬一棟600m高的超高層鋼-混凝土混合結(jié)構(gòu)，考慮了三種不同的豎向施工標(biāo)高找平方式，分別是逐層找平、三層找平一次、六層找平一次，得到了不同施工找平方式下結(jié)構(gòu)的豎向變形、豎向變形差及水平構(gòu)件內(nèi)力隨時(shí)間的變化規(guī)律。對(duì)比不同施工找平方式之間的關(guān)系并給出其影響規(guī)律，基于逐層施工找平過程進(jìn)行理論推導(dǎo)，得出每層豎向構(gòu)件預(yù)留長(zhǎng)度的計(jì)算公式，計(jì)算出各層的預(yù)留長(zhǎng)度，使計(jì)算期時(shí)得到的結(jié)構(gòu)實(shí)際層高與設(shè)計(jì)層高一致，此種豎向構(gòu)件預(yù)留長(zhǎng)度的算法對(duì)超高層建筑的現(xiàn)場(chǎng)施工具有參考價(jià)值。

Abstract:A 600m high super high-rise steel reinforced concrete structure was simulated by  using  SAP2000 software to research the effect of three construction leveling methods, including level finding storey-by-storey, level finding every three storeys and level finding every six storeys. Vertical deformation, vertical deformation difference and the variation of internal force of horizontal members with time were obtained under different construction leveling methods. By comparing the relationship of different leveling methods, the law of leveling method′s impact was found. Formula to calculate the vertical member reserved length of each storey was derived based on the level finding storey-by-storey, so that the actual floor levels are the same with the design levels during the caculation period. The results provide a reference in construction of super high-rise buildings.

Keywords:construction simulation; storey leveling method; reserved length; super high-rise building
