【提要】 高層建筑結(jié)構(gòu)隨著層數(shù)的增多，變形和內(nèi)力都不斷累加，設(shè)計中應(yīng)該考慮施工過程的影響。以高層結(jié)構(gòu)的施工順序為基礎(chǔ)，將結(jié)構(gòu)分為若干個子結(jié)構(gòu)，計算結(jié)構(gòu)的累計內(nèi)力和變形來考慮結(jié)構(gòu)的施工過程，并編制了相應(yīng)的計算程序。算例計算結(jié)果表明，建議的方法能夠精確地模擬施工過程對結(jié)構(gòu)變形和內(nèi)力的影響，而采用其他方法計算時，內(nèi)力應(yīng)該乘以相應(yīng)的放大系數(shù)。

Abstract:The deformation and internal force increase with the layers adding of the tall building.The effect of the construction process should be considered in design.Based on construction process of high rise building, the structure is divided into several substructures,and the cumulative internal force and deformation are adopted to simulate the construction process.The calculation program is edited.The results of the example show that the suggested method can accurately simulate the effect of the construction process on the structure.The internal force should be magnified when the other calculation method is adopted.
