(中國建筑設(shè)計(jì)研究院，北京100044)[摘要] 金臺夕照博物館“金臺”部分結(jié)構(gòu)單元為斜框架鋼結(jié)構(gòu)，平面、立面布置均不規(guī)則。豎向構(gòu)件均與地面傾斜，平面布置為“凹”字形，凹入尺寸占結(jié)構(gòu)總尺寸的80%。為增強(qiáng)結(jié)構(gòu)整體性、改善使用性能，在其頂部增加較大剛度連系梁。另外，對該結(jié)構(gòu)使用ETABS、SAP2000、SATWE多種程序按照多種形式對該結(jié)構(gòu)進(jìn)行了模擬復(fù)核驗(yàn)算，并詳細(xì)比較、分析了各種程序和各個(gè)模型的計(jì)算結(jié)果，綜合分析、確定設(shè)計(jì)依據(jù)。

( China Architecture Design & Research Group, Beijing 100044, China)Abstract: The Jintai part of the structure of Jintaixizhao Museum is diagonal steel frame. The plain and vertical layouts are irregular with the inclined vertical frame members. The plain layout is concave shape. The indentation size occupies 80% of the total size. Stiffness link beam has been increased at the top of the structure to enhance the structural integrity and improve the use of performance. In addition, a variety of procedures such as ETABS, SAP2000, SATWE are used to analogue, check the safety of the structure. The results of the calculations are applied to detailed comparison and analysis to determine the design basis.
Keywords: diagonal steel frame; irregular steel structure
