[摘要] 金台夕照博物馆“金台”部分结构单元为斜框架钢结构，平面、立面布置均不规则。竖向构件均与地面倾斜，平面布置为“凹”字形，凹入尺寸占结构总尺寸的80%。为增强结构整体性、改善使用性能，在其顶部增加较大刚度连系梁。另外，对该结构使用ETABS、SAP2000、SATWE多种程序按照多种形式对该结构进行了模拟复核验算，并详细比较、分析了各种程序和各个模型的计算结果，综合分析、确定设计依据。

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
