【提要】 根據勢能駐值原饋鯨立痢框架頂部側移和桿端轉角之間的關系方程，推導出框架結構在水平節(jié)點荷載作用下的頂部側移計算公式，方法簡便適用，且計算精度較高，為框架結構頂部側移的計算提供了一種新的簡便計算方法，得出了用D值法求得的框架頂部側移一般比實際側移偏大的結論。
【關鍵詞】 框架結構 頂部側勢能住康原理
Simplified Calculating Method of Top Displacement for Frame Structure/Liu Shuzhi1，Jiang Lin2，Yang Zhanfeng3(1 Architecture and Civil Engineering School,UST Inner Mongolia,Baotou 014010,China; 2 Baosteel Real Estate Company,Baotou 014010,China; 3 Baotou Building Management Bureau,Baotou 014010,China)
Abstract:The equation of relationship between the top displacement and the rod angle of frame structure is established according to the principle of stationary potential energy. The formula of the top displacement under horizontal loads is deduced. The method is simple,applicable and accurate. It provides a new and simple calculating method for the top displacement of the frame structure. It is proved that the top displacement of the frame structure calculated by the D value method is a bit larger than the real result.
Keywords:frame structure； top displacement； principle of stationary potential energy
