摘　　要：本文建立了基于结构状态方程和偏心结构体系的层剪力-扭矩等效屈服EYST面概念的求解平扭耦联非线性地震反应的分离-予估-修正递推算法,编制了相应的计算程序。通过与三个单层偏心结构模型的破坏性地震模拟试验结果的对比,验证了小变形阶段平-扭耦联地震反应算法的实用性和可靠性。算例表明,该程序数据处理量小,运算快捷,便于应用。Based on the state space formula and the concept of the equivalent yielded base shear-torque surface of asymmetric building structures, this paper developed a kind of simplified partition-prediction-verification approach for evaluation of the seismic nonlinear lateral-torsional coupling effects. The corresponding computer program was also developed and verified by using the experimental result of earthquake simulation test for three asymmetric single story building models. Case study demonstrated that this program is very effective because the data to be processed is usually much less than other nonlinear programs. .
