框架侧移的连续化模型分析

提出了用简单连续化模型分析框架侧移的近似方法，根据应变能相等的原则，得出了与原框架等效的连续化模型及其侧移的解析解。实例分析表明，用此种方法分析框架侧移具有较高的精确度，同时，连续化方法能使计算分析得以大大简化，因此，它对分析大型框架，尤其在初步设计阶段具有很高的实用价值。

Analysis of Frame Lateral Displacement Using Continuum Model

An approximate method based on a continuous model is proposed for analysis of strain energy equalization, and a continuum model equivalent to the original frame is derived. By use of this model, a function of frame lateral displacement is established. The analysis of practical examples illustrates that the method for analysing frame lateral displacement is of high accuracy. In the meantime, the continuum method can result in considerable simplicity in computation analysis,making the method attractive in the analysis of large frames,especially during the preliminary design stage.
