摘 要: 根据相似关系理论设计与制作了一大比例自复位钢筋混凝土框架,并进行模拟地震振动台试验。该模型为单跨两层两榀框架,平面尺寸3.0 m×1.5 m,层高1.5 m,总高3.0 m. 框架柱和短边梁均采用预应力筋提供自复位能力,消能组件分别为橡胶和角钢。主要介绍该结构模型的设计与制作过程,包括模型相似比例的确定、模型简化设计及模型施工等振动台试验的前期工作,并对大比例振动台模型设计中存在的问题进行讨论,所提供的自复位混凝土框架模型设计思路和过程可为今后相关的试验工作提供参考。
关 键 词: 混凝土与钢筋混凝土结构;自复位;振动台模型;钢筋混凝土框架

Abstract: In this paper, based on similar relation theory, a large-scale model was designed and constructed for shaking table test to study the seismic performance of self-centering reinforced concrete frame. A two-story frame of two specimens was designed and constructed with 3.0 m�.5 m dimension, 1.5 m for each layer and 3.0 m in height. The self-centering capacity of columns and short beams were achieved by prestressed tendons respectively, and rubber and angles were used as energy components. The shaking table model design was described in details including model material selection, similitude relationship determination, model simplified design, model construction and other preparation works. Furthermore, the questions in large scale shaking table test model design were discussed. The method applied in model and design of this self-centering frame will be helpful to other relative experimental studies in the future.
Key words: concrete and reinforced concrete structure; self-centering; shaking table test model; reinforced concrete frame
