摘要:
为了从试验角度研究混凝土随机性对结构反应的影响,以4片相同的4层1:3比例缩尺模型的短肢剪力墙结构为研究对象,进行了拟静力试验研究,得到了荷载-位移曲线、混凝土和钢筋的应变曲线及墙体局部相对位移曲线。从水平承载力、侧向刚度、位移延性3个方面对比分析了各片墙体的反应,并对4片墙体的实测数据进行了统计分析,给出了不同顶点位移下的3个典型横截面受力状态的变化过程,最后研究了各试件在破坏特征上的差异性。研究结果表明:混凝土材料随机性的本质特征,使得混凝土结构在非线性发展阶段具有明显的损伤随机演化特性,因此,混凝土非线性与随机性的耦合效应对结构反应所造成的影响不可忽视。
Abstract:
In order to investigate how randomness of concrete had effects on structural responses by means of experiments, authors carried out a pseudo static experiment on the same four-story 1:3 scaled model of short-leg shear wall structure. Load and displacement curves, strain curves of reinforced concrete and partial relative displacement curves were obtained. Moreover, the horizontal bearing capacity, lateral stiffness, as well as displacement and ductility were discussed, and measured data of four walls were analyzed, then, redistributed processes of inner forces behaviors were given in three typical cross-sections under different vertex displacements. Finally, the failure characteristics of different specimens were contrasted. The results show that the structural nonlinear damage stochastic evolution is formed due to concrete material stochastic characteristic. So coupling effect of concrete non-linearity and randomness has notable influence on structural responses.
