【摘要】 本文在三层预应力横缝摩擦剪力墙木模型试验与研究的基础上,通过单层钢筋混凝土结构模型的试验,进一步验证了这类结构的优越性和工作机理。它以预应力为拼装手段,在结构的梁底与墙顶间形成摩擦水平缝,通过摩擦缝在强烈地震作用下的往复滑动达到耗能减震的目的。 文中阐述了四(?)品结构模型试验的结果。在试验的基础上,推导了反映摩擦缝滑动机制的结构内力与变形的计算方法,计算结果与试验结果相符合。更多还原

【Abstract】 This paper presents an experimental research of a new type shear wall mechanism. The precast shear wall panels are installed by means of vertical prestressing so that slidable horizontal friction joints are to be formed between the top of the panel and the bottom of the beam.Tests of four single-storeyed R/C models of such structure under cyclic reversed lateral loading have been conducted to demonstrate the above mentioned principles. The results observed indicate that the slide of the friction joints is normal, and that the critical damping and the energy dissipated are quite large.a calculation method reflecting the sliding mechanism of the friction joints is developed basing on the measured results of tested models and gives satisfactory results that agree well with those observed during the tests.更多还原
