开洞开缝钢板剪力墙的试验与理论研究
|
摘要
作为一种新型的抗侧力体系,钢板剪力墙以较高的抗侧刚度、极限承载力、良好的延性和耗能性能等诸多优点引起各国学者的极大兴趣,并在高层建筑中得以应用。大量研究主要针对在侧向荷载作用下未开缝非加劲钢板剪力墙和未开缝加劲钢板剪力墙的弹性屈曲性能、抗剪性能等而展开,对于开洞开缝钢板剪力墙的研究还处于初步阶段,本文在国内外对开洞开缝钢板剪力墙的基础上,对开洞开缝钢板剪力墙的抗震性能进行试验和理论上的研究,主要研究内容如下:
(1)对两个相同的高厚比为386,比例为1:3的单层单跨开洞开缝钢板剪力墙进行了低周反复荷载作用下的试验研究,分析了钢板墙的滞回曲线、骨架曲线、延性和耗能性能等指标。试验结果表明,开洞开缝钢板剪力墙具有较高的侧向刚度、良好的位移延性性能和耗能能力。
(2)利用有限元软件ANSYS,完全采用壳单元模型对试验进行有限元模拟,计算结果与试验结果吻合良好,为后续的分析研究做了必要的准备。
(3)用有限元方法分析了开洞开缝钢板剪力墙在循环荷载下的抗震性能,主要考虑了内填板高厚比、缝间板条高宽比和内填板边加劲肋刚度等因素的影响。主要研究内容为:荷载-位移滞回曲线和耗能性能,得到一些实用的结论,为开洞开缝钢板剪力墙的抗震设计提供了参考。
As a new kind of lateral resisting element in medium and high-rise building, steel plate shear wall(SPSW)has exhibited many desirable characteristics, such as high initial stiffness, high load-carrying capacity, good ductility and excellent energy absorption capacity. Lots of work has been done to investigate the post-buckling and elastic buckling behavior of unstiffened thin steel plate shear walls and stiffened steel plate shear walls. The study on steel shear wall with slits and holes is initial stage. Based on the previous research work done on steel shear wall with slits, the hysteretic behavior of steel shear wall with slits and holes has been studied theoretically and experimentally in this paper. Main research contents are listed as follows:
Two one-story single-bay steel shear walls with slits and holes of roughly one-third of full scale with panel slenderness ratio of 386 were tested under low cyclic lateral load in order to investigate the hysteresis loops, skeleton curve, ductility and energy dissipation characteristics etc. The steel shear walls with slits and holes showed high lateral stiffness, excellent displacement ductility and energy dissipation characteristics.
A nonlinear finite element model for steel shear wall with slits and holes was developed using the as-built dimensions in order to simulate the test. The effective and validity of the model were demonstrated by comparing its cyclic load condition with experimental results. The finite element analysis of the specimens provided a sound foundation for further research of this kind of steel shear wall.
The hysteretic behavior of steel shear wall with slits and holes under low cyclic load has been studied using the finite element method. It was influenced by many factors, such as panel slenderness ratio, aspect ratio of panel between slits and stiffness of side stiffener to panel etc. The research of hysteresis loops and energy dissipation characteristic showed that steel shear wall with slits and holes was an excellent lateral resisting element.
