Past earthquakes had shown vulnerability of infill walls especially under out of plane (OOP) loading. Although some new infill walls show a good OOP performance, generally, they do not have the right economic justification or have complexity in construction. Therefore, in this paper, an innovative economical infill wall is presented that is not complicated in construction. The proposed wall constructed by light expanded clay aggregate in especial shape that reinforced with side plates, top, and bottom rebars. Experimental and numerical studies were carried out to investigate its seismic performance. Experimental results showed a high continuity between blocks of wall due to its especial shape that is increased ultimate OOP strength and ultimate OOP displacement of the wall. Numerical results indicated, because the infill wall is isolated from boundary frame, no drift is imposed to infill wall from boundary frame. Therefore, the infill wall only suffered OOP seismic acceleration. Due to light weight of the infill wall, low OOP load that corresponds to seismic acceleration is applied to the infill wall. In the infill wall, no separation is made even up to drift frame of 2.5%. The relations to design of the proposed infill wall were also presented.

利用轻质膨胀粘土骨料的创新填充墙：一项实验和数值研究

过去的地震显示出填充墙的脆弱性，特别是在平面外（OOP）荷载下。尽管一些新的填充墙显示出良好的OOP性能，但通常来说，它们没有正确的经济依据或结构复杂。因此，在本文中，提出了一种创新的经济的填充墙，其结构并不复杂。拟议中的墙体是由轻质膨胀粘土以特殊形状建造的，并通过侧板，顶部和底部钢筋进行了加固。进行了实验和数值研究以研究其抗震性能。实验结果表明，由于其特殊的形状，墙块之间具有很高的连续性，可以提高墙的极限OOP强度和墙的极限OOP位移。数值结果表明，因为填充墙与边界框架是隔离的，所以不会对填充墙与边界框架施加任何漂移。因此，填充墙仅遭受OOP地震加速度。由于填充墙的重量轻，因此将对应于地震加速度的低OOP负载施加到填充墙。在填充墙中，即使达到2.5％的漂移框，也不会发生分离。还介绍了与拟议的填充墙设计的关系。
