摘要

钢筋混凝土框架体系中的填充墙是非结构细节的重要贡献之一。通常填充墙现在通常不承担任何载荷,在设计中不要忘记它是钢筋混凝土框架系统的一部分。本研究的主要目的是了解具有填充壁的rc体之间的相互作用。在本试验研究中,三个试件可以在随后的方法基础上进行1 / 10比例尺的制作,即无填充的钢筋混凝土框架形式、沿砖砌体加筋的钢筋混凝土框架形式、阻尼条件下加筋的钢筋混凝土框架结构。在1 / 8比例的框架系统模型上进行了一系列实验。本文讨论了框架在静荷载作用下的强度、延性和破坏机理。试验结果表明,加筋框架的最终承载能力比不加筋框架高1.472倍。斜支撑体的初始刚度为1.0。比无填充的框架高5倍。加筋框架的延性比未加筋框架的延性提高1.137倍。加筋砖砌筑框架的初刚度大于无砖砌筑框架的初刚度。有补强带的体的延性比无补强带的体的延性高1.137倍。将破坏试样与配筋带进行对比,可避免理节理破坏引起的突落现象。对角支撑增加了节点的强度,减少了节点的对角开裂破坏。

Strengthening of Infilled Wall with RC Framed Structure Under Provision of Single Equivalent Diagonal Strut Action
Infilled wall in R.C framed systems one of the essential contribution of non-structural detail. Normally infilled wall usually does now not take any load and it isn't don't forget in design a part of R.C framed systems. The essential purpose of this study to perceive the interaction amongst R.C.Body with infilled wall. In this experimental study, three specimens may be prepared one-10th scale version below the subsequent methodologies, R.C.Framed form without infill, R.C.Framed shape with reinforcement along the brick masonry, R.C.Framed structure with reinforcing band under damper conditions. A series of experiments have been performed on one-8th-scale model of the framed systems. This look at discusses the aspect of strength, ductility and failure mechanism of the frame under static loading. The test stop result shows that the final load carrying functionality of R.C.Frame with reinforcement band is 1.472 instances more than that of R.C.Frame with out infill. The preliminary stiffness of the body with diagonal strut is 1.0.Five times higher than that of the frame with out infill. The ductility of frame with reinforcement band is 1.137 instances extra than that of frame without infill. The preliminary stiffness of the frame with reinforced brick masonry is greater than that of frame with out brick masonry. The ductility of body with reinforcement band is 1.137 instances greater than that of body with out infill. Comparing the failure sample with reinforcement band is avoid the surprising falling due to bedding joint failure. The diagonal strut beautify the strength at joints and it reduces the diagonal cracking failure.
