摘要

本研究旨在通过钢筋混凝土结构中各种重要参数(即开口在填充墙中的百分比，一楼的几根柱子被移除部分填充)来研究填充框架对逐渐倒塌情景的影响。为此，利用ABAQUS软件建立三维有限元模型。将数值和实验结果进行对比，证实了有限元模型能够准确模拟al - chaar等人(2002)的实验模型行为。结果表明，实验结果与数值结果吻合较好。此外，结果表明，对抗渐溃性有显著影响，且不可忽视;除柱区域的竖向位移减小率可达80%。

Effects of Non-Structural Walls on Mitigating the Risk of Progressive Collapse of RC Structures

This study aims to investigate the effect of the infilled frames through various important parameters (i.e., the openings’ percentage in infill walls several columns on the first floor are removed partial infilled) in the RC structures, subject to progressive collapse scenarios. To this end, 3D finite element models were constructed by using the software ABAQUS. Numerical and experimental results were compared to substantiate the finite element models’ capability of simulating the experimental models’ behavior of Al-Chaar et al. (2002) in an accurate manner. The results showed that there was good agreement between experimental and numerical results. Moreover, the results indicated that there was a significant effect, which cannot be neglected, on the progressive collapse resistance; the reduction ratios in vertical displacement at the regions removed columns can reach up to 80%.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
