摘要

地震分析被认为是高层建筑设计的一个重要方面,特别是在地震易发地区。结构体系的选择对建筑物的地震反应有相当大的影响。本研究的目的是比较沙特阿拉伯麦地那地区多层建筑中使用的多板系统的地震性能。本研究的目标是确定在地震带中最有效和最高效的楼板系统性能。在这项工作中使用了ETABS V20.3程序来模拟和评估三种不同类型的板系统的地震反应:平板,实心和空心块板类型。许多地震方面,包括楼层位移,基底剪力,楼层漂移,柱力和弯矩,估计每个系统。研究对各个体系的地震反应进行了检验和评估,并给出了结论并进行了讨论。研究结果表明,楼板体系的选择对建筑物的地震反应有相当大的影响。空心砌块体系的基础剪力值和弯矩最小,而平板体系的基础剪力值和弯矩最大。实心板体系的数值处于中间。在层位移和柱力方面,研究还表明空心砌块型体系在层漂移方面表现有效,而实心板体系则优于其他体系。研究结果可以通过提供重要的见解和建议,帮助设计师和工程师确定地震易发地区多层建筑的最佳楼板系统。

A Comparative Study of the Seismic Response of Different Concrete Slab Systems for a Multistory Building in Madinah
Seismic analysis is considered as an important aspect of the design of high-rise buildings, particularly in earthquake prone areas. The structural system choice can have a considerable impact on the building seismic response. The goal of this study is to compare the seismic behavior of multiple slab systems used in a multi-story building in Saudi Arabia's Madinah region. This study's goal is to determine the most effective and efficient slab system performance in a seismic zone. The ETABS V20.3 program was used in this work to model and assess the seismic response of three different types of slab systems: flat, solid, and hollow blocks slab types. Many earthquake aspects, including story displacement, base shear, story drifts, column forces, and bending moments, are estimated for each system. The study examines and assesses each system's seismic response, and the conclusions are given and discussed. According to the findings, the choice of slab system has a considerable impact on the seismic reaction of the building. The hollow block system has the least base shear value and bending moments, while the flat slab system has the greatest. The values in the solid slab system are in the middle. In terms of story displacement and column forces, the study additionally indicates that the hollow block type system performs effectively in terms of story drifts, however, the solid slab system outperforms the others. The study's findings can assist designers and engineers to determine the best slab system for multistory buildings in seismic-prone areas by providing important insight and suggestions.

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.
