Abstract

A new seismic design methodology has been developed for precast concrete diaphragms. Seismic design factors were used to be applied on top of diaphragm seismic design forces in the current code. These factors, established through extensive parametric studies, align diaphragm design strengths with different seismic performance targets. A simplified evaluation structure with a single-bay plan was used in the parametric studies. This simplified evaluation structure is reasonable and cost-effective as it can comprehensively cover structural geometries and design parameters. However, further verification and investigation are required to apply these design factors to prototype structures with realistic layouts. This paper presents diaphragm design of several precast concrete office buildings using the new design methodology. The applicability of the design factor to the office building was evaluated and verified through nonlinear time history analyses. The seismic behavior and performance of the diaphragm were investigated for the precast concrete office buildings. It was found that the design factor established for the new design methodology is applicable to the realistic precast concrete office buildings.
预制混凝土办公楼隔震设计因素的验证
一种新的抗震设计方法已经发展为预制混凝土隔板。现行规范将抗震设计因子应用于隔震设计力之上。这些因素是通过广泛的参数研究确定的,使隔膜设计强度与不同的抗震性能目标保持一致。在参数研究中,采用了一种简化的单舱计划评价结构。这种简化的评价结构能够全面涵盖结构几何形状和设计参数,是合理的、经济的。然而,将这些设计因素应用于具有现实布局的原型结构还需要进一步的验证和研究。本文介绍了采用新设计方法对几幢预制混凝土办公楼进行隔膜设计。通过非线性时程分析,对设计因子在办公楼中的适用性进行了评价和验证。对预制混凝土办公楼的抗震性能进行了研究。结果表明,新设计方法所建立的设计因子适用于实际的预制混凝土办公楼。

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.
