Diagrid system is known for its efficient structural behavior besides its outstanding aesthetic characteristics and architectural flexibility. However, a brief existing study on the nonlinear performance of the diagrid system has reported an inefficient nonlinear behavior. Diagrid with fused‐shear link is a newly introduced system that can solve this flaw in the conventional diagrids and keep the advantages as well. In this paper, this newly introduced system is called eccentric diagrid system (EDS). Benefits of the EDS are presented, and a series of nonlinear pushover and time history analyses are conducted to compare EDS with the conventional diagrid system (CDS). In this manner, three different configurations for both EDS and CDS with diagrid angles of 45°, 63.4°, and 71.6° are chosen for two different 12‐ and 18‐story buildings. The models are designed based on an R‐factor equal to 3.6 and 5 for CDS and EDS frames, respectively. Then, the assumed R‐factor for EDS is verified according to Federal Emergency Management Agency P695, and the priority of members yielding is spotted. The results show that EDS can effectively enhance the post‐yield performance and seismic characteristics of the structure relative to CDS, including ductility and overstrength ratio more than 2.5 and 1.3 times, respectively.

偏心和常规斜交系统的抗震性能比较

Diagrid系统除了具有出色的美学特征和建筑灵活性外，还以其高效的结构性能而著称。但是，关于斜交系统非线性性能的现有简要研究报告了一种无效的非线性行为。带融合剪切链接的Diagrid是一种新引入的系统，可以解决传统斜面网中的这一缺陷并保持其优势。在本文中，这个新引入的系统称为偏心斜交系统（EDS）。提出了EDS的好处，并进行了一系列的非线性推覆和时程分析，以将EDS与常规斜交系统（CDS）进行比较。通过这种方式，为两个不同的12层和18层建筑物选择了斜角分别为45°，63.4°和71.6°的三种EDS和CDS配置。这些模型是根据分别等于CDS和EDS帧的3.6和5的R因子设计的。然后，假设REDS的因子已根据美国联邦紧急事务管理局P695进行了验证，并且发现了产生成员的优先级。结果表明，EDS相对于CDS可以有效地提高结构的屈服后性能和抗震性能，延展性和超强比分别超过2.5倍和1.3倍。
