The fragility curves are known as an efficient probabilistic-base tool used to evaluate vulnerabilities in various fields. However, accurate access to these curves has always been associated with complexities that have made it difficult for structural designers to achieve. Many attempts have been made to provide a new fragility function using State-based philosophy (SBP) theory to replace the conventional fragility function in recent years. A method in which gradual changes in structural properties due to a destructive factor is generally used to ultimately create a function with a new structure to describe the structure's fragility. In this study, after the usual method of obtaining the fragility curve is briefly reviewed, the new structure proposed for the fragility function by SBP will be explained. A completely new technique will then be introduced using a combination of selected (and not complete) information from the usual incremental dynamic analysis method in the SBP fragility function. The result is a fragility curve with perfectly acceptable accuracy that computational efforts to achieve have been dramatically reduced. This claim's validity is examined by performing this technique on some two-dimensional special moment frames models, and its advantages and disadvantages and accuracy are further explored.

脆弱性曲线是一种有效的基于概率的工具，用于评估各个领域中的漏洞。但是，对这些曲线的精确访问始终与复杂性相关联，这些复杂性使结构设计人员难以实现。近年来，已经进行了许多尝试以基于状态的哲学（SBP）理论提供新的脆弱性功能来代替传统的脆弱性功能。通常使用一种方法，在该方法中，由于破坏性因素而导致的结构特性逐渐变化，最终用来创建具有新结构的函数来描述结构的脆弱性。在这项研究中，简要回顾了获得脆性曲线的常用方法之后，将解释由SBP为脆性函数提出的新结构。然后，将使用SBP脆弱性函数中通常的增量动态分析方法中选择的（而不是完整的）信息的组合来引入一种全新的技术。结果是具有完全可接受的精度的脆弱性曲线，从而大大减少了要实现的计算量。通过在某些二维特殊矩框架模型上执行此技术来检验此主张的有效性，并进一步探讨其优缺点和准确性。
