建筑结构设计方案的模糊综合评价

Fuzzy Multiple Goals Decision-making Method for Structural Design Scheme

建筑结构设计方案的评价涉及到各种技术经济指标,且指标具有非统一性、随机性和模糊性,评价结果易受各种人为主观因素的影响,造成评价的失真。为了客观而准确地评价建筑结构设计方案,论文结合建筑结构设计的特点,运用模糊综合评价法,提出了一种适合建筑结构设计方案的评价方法,使评价结果更具可靠性,最后用实例验证了该方法的可行性。研究结果表明,应用该方法不仅可以了解和掌握建筑工程设计的整体安全性,而且能够提供预防和改进措施。

The purpose of this paper concerns the more objective and more accurate safety assessment method adapted to design scheme of building structure. Because the involved indexes are inconsistent, random and fuzzy, the evaluation can be affected by various subjective factors that cause anamorphic resulL The safety evaluation technique applied was fuzzy multiple goals decision making method. At the same time, the character of building structure design was considered. The paper included the following main parts ： formation of the index system of assessment on building structure design, detailed assessment project, steps and application example. In summing up it may be stated that this method make not only the holistic security of construction engineering design be controlled but also the precaution and improvement measure be offered.
