摘要

摘要: 为了发展基于性能的设计理论，从结构性能概念、性能方法、性能设计的基本要求出发，构建结构全寿命性能设计的性能体系模型。将荷载作用等级通过不同设计使用年限的荷载取值标准来体现，并给出可变荷载取值标准的确定方法。将结构的性能水平划分为三个方面，并将结构的耐久性划分为三个等级，提出了采用三级性能指标(标准)作为结构性能的控制指标(标准)。建议耐久性等级为一、二、三级时，风险性能标准分别取1.0、1.5、2.0；提出采用有害介质扩散深度、钢筋锈蚀率及锈胀裂缝宽度指标作为结构耐久性设计的控制指标。

Abstract: In order to develop the design theory based on performance, from structure performance concept, performance approach, the basic requirement of performance design, the performance system model of structural whole life-cycle performance design was set up.In this paper load action levels were reflected through load value criteria of different design service life, and the determination method of variable load value criteria was given;The performance levels of structure were divided into three aspects, and the durability of structure was divided into three levels.It was proposed that three level performance indexes(criteria) are taken as control indexes(criteria)of structure performance.It was suggested that while durability levels are one, two and three levels, the risk-based performance indexes should be 1.0, 1.5 and 2.0 respectively.It was proposed that the harmful medium diffusion depth, steel rust corrosion rate and rust expansion crack width index are taken as the control indexes of structural durability design.
