ABSTRACT To date, our built environment is broadly developed and maintained on the basis of structural design standards. Most design standards contain simplified semi-probabilistic safety concepts that help daily structural engineering decision making using simple calculus. For few projects, the semi-probabilistic safety concept is replaced by advanced probabilistic methods that allow for reliability-based design. Neither include explicit consideration of optimality criteria. However, for the development and the calibration of the semi-probabilistic and probabilistic safety concepts it is important that societal preferences in regard to risk acceptance and the optimal use of natural resources are explicitly considered. In the present contribution, the development and calibration of semi-probabilistic and probabilistic structural design standards is represented as a formal decision problem allowing an optimal combination of reliability elements to be identified.

基于风险的决策制定和结构设计规范的校准——前景和挑战

摘要迄今为止，我们的建筑环境是在结构设计标准的基础上广泛开发和维护的。大多数设计标准都包含简化的半概率安全概念，有助于使用简单的微积分进行日常结构工程决策。对于少数项目，半概率安全概念被允许基于可靠性设计的先进概率方法所取代。两者都不包括对最优性标准的明确考虑。然而，对于半概率和概率安全概念的开发和校准，重要的是要明确考虑在风险接受和自然资源优化利用方面的社会偏好。在目前的贡献中，
