混凝土结抗震评估和改造构的要求

[中文适用范围]： 本文件规定了混凝土结构抗震评估和改造的要求。 它可用于降低地震事件期间结构倒塌或翻转造成地震损坏的风险。 本文件规定了强震发生前现有钢筋混凝土结构和受震结构的详细抗震评估与判断、抗震改造方案与设计、抗震改造实施的框架和原则。 它是一个伞式文件，其一般性规定旨在为评估现有钢筋混凝土结构的地震损坏/预期损坏和修复/改造的综合原则提供广泛的选择余地。 因此，它应与合理的工程判断结合使用。 本标准适用于按照特定国家或地区规定的结构设计规范设计的钢筋混凝土结构和预应力混凝土结构。 本标准不适用于无筋混凝土和砌体结构。 [外文原描述]： This document provides requirements for seismic assessment and retrofit of concrete structures. It can be used to reduce the risk of seismic damage by structural collapse or turnover during a seismic event. This document provides the framework and principles of methods of detailed seismic assessment and the judgment, seismic retrofit plan and design, seismic retrofit execution of existing reinforced concrete structures before the occurrence of a severe earthquake and of the structures struck by an earthquake. It is an umbrella-type document with general provisions intended to provide wide latitude of choice in terms of comprehensive principle on the evaluation of the seismic damage/expected damage of existing reinforced concrete structures and repair/retrofit. Therefore, it is intended to be used in conjunction with sound engineering judgment. This document is applicable to reinforced concrete structures and pre-stressed concrete structures that have been designed on the basis of the structural design criteria set in a specific country or region. It is not applicable to unreinforced concrete and masonry structures.
