[摘要] 古建筑在长期的自然条件作用下结构材料性能一般都发生了恶化，有些甚至使用功能也发生改变，必然影响它们的受力性能，需对其安全性能进行分析评估。考虑到古建筑是文物，不能采用传统的破损或半破损评估方法的特性，给出了一种无损综合评估法用于解决这类问题，并以故宫午门城台为例，详细介绍了这种无损检测方法的过程，并对午门进行了结构安全性能评估。

Abstract: Ancient building's structural performances have already deteriorated because of the long-term effect from natural environments, and even some buildings have also changed their service conditions. Hence, ancient building load bearing properties must be influenced and it is necessary to evaluate their safety properties. Considering that most of the ancient buildings belong to cultural relics, conventional evaluation methods, such as crash test or semi-crash test are not suitable for them In this paper, a nondestructive comprehensive evaluation method is given to solve this problem And the platform of the Meridian Gate in the Forbidden City is evaluated using this method.
Keywords: ancient building; nondestructive comprehensive evaluation method; safety property; constitutive relation, calculation and analysis
