[摘要] 古建筑在長(zhǎng)期的自然條件作用下結(jié)構(gòu)材料性能一般都發(fā)生了惡化，有些甚至使用功能也發(fā)生改變，必然影響它們的受力性能，需對(duì)其安全性能進(jìn)行分析評(píng)估?？紤]到古建筑是文物，不能采用傳統(tǒng)的破損或半破損評(píng)估方法的特性，給出了一種無(wú)損綜合評(píng)估法用于解決這類(lèi)問(wèn)題，并以故宮午門(mén)城臺(tái)為例，詳細(xì)介紹了這種無(wú)損檢測(cè)方法的過(guò)程，并對(duì)午門(mén)進(jìn)行了結(jié)構(gòu)安全性能評(píng)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
