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
