基于模糊层次法的藏式砌体劣化风险权重系数试验标定研究

藏式砌体广泛应用于藏式建筑墙体中,在自然灾害、人为损坏等赋存环境影响作用下,出现了裂缝、倾斜及材料损伤等多种劣化形式.基于科学手段对劣化藏式墙体的健康状况进行合理评估一直是藏式古建砌体保护的难点.基于模糊评价法和层次分析法,对影响藏式砌体墙的几种主要损伤形式进行综合研究,通过参数分析迭代耦合,得到裂缝、倾斜及材料损伤等...

Experimental calibration of risk weight coefficient of Tibetan masonry based on fuzzy analytic hierarchy method

Tibetan masonry is widely used in Tibetan building walls. Various forms of deterioration such as cracks, tilt and material damage have occurred under the influence of natural disasters, man-made damage and other environmental impacts. A reasonable assessment of the health of deteriorated Tibetan walls by using scientific methods has always been a difficult point for protection of ancient Tibetan masonry structures. This paper conducts a comprehensive study on several main damage forms that affect Tibetan masonry walls relied on the fuzzy evaluation method and the analytic hierarchy process. The weight coefficients of various influencing factors such as cracks, tilt and material damage are obtained through the parameter iterative process and verified by two brick masonry test models. A quantitative evaluation standard for performance of the masonry structure wall is given. It also gives the weight coefficient that objectively determine using fuzzy evaluation method.The research results can be used for the rapid comprehensive evaluation of the damage state of the dual-purpose Tibetan masonry structure, and provide a reference for daily inspection and safety assessment of Tibetan building walls.
