A Calculating Model of Reliability of Resistance Considering Fuzzy and Grey Factors for Existing Structures

摘要

From the basic concept of the grey system theory, this paper points out that there are gery property factors in the resistance of existing structures for first time. And presents the concept fo grey reliability. In the paper, a synthetical calculating model of reliability for existing structures considering fuzzy and grey factors is proposed based on author's former paper. And showed the type of grey resistance white weighting function and fuzzy resistance failure subject function. Lastly, the paper affords the reliability calculating formula of earthquke-resistance considering grey factors on existing seismic structures.
