Safety assessment of existing glass curtain walls
What is it about?
The occurrence of safety incidents for existing glass curtain walls pronounced menace to the security of both lives and property. Undertaking safety assessment for existing glass curtain walls carries essential practical significance. This paper proposes a novel approach to the safety assessment of existing glass curtain walls.
Why is it important?
This research establishes a framework of evaluation indicators for existing glass curtain walls and divides the safety ranks of each indicator into four tiers: Safe, Mild risk, Moderate risk, and High risk. Quantitative and qualitative indicators are quantified via the variable fuzzy cloud algorithm and cloud model. The information cloud combination weighting method is introduced to determine the weight clouds of indicators. Finally, a two-dimensional assessment result is derived using an improved fuzzy comprehensive evaluation method and fuzzy entropy.
