Description

Technical Field

[0001] The invention relates to the technical field of metal roof performance evaluation, and in particular to a corrosion-resistant corrugated steel plate metal roof performance evaluation system. Background Art

[0002] At present, metal roofs are widely used in buildings, industrial plants, warehouses and other fields due to their durability, light weight and low maintenance cost. However, as the use time increases, metal roofs may be affected by various environmental factors, such as corrosion, aging, deformation, etc., resulting in the degradation of many types of performance. In order to ensure the long-term stable operation of metal roofs, regular performance evaluation is essential. Through performance evaluation, problems with metal roofs can be discovered in time and corresponding maintenance measures can be taken to extend their service life.

[0003] However, the existing corrosion-resistant corrugated steel sheet metal roof performance evaluation system only collects monitoring index data of the metal roof in different distribution areas of the metal roof, including longitudinal plastic strain value, transverse plastic deformation value, fatigue damage value and historical failure rate, to achieve comprehensive evaluation of the metal roof in different regions. It does not consider the accurate quantification of the performance of other performance items of the metal roof except the structural performance items at the current moment, and does not quantify the overall performance of the metal roof at the current moment, and cannot accurately evaluate the current performance status of the metal roof. For example, the patent with the publication number "CN115062979A" and the name "Metal Roof Performance Evaluation Method and System Based on Hierarchical Analysis and Fuzzy Evaluation" includes the following steps: collecting monitoring index data of metal roofs in different distribution areas of metal roofs, including longitudinal plastic strain value, transverse plastic deformation value, fatigue damage value and historical failure rate; taking the location factor of the distribution area where the metal roof is located as the regional layer index, taking the monitoring index data of the metal roof as the criterion layer factor, and determining the index weight affecting the status evaluation of the metal roof based on the hierarchical analysis method; determining the metal roof performance evaluation level based on the fuzzy comprehensive evaluation method. This patent integrates the information of the area where the metal roof is located and the information of the data collected by the monitoring system to achieve a comprehensive evaluation of the metal roof in different regions. However, this patent only realizes the comprehensive evaluation of the metal roof in different distribution areas of the metal roof by collecting monitoring index data of the metal roof, including longitudinal plastic strain value, transverse plastic deformation value, fatigue damage value and historical failure rate. It only considers the structural performance items of the metal roof at the current moment to realize the comprehensive evaluation of the metal roof in different regions. It does not accurately quantify the performance of other performance items of the metal roof except the structural performance items at the current moment, nor does it quantify the overall performance of the metal roof at the current moment, and it is impossible to accurately evaluate the current performance status of the metal roof.

[0004] Therefore, the present invention proposes a corrosion-resistant corrugated steel sheet metal roof performance evaluation system. Summary of the invention
