CHOSEN ASPECTS OF DEFINING TECHNICAL WEAR OF BUILDINGS
讨论了界定建筑物及其构件技术磨损边界值的问题，对比了Ross和Unger、Romstorfen和Eytelwein等比例公式的计算结果，指出选择不当公式会导致严重误差。
The article discusses the problem of defining borderline values of technical wear of a building and/or its components. Formulas and methods of defining wear have been highlighted, and an example has been presented, where the calculations were made according to proportionality formulas: Ross and Unger, Romstorfen and Eytelwein. While analysing results, some differences have been pointed out in the assessment of the degree of wear, depending on the time lapse and selection of a calculation formula. Selecting an inappropriate calculation procedure (depending on the focus on an element), and incorrect manner of defining technical life span of an element or a whole building leads to serious errors. The justifiability of the above statement has been proved in the summary, where a comparison of element use, according to different calculation formulas, has been presented in a graphic form.
