BI-SERIAL CORRELATION OF CIVIL ENGINEERING BUILDING ELEMENTS UNDER CONSTANT TECHNICAL DETERIORATION
Journal Title: Scientific Journal of the Military University of Land Forces - Year 2016, Vol 179, Issue 1
Abstract
The article presents a method of determining numerical relationships between defects occurring to some elements of the analysed structures, expressing their maintenance conditions, and the magnitude of their technical degradation. Unmeasurable (qualitative) variables, i.e. individual defects with dichotomous values, and measurable variables (quantitative), i.e. the extent of technical wear of particular structures, were identified. An attempt to numerically express the correlation between them was made. In the calculation of the strength of this relationship, the method of determination of the point bi-serial correlation coefficient for different types of properties. The significance of this coefficient for a typologically selected, nonprobability sample was investigated. The results obtained for this sample were extrapolated to a uniform population of pre-war tenement houses in Wrocław.
