Estimation of the value and the variability of elastic modulus of concrete in existing structure on the basis of continuous in situ measurements

This paper contains the results of analyses carried out on the basis of continuously performed strain and “stress” measurements in the concrete pylon of the Rędziński Bridge in Wrocław. The purpose of calculation was to estimate the value and the variability in time the effeetive, elastic modulus of concrete in […]

Instructions for continuous observation of built features located in post-mining areas

The process of built features monitoring by measurement and analysis of selected physical quantities allows to track and evaluate their technical condition thereby eliminate potential hazards. The observed physical quantities should be selected so that the results are simply and unequivocally connected with factors affecting the buildings’ behaviour. Properly measured […]

Snow loads on structures

The article presents the problem of snow load of building structures in the context of the possibility of reducing the operating costs of buildings through the use of different measurement methods. Snow is the impact that for a significant number of buildings, particularly large-surface (mainly steel buildings), is a major […]

Measurements of deformations of the structure with vibrating wire sensors

The best verification of any theoretical solution is to examine it in terms of actual work. Despite the use of advanced numerical models and more accurate models of interaction, still a definitive answer to the question concerning the correctness of the solution can be obtained on the basis of research.
