20.500.12556/RUL-89156 Vpliv vremena in izkušenosti pregledovalcev na objektivnost določanja stanja premostitvenih objektov tekom periodičnih pregledov magistrsko delo The impact of the weather and the experience of the inspectors on the objectivity of determining the state of bridging objects in the course of periodic inspections Na vseh premostitvenih objektih se zaradi zagotavljanja njihovega ustreznega stanja izvajajo periodični pregledi, katerih glavni namen je določiti oceno stanja. Zaradi subjektivnosti podajanja ocen stanja in posledično predpisovanja sanacijskih ukrepov smo se odločili ovrednotiti vpliv različnega vremena v času izvajanja pregleda ter izkušenosti pregledovalcev. Vizualne preglede objektov smo izvedli na treh različnih armiranobetonskih premostitvenih konstrukcijah. Za namen magistrskega dela smo razvili ocenjevalno metodo, ki je kombinacija slovenske in ameriške metode. Za ovrednotenje vpliva izkušenosti pregledovalcev so v raziskavi sodelovali trije absolventi magistrskega študija gradbeništva, ki so tak pregled opravljali prvič, trije pregledovalci z Gradbenega inštituta ZRMK, ki nimajo dolgoletnih izkušenj, ter trije izkušeni pregledovalci z Gradbenega inštituta ZRMK, ki preglede opravljajo že več let. Vpliv vremena pa smo ovrednotili z ocenjevanjem objektov v suhem stanju v sončnem vremenu ter v mokrem stanju po obilnejšem deževju. S pridobljenimi rezultati smo ugotovili, da so konstrukcije najmanj strogo ocenjevali pregledovalci z izkušnjami do 5 let, ostali dve skupini pa sta ocenjevali strožje. Znotraj skupine so najbolj enotno ocenjevali pregledovalci z največ izkušnjami. Z analizo rezultatov nam ni uspelo dokazati povezave med vremenom in višino podanih ocen. To ensure proper state of construction, periodic inspections have to be carried out on all bridging objects. Due to assessment subjectivity in the examination process and consequently also in determining restoration measures, we decided to evaluate the influence of weather conditions at the time of inspections as well as inspectors' experience upon assessment.Visual inspections of the structures were carried out on three concrete bridges.For the purpose of the Master thesis, we have developed a method of assessment, which is a combination of Slovenian and American methods. To evaluate the influence of the inspectors' experience, the following groups of inspectors participated in our study: three final year students of master program in engineering, who were participating in this kind of inspectionfor the first time, three inspectors from Building and Civil Engineering Institute without many years of experience, as well as three experienced inspectors from the same Institute, who have performed this kind of inspections for many years. We evaluated the influence of the weather by assessing the object in dry state in sunny weather and in wet state after heavier rains. With obtained results, we found out that inspectors with less than 5 years of experience did not evaluate as strictly as inspectors from the other two groups. Within the group, inspectors with the most experience evaluated as one. When we analyzed the results, we could not find a connection between the weather and the rate of the grade. gradbeništvo magistrska dela premostitveni objekti pregled stanja izkušenost pregledovalci skupna ocena podvoz sanacija most vmesni oporniki viadukt civil engineering master of science thesis bridging objects inspection of condition experience inspectors common assessment underpass true false false [J.
