Zašto većina država koristi sistem upravljanja mostovima?

The Bridge Management System (BMS) includes a systematic approach to the organized monitoring of the condition of bridges, especially the registration of defects and damage, and the performance of all activities related to maintenance and rehabilitation during the operation of bridges. In doing so, the owner of the bridges is provided with documentation to make adequate decisions on focusing the budget on individual bridges or the network of bridges according to priority. This paper analyzes some management systems abroad with a brief historical background. Until the 80’s of the previous century there was an active work on the introduction of BMS in Serbia, however since 2010 there has been a pause in the development and implementation of BMS. This situation should be overcome as soon as possible because of the general benefits of well- established and implemented BMSs for the road network and traffic improvement.Sistem za upravljanje mostovima (BMS) obuhvata sistematizovan pristup organizovanog praćenja stanja mostova, naročito registracija defekata i oštećenja, i obavljanja svih aktivnosti vezanih za održavanje i rehabilitacije tokom eksploatacije mostova. Pri tome se vlasniku mostova obezbeđuje dokumentacija da donosi adekvatne odluke o usmeravanju budžeta na pojedine mostove ili mrežu mostova prema prioritetu. U ovom radu su analizirani neki sistemi upravljanja u inostranstvu uz sažet prikaz istorijata. U Srbiji je i pored aktivnog rada na uvođenju BMS-a, sve do osamdesetih godina prošlog stoleća, a od 2010. godine nastao je zastoj u razvoju i primeni BMS-a. To stanje bi se moralo što pre prevazići zbog opšte koristi koju dobro postavljen i primenjen BMS donosi putnoj mreži i unapređenju saobraćaja.Zbornik radova Dvanaestog naučno-stručnog međunarodnog savetovanja Ocena stanja, održavanje i sanacija građevinskih objekata, Vrnjačka Banja, 29. jun – 1. jul 2022.

Probabilistic analysis of bearing capacity of piles with variable parameters in cpt test and calculation according to the requirements

A probabilistic concept for determining pile bearing capacity is presented, taking into account the variability of CPT test parameters and methodology of calculation according to the requirements of Eurocode 7 (EN 1997-1: 2004). Based on a single initial (real) CPT test, a larger number of generated (simulation) CPT tests are introduced drawn from solutions of statistics and probability theory. Research has found that the best solutions are achieved using the DA 2 design approach for n(CPT) > 10 tests. Taking into account the deterministic and probabilistic approach in the analysis of pile bearing capacity, it is found that for the DA 2 design approach, the ratio of pile bearing capacity obtained from simulation and the capacity as determined through three methods (Mazurkiewicz, Van der Veen and hyperbolic approximation) is Rcd, /Pu = 1.148. Using the reliability index, the following values of partial resistance factors are obtained: λ, s /P 1.1, λ, b /P 1.1, which also points to the DA 2 design approach
