| | Summary: |
| | Bridge Management System (BMS) represents a rational and systematic
approach to organizing and conducting of all activities related to bridge maintenance.
Main goal of BMS is helping the bridge owner to make an optimal decision with respect
to bridge maintenance budget, whether it is dedicated to one bridge or to group of bridges,
by securing that the decision is made on the basis of Life-Cycle Cost (LCC) estimates. The
structure of BMS is based on condition rating and Bridge Database (BD), Deterioration
model (DM), Cost Model for evaluation of costs and Optimization Model for choosing the
most rational maintenance strategy. Relationship between bridge condition rating and
DM with maintenance costs within BMS is very important. Predictions regarding future
intensity and rate of bridge deterioration depends on multitude of factors and it is a
consequence of several simultaneous actionsand deterioration processes (DP) which
need to be included into DMs. DMsare mostly based on modeling of physical and
chemical actions and processes or they are based on statistical analysis of large number
of data regarding the condition of existing bridges, or on artificial intelligence models, etc. Stochastic models based on Markov processes are applied within more advanced contemporary BMS. Due to social and economic circumstances and lack of financial resources over the last two decades in Republic of Serbia bridge maintenance was neglected and creation of BDwas discontinued. The paper deliberates some aspects of technical models within BMS, with DMs being pointed out, development of BD within
bridge maintenance in Republic of Serbia and it gives an overview of sophisticated BMS and current advances in this field. |
