The main objectives of the present investigation, focusing on the special inspection, include structural inspection and evaluation of the four selected bridge structures as well as determination of bridge repairs and maintenance. The scopes of work are as follows. 1) Visual inspection of the bridge structures to examine damages and deterioration, prepare damage mapping and bridge inventory records, and determine condition rating of the bridges 2) Materials testing to collect technical information, regarding material characteristics of the bridge ...

There are two objectives in the project of an evaluation of the implementation of the political development plan No. 1 (2008-2013): first of all to evaluate performance resulting from an implementation of the plan; secondly, to offer recommendations and guidance for the political development plan No. 2. To evaluate the plan, researchers employ an evaluation research framework by using both quantitative and qualitative method. It founds that an implementation of the plan has both strengths and weaknesses. For strengths, for example, an extensive ...

A main objective is to perform load test and evaluation of load-carrying capacity of steel bridge structures after strengthening. Nineteen railway bridges located along the route of north-eastern region are considered. A static and dynamic load test is performed based on a predetermined load using a number of hopper wagons carrying reinforced concrete ballasts and box girders with the total load equivalent to train load U.20. The stress ranges and number of cycles are determined based on the strain measurements and are considered in fatigue ...
