In this study, a system for monitoring the structural health of bridge deck and predicting various possible damages to this section was designed based on measuring the temperature and humidity with the use of wireless sensor networks, and then it was implemented and investigated. A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) wa...

As the premier material in construction industry across the world, concrete has major role in the effects of construction to our environment. Consumption of concrete is very high due to extensive use of concrete in many structural applications. The rapid infrastructural growth in developing countries and production of many by-product as waste material making high role to concrete producers in i...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

This paper proposes a method for monitoring the structural health of concrete bridges in Iran. In this method, bridge condition index (BCI) is determined by analytical hierarchy process (AHP). BCI constitutes eight indices that are scored based on experts’ views, including structural, hydrology and climate, safety, load impact, geotechnical seismicity, strategic importance, facilities, traffic ...

The aim of this study is to design ANFIS model and Fuzzy Expert System for determination of concrete mix design and finally compare their results. The datasets which has been loaded into ANFIS contains 552 mix designs and has been based on ACI mix designs. Moreover, in this study, a Fuzzy Expert System has been designed. Input fields of fuzzy expert system are Slump, Maximum Size of Aggregate (...

In an effort to protect the quality of the water system, interest in non-point source pollution is increasing. Recently, studies of non-point sources pollution are continuing in relation to various land-use areas, but such studies have not been fully conducted in railway facility sites. Using monitoring data of railway bridge area with concrete road-bed, the runoff characteristics, pollutant un...
