Applying Value Engineering Technique Using Building Information Modeling at Underground Metro Station

Simulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7

In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied. The heat release rate is based on a quadratic f...

Design, Implementation and Experimental Results of a Wireless Sensor Network for Underground Metro Station

Wireless sensor networks provide a prominent approach for environmental monitoring system in many different scenarios. Typically, sensors communicate through a mesh network architecture, in which each device functions also as a relay for other devices. The usage of multi-hop wireless paths raises the challenge of achieving robust communication and low energy consumption while optimizing the sys...

Knowledge based Bridge Engineering - Artificial Intelligence meets Building Information Modeling

In the research project “KBE4Infra”, knowledge-based engineering (KBE) techniques for capture, storage and reuse of engineering knowledge in bridge engineering are investigated. A rich data source of bridge engineering knowledge, are Bridge Management Systems (BMS). The work present addresses the question, whether it is possible to gain knowledge by the use of data in bridge management systems ...
