155 Category 4: Special Projects 4 Owner Tennet General Contractor SPIE Engineering Office SPIE Controlec Engineering Construction Period 01/2016 - 03/2016 Upgrade of a power transmission tower for extra mobile devices. The power transmission tower is a big supporting structure that transports energy from electrical power plants to distribution cabinets, or connects different power line networks. There are different types of power transmission towers: start or termination tower, transposition tower and line deviation towers. The power transmission towers are also used to install mobile antenna devices to create a mobile distribution network. To install these devices in a power transmission tower, the tower itself has to be upgraded to be able to house these extra items. The power transmission towers were mainly designed in the 1960s and 1970s. The power tower of our project has the height of 44.2 m and the base of 11.6 m x 11.6 m. The SCIA Engineer model is a truss model. All members are hinged connected. The loadings (wind, icing, cable tension of the power lines) on the power transmission tower are designed according to the NEN-EN 50341-3-15, and also the loading combinations are according to this code. The output of the calculation is used to verify the capacity of the foundation. Moreover, the verification of the old NEN1060 code was done to check the overcapacity of the structure.
