The Spanish company Lasser Eólica specializes in evaluating wind data. Their services also include the design, documentation, and construction of guyed masts worldwide. The main goal of the tower structure is to achieve maximum wind permeability. Therefore, the towers consist of tubular steel trusses with a triangular ground plan. For each plane, three sets of prestressed cables are used to stabilize the tower at different heights.
To avoid measurement errors during data collection, measuring devices such as the anemometer and weather vane must be positioned by level arms at a certain distance and a certain height from the tower surface, according to ISO 61400-12-1.
Design in RSTAB
The Lasser Eólica technical team designs the relevant load cases such as ice and wind loading depending on each individual project’s location. Afterwards, the data are entered in RSTAB using customized data sheets. The load is entered with the TOWER Loading add-on module. For the standard design, together with the global stability behavior, the team additionally utilizes the add-on modules STEEL EC3 and RSBUCK.
