NOVELTY - The truss tower has at least three columns (1), included in each structural level, which are precast in different types of concrete. Each column has an inclination angle of less than 15 degrees towards a vertical axis. Each structural level includes multiple cross beams (2) which are precast in different types of concrete. The columns and cross beams cross at corresponding joints (3).    USE - Truss tower for supporting e.g. wind turbines, overhead power lines or communication lines, water tanks, bridges, oil exploration equipment.    ADVANTAGE - Enables adoption of a system that is not conditioned by current dimension limits in transportation routes, thus allowing the freedom to choose the geometry of the tower and enabling the structural optimization of the system, both in term$ of its resistant capacity and the control of its natural vibration frequency. Provides the ability to build very high towers capable of supporting high-power turbines onshore and offshore. Improves structural damping and dynamic behavior, thus allowing the reduction of fatigue actions and contributing to the increase of equipment operating life and cost savings on maintenance. Connections between components are reliable, tested, maintenance free, easy and quick to implement on site, thus providing all good effects of structural monolithism. Ensures excellent response to seismic actions due to high ductility of all components of the tower and its high structural damping which increases in situations of extreme loads, thus allowing the tower to absorb and dissipate energy in the event of an earthquake. Exhibits excellent stiffness and vibration frequency of the tower to reduce the requirements for foundation stiffness, thus reducing uncertainties associated with the deformability of the ground, and allowing cost savings of the foundation, especially in soft ground. Allows the large weight of the tower to provide a stabilizing effect and allow reduction of required foundation weight, thus further reducing costs. Ensures high speed assembly by allowing use of very long components and appropriate quick systems of implementation of structural connections. Provides a space in the base of the tower for mounting of equipment in a single level, without constraints of space. Provides simple, cost-effective and reliable connections of the columns to the foundation. Enables easy mounting of equipment to the components of the tower. Reduces need for maintenance, and ensures higher durability of concrete structures compared to steel towers, especially in maritime environments, due to the protective action of an appropriate reinforcement concrete cover. Improves durability with the use of high-performance concrete in the structure of towers for wind turbines. Ensures less noise due to the damping effect of the concrete. Reduces carbon dioxide emissions in the manufacture of tower. Ensures high aesthetic quality due to its geometry and the good industrial quality of the finishes of the components produced in a factory. Enables good integration of wind turbines in a landscape, and allows recycling of the materials of the tower.
