Towers are important structures for installing radio equipment to emit electromagnetic waves that allow radio, television and/or mobile communications to function. Feasibility, cost, and speed of the construction are considered in the design process as well as providing stability and functionality for the communication tower. This study proposes the new design for construction of segmental tubular section communication tower with ultra-high-performance fibre concrete (UHPFC) material and prestress tendon to gain durability, ductility, and strength. The proposed mix design for UHPFC in this study which used for construction of communication tower is consisted of densified Silica Fume, Silica fine and coarse Sand and hooked-ends Steel Fiber. The prestressed tendon is used in the tower body to provide sufficient strength against the lateral load. The proposed design allows the tower to be built with three precast segments that are connected using bolts and nuts. This paper presents a novel method of construction and installation of the communication tower. The advantages of proposed design and construction process include rapid casting of the precast segment for the tower and efficient installation of segments in the project. The use of UHPFC material with high strength and prestress tendon can reduce the size and thickness of the tower as well as the cost of construction. Notably, this material can also facilitate the construction and installation procedure.

Developing offshore wind power can effectively reduce carbon emissions, and adopting large‐capacity wind turbines is an important way to achieve cost reduction and efficiency increase. With increasing power capacity, the hub height and rotor‐nacelle assemblies (RNA) load will increase significantly. Ultra‐high performance concrete (UHPC) possesses ultra‐high compressive performance, good tensile, fatigue, and corrosion resistance, and thus is an effective way to further improve the mechanical performance and economic efficiency of tall offshore wind turbine (OWT) towers. Evaluation of ultimate strength is an essential aspect of design for OWT towers, and the tower structure is mainly under the combined action of axial compression from the self‐weight and RNA loads and bending from the eccentricities of RNA and aerodynamic loads from the rotor on the tower top. In this work, the mechanical behavior of prestressed UHPC wind turbine tower columns under combined axial compression and bending was numerically investigated. The finite element (FE) analyses were carried out using ABAQUS, and the material and geometric nonlinearity were considered in the model, as well as the tensile strain hardening properties of UHPC. The FE models were firstly verified by the typical experimental results of UHPC hollow columns, reinforced UHPC beams, prestressed UHPC beams, and prestressed concrete‐steel hybrid wind turbine tower model. Then the parametric study was carried out, and the parameters included the control stress and number of prestressing tendons, rib number, diameter‐to‐thickness ratio of the UHPC column, steel ratio of longitudinal reinforcement, axial load ratio, and UHPC strength. The calculation methods for flexural capacity of prestressed UHPC wind turbine tower columns were finally proposed, and were found to agree well with the modeling results.
