Performance of base connections for concrete segmental communication tower

Demand for communication towers has increased in the last several years due to revolution in the networking domain. Recently, advancements in the field of material and structural engineering have yielded several types of concretes such as ultra-high performance fibre-reinforced concrete (UHPFRC) wh...
