Abstract

In the desert area of Libya, an incident involving the collapse of several telecommunication towers became a very serious problem. Such incidents can be prevented by taking adequate measures to strengthen the tower structures. However, most towers that needed to be reinforced are located in the middle of the desert with frequent harsh windy conditions and are difficult to reach. Any construction work at these locations faces great challenges in mobilization of heavy equipment as well as materials and personnel. Therefore, it was essential that any remedial measure should be simple and easy to undertake. In this paper, we present a new structural steel reinforcement methodology that is both simple and easy to implement, but yields effective and guaranteed results. It does not require any drilling or welding of the existing tower structures. Such new and innovative methodology have now been employed in the Libyan Desert, which were extensively tested and found to be very effective and resulted in significant savings to the clients.
