Lattice Towers

The use of lattice towers for the transmission of high voltage electricity, and to provide a high platform for the transmission of data, presents structures that are lightweight but highly effective in performing a function that does not require a compromise for inhabitants. As a result of this requirements, lattice towers can be dynamically sensitive and many collapses have occurred. As towers age they may become more sensitive. First indications of a problem may be as simple as difficulties with reception for data transmission, but can progress to debris appearing on the ground. STRAAM has expertise in measuring the response of such towers to wind excitation, and calibrating finite element models, so that the response for the design condition can be compared with original assumptions. Such an analysis can be crucial in determining maintenance programs or whether more equipment can be attached safely.
