2D and 3D Headframe Analysis

Due to our extensive in-house structural design capabilities and experience, KA Engineering Group has been awarded many more headframe projects this year. Headframes are built up steel structures carrying multiple telecommunication equipment supported on various primary structures, like monopole, stub tower and, lattice tower. They come in varying shapes including turret, triangular, square, hexagonal and

Impact of Feeder Arrangement

Feeder cables can FAIL a lattice tower, through exceeding the structural utilisation capacity, if not arranged thoughtfully. Carefully planned feeder arrangement in a simple system can reduce the utilisation of the lattice tower legs by 15% and reduce the tower brace utilisation by nearly 40%! Without adequate forethought, a telecommunication system with 16 feeder cables

Brace Supports for EMA Poles

In wall mounted pole structures, the design loads on ancillaries, i.e. wind load and vertical gravitational loads, are transferred to the walls through the anchors.The anchor pull-out load is limited by anchor and wall capacity. In the event of pull-out load being higher than anchor capacity, internal load bearing back plates can be installed. But

Tower Strengthening Project

At KA Engineering Group, we analyse a wide range of structures from monopoles to lattice towers and everything in-between. We recently completed the analysis of  an existing 48m tower for the proposed addition of a 2-meter microwave dish. Using a combination of the information from previous site surveys, as-built construction drawings, and photographs, we produced

Anchors Embedded in Masonry

In wall mounted pole structures, the function of anchor bolts is to transfer design forces such as uplift due to wind or vertical gravitational loads to the masonry. KAEG employs advanced engineering best practices to more consistently design and analyse anchors in order to ensure the installation properly embody its requirements. The method of calculating

Freestanding Ballast Frames

The design of free-standing rooftop structure in accordance with design codes to serviceability criterion is a fundamental first principle design that can be completed by the old-school pen and calculator method, but the solution is often over- or under-designed. The designed solution must be adequate to ensure that the structure is stable against overturning moment
