A short discussion on chemical fasteners, continuing our series of posts on fastening technology. Chemical fasteners transfer tension load to the borehole mainly via adhesion. The components are connected to one another to form an adhesive bond. Advantages: High load-carrying capacities No expansion forces (ideal for fastenings near the edge) Suitable for anchoring in solid […]

Assuming that we can keep the Pandas at bay, should we be looking at replacing steel with bamboo? Can bamboo telecommunication towers be sustainable and economical? Telecom towers are usually fabricated using steel because steel has very good strength. However, due to its tightly packed fibres, bamboo has superior tensile strength over steel. Producing steel

Rooftop stub towers, a solution that has gained popularity for its ability to overcome space constraints and improve connectivity in urban environments. When performing structural analysis on stub towers, it’s easy to focus solely on the tower structure, headframe and secondary steelworks. However, it’s crucial not to overlook the primary structure of the building itself.

EMA Poles are common telecom structures in city centres. EMA poles are usually held by standoffs attached to a plate and connected to a wall through anchor bolts. The forces generated causes the anchors to want to pull out from the wall. Historically, these anchors are held by chemical resins injected into the wall. Click

Lattice towers can be braced in various configurations (see image) but have you ever wondered why a particular configuration is selected? Braces are needed to keep a structure stable and prevent it from swaying or drifting since most towers act as a cantilever system. They transfer lateral loads from the tower to the ground and

As a structural engineer, it is easy to become so focused on design and analysis that you neglect other valuable skills that can help you excel in your field. While knowledge of codes, standards, and structural theory is essential, it is equally important for engineers to have a diverse range of skills and well-rounded knowledge

Deflection in telecommunication structures refers to the deformation or displacement of a structure from its original position under load. Deflection is a serviceability limit, that is, it does not automatically constitute structural failure, thus there are often differing requirements on the acceptable levels of deflection. There are typically two categories of deflection limits considered in

“Why do you consider the safety factor of 1.5 instead of 1.3, or why deliberately increase the pole size to CHS114.3 if CHS88.9 would work? – It is for conservatism.” Sometimes we like to use of the word “conservative” to imply that we’re assigning values that we know to be too large (or too small,
