Structures from first principles!
Retaining structures or a retaining wall is any constructed wall that holds back soil a liquid or other materials where there is an abrupt change in elevation. Retaining walls have been used for thousands of years, in the construction of terraced fields on a steep slope, or a railway through a hillside, a retaining wall is used in some form or another.
For every structure, frame stability is an important area of consideration. Designers of structural steel-work were the first to recognize the importance of considering the stability of steel frames in BS-5950.
This article is concerned with the derivation and application of these notional loading, which is classified as Equivalent Horizontal Forces within the Eurocodes. The article also illustrates how the notional horizontal loads are incorporated into the design process.
Basement walls are essentially retaining walls which in most instances, in addition to the lateral forces from soil, pore pressure and surcharge must also carry axial forces due to gravity loads from slabs.

Timber posts are vertical elements, when utilized in any timber frame are principally subjected to both axial compressive actions and bending moments along one or both axes. In other words, a timber post is the equivalent of a column, but in this case the term ‘post’ refers to timber or steel.
This article discusses axial shortening and its causes, how they can be predicted, evaluated and mitigated. It would explain the measures structural engineers and building contractors may employ to counter its effect. It would also make references to the current codes of practices were necessary.
This article presents the design of concealed concrete beams, sometimes referred to as the “wide or strong band beams…
A truss is a triangulated assembly of interconnected elements, pinned at the nodes and typically having all external forces and reactions applied at the nodes (Figure 1). Trusses are extremely strong and a very cost-effective solution when compared to other structural options
![[Opinion] Choice of Structural form for a Monopitch Roof](https://structurescentre.com/wp-content/uploads/2021/07/featured-image-for-post-330x288.jpg)
You’re faced with the design of a steel truss for a monopitch roof spanning 18.35m. The roof is invariably enclosed hence is considered predominantly subjected to gravity loads, which scheme would you choose or consider more appropriate and why?
