Structures from first principles!
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?
The principle of virtual work sometimes known as the “unit-load” method was developed by John Bernoulli in 1717. It is a direct application of the principle of conservation of energy
Thus, one of the methods of ensuring lateral stability and avoiding excessive lateral deflection is by deploying shear walls across the width of the building to resist the lateral forces.
Flat slabs are reinforced concrete slabs supported directly on columns, without beams. They are sometimes thickened at the columns to form column drops.
Introduction This post concerns the application of lateral loads to barriers and wheel axle loads from vehicles. The nature of this type of loads may…
Introduction Before a column can be designed, the actions to which it must support must be determined. This includes the axial compressive forces and bending…
Introduction Moment redistribution must not be confused with moment distribution, as the two terms are distinctly dissimilar in meaning. Moment distribution is an approximate method…
