Structures from first principles!
This fourth article in the series on concrete bridges examines the special types of concrete bridge — previous articles described all the cast in place and precast options, Concrete cable-stayed, extradosed and stressed ribbon bridges are all described here, together with the special features of concrete footbridges and railway bridges.
Structural steel elements are amenable to failure due to lateral torsional buckling, when measures that recognizes this risk have not been considered in design. This article briefly, explains how the structural engineer can deal with lateral torsional buckling when analyzing steel structures.
This article provides guidance on how to design steel columns subjected to combined axial compression and bending to EC3, using the simplified expressions in the IStructE manual for the design of steelwork buildings.
Despite timber being one of the earliest structural materials around and its globally recognized status for sustainability, the tallest Timber building is still the 18-Storey building at the University of British Columbia, why?
![[Viewpoint] Why Do Buildings Fail in Nigeria?](https://structurescentre.com/wp-content/uploads/2023/04/Ikoyi-collapse-330x288.jpg)
In 2022, Nigeria recorded over 61 incidents of building collapse in 2022. As I write this article, I don’t know of any forensic report that has been made public on any of these incidents, or do you?
A spiral staircase is a type of staircase that follows a helical or circular path, with each step or tread positioned around a central column or a post.
When unauthorized changes occur on construction sites, they give rise to a conflict of interest, particularly in design-built projects.
Slab rafts are the simplest form of raft foundation typically encountered in practice. The motivation as with other raft foundation is to bring applied pressures to acceptable limits.
Precast bridges are highly favoured, where the speed of construction is very crucial or generally where the cost of procuring precast is justified by a shorter construction programme. This article discusses the different forms of precast bridges, typically encountered in practice.
Items relating to “boundaries of duties” constitutes a vast proportion of the frustrations and misunderstanding, and claims made against engineers. This article identifies and expatiate on the six boundaries of duties which an engineer must define in a fee proposal.
