Structures from first principles!
The assessment of floor vibration concerns how the mass of its supporting structure moves when subjected to an imposed load. This is determined by ascertaining the natural frequency of the supporting structure to the floor, which is stated in Hz (cycles per second).
The Comet air crashes should teach and remind all engineers that, while all the analysis and design tools might be at your disposal, an engineer can only analyze and truly design for the situations they can actually imagine.
This second article in the series on temporary works discusses temporary works failures and how structural engineers can learn from them
The justification for combining loads from two or more super-structural element typically stems from restrictions. For instance, where the columns are closely spaced such that independent pile caps are impossible to construct as a result of overlapping.
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.
