This article presents the design of cellular raft foundation, a spread foundation arrangement with two way interlocking ground beams with a ground bearing slab in contact with the soil and a suspended slab at the top surface…

Steel portal frames are the most common and cost-effective structural solutions for single-storey buildings with gable-pitched roofs. In fact, about 50% of the steelwork in the U.K is used up in the construction of single-storey buildings, of which portal frames form the greater part…
This article presents the design of concealed concrete beams, sometimes referred to as the “wide or strong band beams…
Unlike members in axial tension, when structural elements are subjected to axial compression, they become vulnerable to failure through instability as a result of their geometrical properties rather than their material properties…
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?
Deciding the final choice of a bridge requires serious considerations, and depends important parameters, many of which correlates between construction program, cost and risk.
A significant opening within masonry walls will always require a lintel of some sort to bridge over it. In contrast to popular opinion, lintels are structural elements though classified as secondary structural elements whose primary function is to support the masonry that arches over the opening
The designer of a composite floor has a number of basic and obvious decisions to make, including what type of beam to use and what type of decking. He or she also has some more detailed decisions, such as the choice of propped or unpropped construction, whether the steel beams will be restrained during construction, and how will the upper surfaces of the slabs be levelled during concreting
Column base plates are provided beneath steel columns in order to transmit the applied design forces safely to the foundations. Steel columns are heavily loaded and their cross-sections are typically small…….
