AFRICAN TRADITIONAL ARCHITECTURE/STEEL PORTAL FRAMES

They can be made in form of solid web sections either of single standard section or compound section and in form of lattice frames.
The frame can be of fixed foundations- then we observe some economy in the consumption of steel to make the frame, they are more rigid, can cover longer span but at same time the statical display of forces in the foundation is more complicated. The other solutions are two or three hinged frames with lighter foundations.

a) Solid web portal frame; they are made of standard profiles, mostly I-beam. They can span the distance up to 60-80 meters, the depth to span ratio 1/38 – 1/40. The frames are placed at 6-12 meters intervals depending on the purlins.
They are easy to make and do not require much maintenance. At longer spans, prestressing used to improve the statical properties of the frame. Special cables or steel rods of high tensile properties are attached to the frame and post-tensioning is introduced.

b) Lattice portal frames- two-hinged frames may be used to cover the span of 60-100 meters and fixed frames may span the distance of 100-150 meters. The height of the rafter is 1/15 – 1/20L/L-span. Lattices frames are light but are difficult to make and troublesome in maintenance as control and repainting of many members consume lot of time and money. The frame covering longest span can be post-tensioned which improves the statical properties of the system and can diminish the depth of the rafter to 1/30-1/35L. Post-tensioning is also introduced to improve the assembly of the frames composed of more elements.

The picture displayed is an on-going project titled the AMAZING BUSH BAR. It is a steel portal frame structure braced with African bamboo. It’s a class of its own and rare in our immediate environment. It portrays a true African traditional architecture.
The class of building materials used for the construction is a combination of traditional African building material like bamboo, the mat, mud etc

Our next publication will show the completed project and pictures on the steps used to achieve this master piece.

The amazing Bush Bar #2

Imagine combining african tradition techque (using bamboo) and modern day construction( Using cement and concrete block), the result is mind blowing.

Antipate wonders from this combination.
