Rubbiish: Architect who pulls up such design should be able to get a Structural Engineer who will put up the structural aspect. So it is not beyond the limits of the Nigerian Engineer. It is only beyond the limits of the individual thinker. 1 Like |

bixton: Also the clients should bring the design too. Let’s even start from there. Because non of my clients have agreed on a design with such a cantilever. Anyway I Dey wait for @Egunmogaji . I believe say me and my Oga go do this kind of building together one day. |

Aventures: Aventures, for accuracy, how long is a soil test really good for? Can one use a result from a soil test done 2-3 years ago? My other question is, do I need to know the type of structure I want to erect before carry out a soil test or the test can be done and then give my structural engineer whenever I am ready? |

bixton:@bold So all the structural designs done by our structural engr. were given to them by the architect who designed them? Why must the architect be the one to get the structural engr in this case? |

Rubbiish: I don't see anything too difficult about that cantilever, look at the top of it, did you notice how it is reduced to draw back some weight?

Androidking:Is the bold more important than the safety of the occupants? Once a cantilever is involved, all measures to make it work should be adopted, even if it means impairing aesthestics. This is Nigeria, our engineers are still evolving, they will get there. I was just talking about a post with a loaded cantilever...Cantilever is a big challenge for engrs, but not to architects, because to the architect is drawing, but to the engrs is more than drawing. To do cantilever no be beans ooo...Even to the whites, they still struggle with it. The burj al arab is classic example... 1 Like |

spyder880:True sir... But the extension at the base & the wall on top of it rose my observation. Most cantilevers we build here in nigeria extending more than 1.2m solely serve as balcony & not loaded with walls like i saw in that pic. 1 Like |

Rubbiish: Chairman Ah Ah!! give us some credit ooo. The only thing I see about this building is the genius thinking in its the architecture. Do you know that the Extension is Most likely not carrying any more than 40% of the Load and is also most like the 40% its carrying is still getting support from the Top ? 2 Likes |

Androidking: I think the problem is most of these building don't have structural design and if they do, the designs are not properly done. Before I can answer your question, I will like to define and differentiate some terms that are interchangeably used from a structuring engineering point cantilever slab: when the slab of a building or other structural member shootout from a beam perpendicular to the length width of the adjacent beam (a layman definition) Overhanging slab: when a part of the slab is hanging out from an inner slab, where the two slab share the same beam at a point cantilever beam: look up to the cantilevered slab above Overhanging beam: look up to the overhanging slab above. the major reasons while most of the building cantilever or overhung have such load is the presence of loaded slab at the edge which exacts too much point load, thereby increasing the moment and share at such end. The better arrangement is to have the slab cantilevered out without a column on top, where the slab will carry only the wall load of one floor. If there is a need to have a wider slab, The slab can be accompanied by a beam which can be concealed ( raft or waffle slab) or shoot out below. From experience, the best approach is to have an overhanging beam that extended into the slab thereby neutralizing the effect bending moment on the beams and columns 1 Like |

abdulwastecx: Eku Laakai Sir, Well dissected , my question on this cantilever discourse to you sir are. 1.what is the relationship between the quantity of iron rods used in cantilever and decking in terms of sizes of iron rod. 2.-What is the ideal length of a cantilever shoot out from the decking in terms of feels or metres Thank you |

The importance of a cantilever cannot be over emphasized in shooting out of the upper structure of a building. I personally love attic designs and structure as an architect but some clients are selective about this. What mutafau55 said shouldn't be misunderstood as the another person reacted,it's the matter of choice and other personal reason(s). Got some time today and some days back, really following this interesting discussion. |

Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by abdulwastecx(m): 6:11pm On Feb 15, 2018 |
Flaghouse1: Nice question sir 1. There is no relationship between the quantity of reinforcement used in a cantilever and the that used on the adjoining slab (the decking). What we have is the percentage lapping length of the cantilever slab reinforcement ( mostly top bar extended into the adjoining slab). this lap length are taking to be 1.5L ( where L is the width of the cantilever). There is no ideal length of a cantilever because in structural engineering you only provide a solution to the problem posed by the architect. The architect will make the design based on the need of the client, for example, some cantilever is to serve aesthetics function like long balconies while some serve functionality purpose, like extension out to add extra space to the living area. experience has shown that for a continuous slab construction with an overhanging slab (cantilever slab), optimal design moment is achieved at 0.2L ( where L is the length of the slab adjoining the cantilever. so, for a slab of 6m, the width of the cantilever adjoining it will be 0.2 x 6000 = 1200mm ( 1.2m) 6 Likes 1 Share |
