Hello. Dis goes out to all civil engrs in d house. Jes felt we cud do a brief daily update(notes,illustratns,pictures...) of our site or office experience, as dis may provide an avenue for odas to learn few tns.
Bt first of all, we can introduce ourselves-name,organisatn,yrs of experience, etc.
As for me, Mutiu, a fresh graduate frm OAU n currently aving my nysc wif Julius Berger Nig.plc, Abuja.
Expecting +ve responses pls. Tanx

Nice. I dont know may be am permited to post in this thread, am a building tech student @ unilag presently in 300l, i will like to know more of reading rebars from the plan and placing of each specified bars at it position. Asap.

Am guessing 'reinforcement steel bars' is wht you meant by 'rebars', in building structural design drawings, the members are categorized grid like, where you have eg column B2, this means column on the intersept of grid B and grid 2. This is how i illustrate the members on my structure for easy interpretation. So, you should refer to the structural drawing not the building plan for better understanding and interpretation.

thanks. How will you calculate and know the numbers of bars needed for a slab

ajayioluwatobi: thanks. How will you calculate and know the numbers of bars needed for a slab

It depends on the slab span, that's if its a one way or two way slab, one way means you will be designing the bars in one direction ( bottom reinforcements) and two ways slab, you will be designing for both the top and bottom reinforcements ie x and y direction. You have to determine the type of slab for you to know the formular standards to use in youя design. What's the span of the slab you want to design? Length and width? If the sum of the dimensions divided by two is <4.5m (one way slab) you design for only the bottom reinforcements but if its >4.5m (two way slab) you design for both the top and bottom reinforcements. There are so many other factors to consider in structural designs, so you need to be extra careful with the number and spacing, c/c, of bars you use, it must be from youя design that you get the figures, not by guessing.

How do you place and space rods in a panel, eg 21-R1201-225mm c/c B or T.

You see it's quite simple. If you're designing a 2 way spanning slab using the limit state design method, you design the slab to meet the limit state requirement and serviceability. So from your design you ensure that the reinforment you provide on both spans is adequate. So say you provide what u wrote above for the design, it means you provide for that span 21 mild steel bars at spacing of 225mm centre to centre. You should also not forget torsional reinforcement at the discontinuous edeges and reinforcements that you provide at the continuous edges. The lengths of those reinforcements are important and are dependent on the length of the whatever span the slab has.

Can you enlighten me on Doubly reinforced beam : 1-y2003+2-y1604, 2*25-R1005-240mm c/c - Double

Pls i need help am a civil engrn. Student frm yabatech...i just finish my ND so i need a company to do my Industrial Attachment...any body that can help or with info. Dis is my email raji_ola34@yahoo.com, 08020714100

ajayioluwatobi: God bless u

Can you enlighten me on Doubly reinforced beam : 1-y2003+2-y1604, 2*25-R1005-240mm c/c - Double

It means you should place 1 high tensile 'Y' steel bar, 20mm, with the serial no '05' (refer to the structural drawing for the serial no) + 2 'Y' steel bars, 16mm, with the serial no '04' and bind for shear reinforcement with 25, 2 to 1, 10mm mild steel bar, spacing 240mm center to center.

You can do a lot more by using one of the various structural analysis software out there. e.g.

Autodesk Robot Structural Analysis(very flexible)

Autodesk software and StaadPRO, which one is more flexible for a beginner to use? 'Cuz i want to learn any of the structural analysis softwares.

Go for Autodesk Robot or Tekla structures. I never fancy StaadPro.

Autodesk Robot is very flexible and comes with a plug in that enables a direct interfacing with Autodesk Inventor, Revit and AutoCad structural Detailing.


I used StaadPro and Tekla 14 but dumped them when I discovered Autodesk Robot Structural Analysis software.

My verdict? Autodesk Robot structural analysis all the way.

Autodesk Robot Structural Analysis it is then. Can i deal with the software on my own? Or should i get a tutor for the basics? U have a link for me to download it? Or i should just buy n install via PC software dealers? just give me ya views. Thanks a lot for the info.

You made a wise choice by choosing Autodesk Robot. Your ability to design and analyze structures must be enhanced within few weeks. thank me later.


You should get a crack version in Lagos, computer village or get the license if you are capable of doing that.

About learning, I suggest you watch many YouTube videos you can or buy online training tutorials. You should be able learn it yourself as a trained civil engineer( Just an extension of what you already have in your brain)

I can still help you out if you want a physical contact( with payments) or start a thread here if you want FREE online training supports from me( I'm willing to teach you here from A to Z for FREE)

I'm a CAD tutor and very versed with them. I use tons of software at professional level cutting across several engineering field of architecture, civil, production, mechanical and construction. I write and run scripts, cos no single application out there is perfect. when designing houses, I literally build them in computer 3D with all dimensions of as-built. when designing structural members I teleport myself into the world of CAD. I use 3D MAX for most rendering and animation with mental ray cos Vray normally drain computer resources. I use inventor or solidworks for mechanical design.

One more thing, autocad is only good for drafting 2D. The 3D modeling in autocad is NOT flexible and can be chunky. Can't deform curves to higher degrees.

Though, people consider it first stop for any engineer or draftman. The 2011 version came with mesh modeling of 3D which can come handy but still several years behind other packages with B-spline or free form designing tools.

The 2013 is improved upon greatly. one thing you have to give to autocad is universality and general acceptability across most industries.

Another advantage of starting 3D in autocad is the tools are interchangeable with other higher Autodesk software.

E.g thesame icon in autocad is replicated in inventor, so you will have less concern with acquaintance with newer icons. The UI is similar with other Autodesk packages like Autodesk 3D civil, Autodesk inventor, Autodesk 3D plant, Autocad detailing.

what about Prokon (Structural Design Software)........

i got youя email id. You'll get a mail frm me soonest. i just visited ya blog, quite interesting and awesome i have to say. i was already looking forward to meeting you till i got the info that you are not based in Lagos. Sad news. Youя designs are very diverse and dynamic, I have a lot to learn. Most firms request for proficiency in StaadPro, that's why i was leaning towards that earlier. What are youя views on that?

Secondly, am a Civil Engr that want to venture into FEED (front end engineering design) in the oil and gas industry viz subsea, pipeline, platform designs. Which design programs would you advise me to learn?

How did you start? i mean, youя blog is just soo interesting with all those designs, modeling with , if not, all the design softwares i've heard of + soo many that i didn't know existed. The building designs is what i'll love to learn personally for the freelance project i've been planning to start.
Let me stop here with the questions 'cuz i can go on and on...will ask more via email.
Thanks a million.

QUESTION:
(1) why in the bridge pier design is circular.
(2) what are uses of drawing shear force and bending
moment diagrams..

please give best answer..

ajayioluwatobi: QUESTION:
(1) why in the bridge pier design is circular.
(2) what are uses of drawing shear force and bending
moment diagrams..

please give best answer..

wif d little i know bout bridges,nt all bridge piers are circular, there are other shapes of bridge piers. Bt d design might always circular cos of even transmission of load. Since there are no sharp edges, d load will b transmitted uniformly thruout d pier sectn. Dats d little i know. Expectn replies as well.
2) shear force n bmd are used for designing concrete structures against shear n flexure. The bmd gives d values of moments d structure is expected to b subjected to, usually to determine reinforcement bars to b used against tensile forces, n sumtimes compression. While shear force is used to design against shear(cutting off due to shear force) n dey can also b used in determining deflectn.
Expectn more answers also
