I am in need of designing the reinforcement steel for a simple slab for a home I'm building.
Slab depth must be 15cm (6")
Live load: ~3 kn/m2
Walls/beams 20cm wide
The slab is not supported on all four edges. Edges A and B are not supported.
Please see image attached, red area represents the slab needed, the remaining area will be precast slabs.
Can someone please recommend a steel reinforcement arrangement?
I am thinking maybe something like this but slightly modified by adding beams on all edges (but not sure): http://www.youtube.com/watch?v=vKha05T528U

Hi, I have a problem with TOPCON GTS 230N, after I do some data collection and need to move my instrument position I cannot make connection between the two sets of data I collect. Please anyone have any idea about it? I dont know the steps that I have to follow in order to do so.

The title of our topic would be: "The Distributing of Fire Rating on reinforced Concrete structure due to Elevated Temperature"
SHORT DESCRIPTION: This study aims to produce a reference table of the initial rapid assessment of the flexural serviceability of the reinforced concrete beam in a residential-type structure. The RC beams will be subjected to fire with elevated temperature on certain time durations. The data that will gathered will be used as the basis in designing structures considering the possible effects of fire in the resisting capacity of reinforced concrete beams.
is this study valid to be defended? Thank You. -from the Philippines.

Hi! We're already at our fourth year in structural civil engineering and I was hoping that I can get help here. We're having problem regarding on our thesis title. We don't have yet a title :( and the deadline for chapter 1 is near. We need to come up for an experimental thesis and have a product. Can you please suggest a good thesis title? Thank you for your response.

I have a question for everyone. I am compiling a list of standard inlet catch basin name and size for each state. For instance, here in Washington where I work, our Type 1 CB is the first inlet for stormwater and is 22" x 26" interior. Would you mind sending me the dimensions and name of your typical CB size for the initial storm inlet for your state?

Hello World !!! I am a Civil Engineering Student...
I have assigned a Project of Designing an OFFICE BUILDING using Structural Steel and comparing it with concrete design of the same building in different aspects. So, I need CAD Working Drawings of an OFFICE BUILDING of (10 to 15) Story and Rectangular in shape. I have Searched the whole internet but nothing found useful.Anyone in the world to help me.I'll be great thankful till my death and keep the privacy of the drawings...Thankyou Email : firstname.lastname@example.org

I have been working on a project where i am facing an problem wit is as follows :
Reservoir water has become acidic of ph 3+ due to existence of coal mines on the upstream side of the dam. The concrete of the dam has eroded & further deterioration is continued which make the dam stability in danger . To save the front face of the dam , necessary barrier is required to avoid further deterioration.
What type of protective measures should be taken to solve this problem under water condition ?
The Thickness of steel plates of the panstock has reduced by 3 to 6 mm and there is a possibility of bursting of the pipes under the hydro static water pressure. The panstock pipes are lying under ground at about 30 to 40 degree of the power house and it is not possible to replace the whole length with further steel lining .We are of the view that some kind of polymer coating be done inside the panstock under wet condition so as to achieve the required strength of the pipe to the designed value. It may be suggested what kind of polymer coating maybe done & whether the thickness provided may achieve the required design strength of the pipe by bonding with the steel as one unit.

Next fall will be my last year on my civil engineering degree. I am specifically interested in structural design and construction. I am starting to think about where I want to start my career. Hence, I would like know about the current opportunities that are arising in the field and any personal experience that could give perspective and an edge. All information is welcomed on any of the civil engineering field and personal options/anecdotes would be very interesting, I would just like to get a feel for the day in the life of a civil engineer.
Thanks you very much!!

hi friends I am a fourth year student. we r doing main project on bitumen stabilization of clayey sois. this project was not done before by any other students so we dont have correct approach to how the soil is getting its strength. if anybody have an idea about this please comment. we googled many sites but we dont get any useful matter. please post the links of journals related to this .thanq

I'm a student so am still learning, anyway I think I know what a continuous beam is: a beam that spans more than two supports. I have a project to design a building however going through lecture notes for preliminary design I have come across this:
'Based on the practice of experienced designers a number of “rules of thumb” have been suggested to propose the initial size of members. For instance some designers use the following “rules of thumb” for the preliminary sizing of RC beams:
for simply supported beams: h>=L/16
for beams with one end continuous: h>=L/18.5
for beams with both ends continuous: h>=L/21
for cantilever beams: h>=L/8
where h= height of the beam, L= length of span'
Now I can't seem to find anything anywhere else that differs between continuous beams, and nor can I think what it might mean. I feel stupid asking this but no one seems to know and my lecturer has been ignoring me :/ I possibly thought he may not mean a continuous beam as such but be referring to an overhang but given that the building I am designing is a general grid layout I don't think anything is overhanging so am just a bit puzzled. Any help would be greatly appreciated :)
