We should not consider the amount of force at which the concrete finally broke off. Instead we must only take into account the force at which the first minute crack appeared. Because in the real world scenario prevention is always the best option.

That's very unusual type of failure. Even though the crack started propagating from the middle portion of tension zone replicating under-reinforced section, it seems here that steel ruptured at the end which shouldn't be the case. The final failure should have taken place via crushing of concrete in compression after yielding of steel bars. Did you figure out the possible reason behind this?

A universal modular strain sensor for steel and concrete Acousto elastic concrete strain sensors are used to detect the metrological Elongation or compression of steel building components as well as for measurements in reinforced and unreinforced concrete bodies used. The thickness of the sensor (diameter of the bolts) may be selected according to the strength reinforcement. www.ibj-technology.com www.prlog.org/12191357-universal-modular-strain-sensor-for-steel-and-concrete.html

Hey fellow Aussies, I think. Nice video, I'm doing some study on concrete and reinforcing and my obstacle now is finding the tensile strength of reinforcing steel, do you know of any data sources that the public can read. Also have you done any tests with high tensile cable and pre stressing of it?Also what university if at all?

I'm studying reinforced concrete now, and this was quite awesome. The beam held more than one whole ton of weight above what the calculations suggested. I'd qualify this as quite safe. Anyways, since it cracked exactly down the middle and from the bottom up, am I right in believing that this was an under-reinforced situation and the momentum was what killed it?

It was tension-controlled beam, so tension in the middle bottom part where tensile stress was enough for ultimate failure of steel killed it.

in instructure for concrete beam as or not RC beam for testing in failure test, we don't know what spectrum in decisiation for tectonic numeric if the style in thats product not check out to unabolition product?just hope this test maybe can solve the thechnology in EMF overtunity proggress.RSS.

Does 30kN only equate to 3t? I'm not an engineer, but I find it hard to believe that beam could only take 3t. Am I missing something?

This is great. But i have some question. In the table Specimen Compaction Data, I need to know where did you get the cross section, and i'm trying to compute 28.45 mpa but i couldn't have same answer. thanks

That is only cylinder compressive testing of the concrete alone, not the beam. As per australian standards. Target strength is 25MPa. The actual tested strength is 28.45 MPa for that cylinder.

yOU didnt wrote a yielding strength of reinforcing! Is it 500 Mpa or 400 Mpa. Because if it is 500 Mpa then this beam should take, according to EUROCODE, 45 kN of live load + self load before failure. I know that you did it according to Australian code, but i just say how it is according to eurocode. And please tell us a yielding strength od reinforcing.

I believe the machine would do both, just think about it for a sec.
