Ussuri, Weighing will be the thing to do in this case.

E.g list the whole bunch of things he needs to do!

Mixtli, Help the guy out if you can that's what this forum is for. Advising him to go to a consultant because it is complicated maybe one answer, but if that were the answer for all the posts in this forum, it would cease to exist!

Dick, I agree you have to assume weights for design. My point is once the structure has been built you find that the weights are higher than assumed, can be a problem. Checks on tested densities and actual steel weights need to be carried out in case the assumptions were wrong. Particularly...

Thanks for replying guys! Dick, The calculation of the girder weight is simple and doesn't take long at all. You already know; 1. The theoretical volume. 2. The weight of the steel, strands, ducts etc.from supplier notes. 3. The tested concrete density. 4. The steel density. What if your...

Anyone agree then?

I agree with you guys also. The weight of the steel has to be deducted. if you work it this way, (without having to measure the beam) Steel is 7850kg/m^3 our tested dry density is 2430kg/m^3 Ratio of concrete to steel is 3.23. Theoretical volume is 20m^3 Steel is 8.9Tons Therefore...

I'm concerned the contractor is underestimating the beam weight. Some of the ancillaries are nearing their max Load. I'm looking for the best approach to get the weight of the beam. Caneit, thank you for your reply, your approach isn't very practical as it's a 30m beam of irregular shape which...

Here is what I have. The steel weight is known. This is from delivery tickets (fabricators slips)this isn't underestimated, its a heavily reinforced highway bridge beam 8.9Tons. The tested dry density is known and a little higher than normal OPC concrete 2430kg/m^3. The volume of the concrete...

I guess the issue is, we know placed volumes of concrete, and we know the theoretical volume. the placed values are 4m^3 more than the theoretical. (although this is fresh concrete volume and there is some evaporation et.) I guess taking the placed volume, you have the actual volume of concrete...

displaced volume? a known volume and the difference between..what exactly? displaced means you know the volume of a bath. although you fill it an what spills out is the displaced volume. so I don't think your getting this.

Hi there, I'm in a bit of a dilemma. Two arguments for the self weight of a beam. 1. to take a standard 2500kg/m^3 for the beam as (unit weight)which would include for the steel. for a beam with theoretical volume of 20m^3 so 2500*20/1000 = 50tons or 2. take the cylinder tested density of...
