6"x16" hollow claytile weight
(OP)
This is my second question of the day regarding 1961 construction. I am looking at some existing concrete joists infilled with 6"x16" hollow clay tiles. Google search was not helpful and we don't have older books in our library. So if you know the weight, could you please share it here with me!
Thank you.
Thank you.

Weight of 6" deep flat tile: 26 PSF
Weight of 6" deep segmental tile: 30 PSF
My current scanning project for www.SlideRuleEra.net is the 524 page, 1934 Carnegie Pocket Companion (better have a BIG pocket

Take a look and see if this is what you have encountered.
Also, you may want to peruse the website, thanks to the contributions of numerous Engineering Tips members you can download your own fairly significant library of older technical references.

You may be looking at a floor system that is used with a thin concrete topping to create a composite system that is amazingly rigid with less deflection but still weighs as much. - It has been used for decades in many areas (with local dimensions and configurations) and the filler block have been clay tile, concrete block, AAC and even wood fiber/shred blocks.
Beams were set quickly with little special equipment, the special shaped fillers placed and the topped with concrete and the beams supports removed in a day or so.
The system is commonly referred to a structural floor filler system.

In my case, they are providing 16"x42" duct opening in between the joists. Both openings are near each end of the joist which is about 17' clear span. I have determined that the joists are OK in bending but a little over in shear so I am recommending reinforcing the joists with a steel angle for shear only. The angle is connected into the beams at each end and intermittently into the side of the joist.

I would like to see the drawings of the system and where (country) the construction is located.
There are many different systems world-wide, but generally, they are European influenced and different filler materials depend on local materials (AAC, clay tile, lightweight concrete, wood products, etc.) and the shapes and sizes of the filler vary widely to match the locally prestressed beams/joists sizes and configurations. Usually, the beams are set and then temporarily supported before the fillers are placed and the concrete is placed to insure composite construction. The shoring is removed quite soon (2 days to 14 days later) depending on the structure. In most international applications, the engineers have more direct control over the actual construction than in the U.S.
Openings are a problem since the most successful systems are used in areas where the conduits, heating pipes are cast into the system or in the integral 2" topping to create an 8" nominal floor thickness (beams/joists are 150 usually mm deep).
