But what about the effective depth? Should this be then d=95?īelow is a little sketch of typical wall, here the slenderness isn't too much, but that's not the point. I'm planning using vertical reinforcement in the middle of the wall with a spacing of ~400 mm - how to calculate this section? I would probably look at it like concrete section with a width of 1000 mm and two D12 B500B bars as reinforcement. Example calculation: If you input 100 concrete blocks, each with 2 cores, and you need 0.1 cubic feet of material to fill each core, the calculator will estimate that you will need approximately 2 cubic feet of. Should I take the compressive strength here as 18 MPa (design strength would then be fd=18/1,5=12 MPa?). The calculator estimates the total volume of material needed to fill the cinder blocks. The hollow blocks have characteristic compressive strength of 18 MPa, the concrete that they are filled with is probably C30/37 which has fk=30 MPa. They are 190 mm thick and filled with conrete.

There is significant variation in fill space among different blocks. The calculated volume of core fill (in cubic meters) will be displayed in the Volume (m) field. To use the Block Wall Calculator, simply enter the height and length of the wall, click on whether you are filling an 8-inch or 12-inch wall, then click on the Calculate button.The calculator will estimate the number of cubic yards that will be required. Click the Calculate button to perform the calculation. The walls are all only vertically loaded. Enter the length (in meters), width (in meters), and height (in meters) of the core fill area in the respective input fields below.

I'm designing a building that has a lot of masonry walls that are just a bit too slender to go without vertical reinforcement, according to Eurocode 6 at least.
