2. Wood–Armer method - Wikipedia

   en.wikipedia.org/wiki/Wood–Armer_method

   The Wood–Armer method is a structural analysis method based on finite element analysis used to design the reinforcement for concrete slabs. [1] This method provides simple equations to design a concrete slab based on the output from a finite element analysis software.

3. Welded wire mesh - Wikipedia

   en.wikipedia.org/wiki/Welded_wire_mesh

   This type of mesh is a square grid of uniformly placed wires, welded at all intersections, and meeting the requirements of ASTM A185 and A497 or other standards. [1] The sizes are specified by combining the spacing, in inches or mm, and the wire cross section area in hundredths of square inches or mm2.

4. Reinforced concrete - Wikipedia

   en.wikipedia.org/wiki/Reinforced_concrete

   Concrete spalling from the ceiling of an office unit (interior) in Singapore, possibly due to rebar corrosion. Reinforced concrete can fail due to inadequate strength, leading to mechanical failure, or due to a reduction in its durability. Corrosion and freeze/thaw cycles may damage poorly designed or constructed reinforced concrete.

5. Reinforcement in concrete 3D printing - Wikipedia

   en.wikipedia.org/wiki/Reinforcement_in_concrete...

   The welded wire meshes are laid in-between printed layers of slabs without requiring any formwork. They can also be used to print wall elements that are fabricated laterally and erected in place. In a method unlike with rebars, spools of meshes are unwound simultaneously ahead of the printer nozzle to provide both horizontal and vertical ...

   To 15-7Φ5, for example, 5 said a single diameter 5.0mm of steel, 7Φ5 said seven of the steel wire to form a strand, and 15 that the diameter of each strand of 15mm, the total meaning is "one The beam consists of 7 strands of diameter 15 mm (each having a total diameter of about 15.24 mm, a dimensional deviation +0.40 -0.20; a diameter of ...

8. Concrete slab - Wikipedia

   en.wikipedia.org/wiki/Concrete_slab

   A corrugated slab is designed when the concrete is poured into a corrugated steel tray, more commonly called decking. This steel tray improves strength of the slab, and prevents the slab from bending under its own weight. The corrugations run in one direction only. A ribbed slab gives considerably more strength in one direction. This is ...

9. Precast concrete lifting anchor system - Wikipedia

   en.wikipedia.org/wiki/Precast_concrete_lifting...

   As the orientation of the void determines the lift position of the lifting clutch, the wire chair can be secured against the element reinforcement to maintain this orientation during the concrete pour and set. When an anchors load resistance must consider load reduction factors, this would imply that the particular selected anchor will form a ...
