rWarren Jackson- Faswall Alt 005.jpg Page 1 Faswall Coei. 3 generic concrete screen grid wall system without any reinforcing,show that the failure mechanism of the shear wall is a typical diagonal shear cluck failure mode. See also the attached GAT[from Shelterworks outlining construction methods,job site quality control,also included are test data and information on block performance,shell strength, durability,Fire rating,weather proofing and insulation characteristics and freeze thaw resistance. The vertical strength of the wall is designed as 8 inch wall sections loading with 12 inches of tributary loading. See the attached sample. For higher loads and large point loads the cell widths may be adjusted by specifying different insulation thicknesses. This allows cells to range from the standard 5"to a full inches in 1 inch increments. If needed for very short wall segments or even higher vertical loads the"large"core block may be used. These blocks have the middle web cut out with a 20 inch wide cell and again can vary from 5 inch to 8 inch thick. The anchor bolts and ledger bolts are designed per ACI 318 appendix D. See the GTAI details. For ledger bolts the face shell of the ICE is cut out to provide a"corbel"type support for the bolt The standard is a three inch circle but by bolt load design I call out larger cut outs as required. Ledger bolts and beam seat hangers are aligned with vertical cells. The bolt design only uses the effective embed as measured not counting the face shell thickness. The Faswall design is conservative in their design and a wide variety of loading conditions may be accommodated by adjusting the concrete strength,reinforcing size and cell width. The design is typically based on concrete strength of 2500 psi and does not require concrete testing;special inspection for bar placement is required. The ACI design we follow is similar to the reinforcing for boundary elements for A"Special Reinforced Concrete shear wall"but with higher required design loads by using the lower R value. The end result is a conservative structural design but with enough strength yet also provide enough plasticity to withstand the design seismic forces to protect the people using the structure.
