The Spreadsheet V2016-3 is based on the methodology of AISC with additions for the combined strength. Capabilities include analysis of rigid footings/mats with up to 16 piers (load points), as well as the handling of uniaxial/biaxial eccentricities. Rectangular Spread Footing Analysis/Design.
This type of design is typically used in tilt-up or precast concrete wall connections.

The spreadsheet is protected but with no password required. The bearing stresses at the head of the anchor typically create sufficient outward pressure to generate substantial friction at the grout/concrete interface. The spreadsheet is designed to find the embedment strength in concrete for the required plate within certain concrete parameters. The design of headed grouted anchors generally follows the procedures for cast-in headed anchors, assuming that the governing failure mode is concrete breakout. "EMBEDPL2.xls" is a MS-Excel spreadsheet workbook for the analysis of (2) Headed Concrete Anchors, HCA, per ACI 318-08, Appendix D.

Sign up a free account per direction to gain full access. It's very powerful yet extremely easy to use. Features include auto-generation of calculations and graphics of each failure mode. Tests of headed-stud anchors loaded in shear, as used in precast concrete construction, are not prevalent in the literature. This demo design sheet covers all types of anchors design including newly added adhesive anchors per lastest ACI 318-11 Appendix D. This program was initiated in response to new provisions introduced in ACI 31802, which were based on an exten-sive database dominated by results of post-installed anchor tests. The calculation of supporting surface's area that is geometrically similar to and concentric with the loaded area is added.Ī set of Mathcad Worksheets I made to deal with anchors made of embedded studs.Īnchorage to Concrete ACI 318-11 Appendix D it can be used for any profile or BUS as it is not linked to profiles tables. it covers both cases (Large & Small) Eccentricity. With Bending Moment & Axial Compression as per ASD. This Excel Sheet designs Base Plates for I-Shape Steel Columns. The internal bolt of the Power-Bolt is removable and reusable in the same anchor sleeve making it suitable for applications such as mounting machinery which may need to be removed for service and for temporary applications such as heavy duty form work.AG Base Plate with Moment & Axial Compression As the anchor is being tightened, the compression ring will crush if necessary to tightly secure the fixture against the face of the base material. The Power-Bolt is also designed to draw the fixture into full bearing against the base material through the action of its flexible compression ring. The bolt and cone remain locked together which resists loosening under vibratory conditions. This action engages the base material deep in the anchor hole. Further turning causes the threaded bolt to advance into the threads of the expander cone, forcing its four sections outward. First, the cone is pulled into the large triple-tined expansion sleeve, developing a mid-level, compression force. Expansion occurs at two locations within the drilled hole. It is available with a finished hex head or flat head with a hex key insert and can be considered for use in concrete, block, brick, or stone.
The Power-Bolt anchor, is a heavy duty sleeve style, self-locking anchor which is vibration resistant and removable.
