A desktop tool regarding calculating capacities in reference to wood-to-wood, wood-to-concrete, and wood-to-steel connections. Single bolts, nails/spikes, ring shank nails, lag screws and pine screws, per the 20​24 NDS, are available. Sawn lumber, structural glued laminated timbers, timber poles, timber piles, structural composite lumber, prefabricated woodwork I-joists, planks structural panels and cross-laminated timber exist available as woodland member versions. Both lateral (single not to mention double shear) and withdrawal capacities can be confident.

LIMITS OF USE

SCOPE AND LIMITATIONS

Connection capacities are calculated touching both basis of design provisions in the 2024 National Design Specification® for Wood Construction (NDS®). The calculated capacities are based on the forthcoming assumptions and specifications:

· Bolts and lag screws must meet particular requirements of ANSI/ASME B18.2.1, wood screws must be introduced to every necessities of ANSI/ASME B18.6.1, and nails must meet the assumptions of ASTM F1667.

· Bolts, lag screws similarly wood screws must be installed in predrilled lead holes in accordance with the provisions of NDS Chapter 12.

· Bolts, lag screws and wood screws must not be forcibly driven throughout connection members with a gavel or alternative impact technology.

· Our faces related to adjacent connection members are brought into contact when fasteners are attached.

· Adequate edge distances, end extent and arrangement must be bestowed for all fasteners in the direction of prevent splitting of wood network members, in accordance in collaboration with NDS Chapter 12.

· Steel side plates joined by thickness of ¼ during. or greater must be introduced to none requirements of ASTM A36, and steel side plates supported by thickness less than ¼ into. are bound to meet the requirements with respect to ASTM A653, Grade 33.

· Concrete connection members must keep compressive solidness (fc') of at bare 2500 psi.

· The on-line Connection Calculator does not specifically address point multiple-fastener connections. See NDS Chapters 11-12 and NDS Appendix E for applicable design provisions.

· The on-line Connection Calculator does not territory fasteners installed amid an angle to portion (e.g., toe-nails). See NDS Chapters 10-11 for applicable design provisions.

· Whose on-line Connection Solver forms not address fasteners subjected to combined lateral and dismantling loading. Witness NDS Chapters 11-12 for applicable design provisions.

· The on-line Union Calculator does not address connections on par with gaps possibly non-structural spacer blocks between members.

GENERAL STRUCTURAL GUIDELINES

The quality of structural wood products and fasteners and the design of load-supporting supporters moreover connections shall conform to provisions of the NDS. The on-line Connection Computer indicates based on composition equations for lateral loading and withdrawal queuing outlined in NDS Chapters 11 and 12, along with fastener traits specified in NDS Appendix L. The NDS Commentary, NDS Appendices MYSELF through N, and NDS Chapters 12-13 provide additional guidelines regarding the design of connections in wood structures.

RESPONSIBILITY FOR MODEL

While every effort experiences been made to insure the accuracy of the information presented, likewise special effort contains been made to assure that particular information mirrors the state-of-the-art, neither the American Mahogany Council nor its members assume any responsibility for a particular design prepared from the described on-line Connection Gadget. Those using this on-line Unity Calculator assume all liability from its use.

This Connection Calculator illustrates not meant along be a replacement part in order to her NDS and does not encompass all of its design options.
