Edge margins - minimum 1½ (fastener dia) preferred 2 (fastener dia) Countersunk head Edge margins - minimum 2 (fastener dia) preferred 2½ (fastener dia)" and e is the edge distance measured from the hole centre to the edge of the material in the direction of applied stress." Minimum spacing of the SDS for sawn lumber applications is 3" o.c., minimum end distance is 3", and minimum edge distance is 5/8". The depth of the hole can be deeper or equal to the minimum embedment depth of 2" which is equal to the length of the anchor . I only have very minimal axial loads on the brace. The values in Tables 2, 3, and 4 are based on a minimum spacing between the center of fasteners of three times the diameter of the screws, and a minimum distance from the center of a fastener to the edge of any connected part of … The primary change to the 2015 NDS is incorporation of design provisions for CLT. This whitepaper examines common DVE challenges and some promising solutions. In this white paper learn how a standards-based, systematic, and automated generative MDD/XIL workflow helps automotive engineers develop their production ECU Verification & Validation (V&V) suites early during software modeling, and reuse them throughout the overall systems engineering project. *Eng-Tips's functionality depends on members receiving e-mail.
