Theoretical analysis and finite element analysis (FEA) are two main. The typical flanges used for vacuum vessels are flat-faced, with metal-to-metal contact outside the bolt circle, (because self-energizing elastomeric O-rings are used for sealing as opposed to the compression type used for raised-face flanges). 3-14 Appendix D ACI 349-06 CSA-A23. Interaction of Shear and Tension for Bolts Traditional analysis methods only cover the interaction effects of shear on the shank of the fastener and tension alone on the threaded portion. Cyclone Outlet so that the flange with bolt holes is on the build plate Cyclone Inlet so that the flange with bolt holes is on the build plate Air Ramp so that it was flat on the build plate BUT because I used a heated bed I IMMEDIATELY removed it and while it was still warm pulled it into the helix shape that you require. For now, the only product that we commercialize and support is our web application composed by many modules (material database, bolted flange design, saddle support design, lifting lug design and so on). 0 AMERICAN INSTITUTE OF STEEL CONSTRUCTION iii PREFACE The primary objective of these design examples is to provide illustrations of the use of the 2010 AISC Specification for Structural Steel Buildings (ANSI/AISC 360-10) and the 14th Edition of the AISC Steel Construction Manual.
