- Steel Beam Penetrations (Sizes and detail?) 1 - Eng-Tips
I am running into a problem in the field where beam penetrations through my steel beams need to occur Our detail shows that the depth of the penetration can be D 3 (D = depth of steel beam) and the length of the penetration is 3 4*D This rectangular penetration has fillet welded plate top, bottom, and sides
- General contact problems - Eng-Tips
Perhaps your penetration is too big to be removed with default settings Please take a look for following chapters in Abaqus documentation: 34 4 4 Controlling initial contact status for general contact in Abaqus Explicit
- Roof Penetration detail through Metal Roof | Eng-Tips
Penetration-Free Attachment A first rule about any rooftop mounting is to do it without penetrating the roof membrane whenever possible While this may seem obvious, on metal roofs, it is often violated The norm for attaching things seems to be: "anchor to structure through the roof "
- D1. 1 Partial Pen vs. Complete Pen question | Eng-Tips
No a partial penetration weld is not a sufficient alternative, for the full penetration weld As you noted the 1 8" land would is expected to provide an area of incomplete fusion This loss of area and the reduced design strength would provide a weld insufficient to develop the full strength of the material thickness
- contact of elements not initially touching | Eng-Tips
The point is initial gaps are not 'forced' to close, and that reactions on the contact area only occur if penetration is calculated Just to reiterate the answer, for a press fit dowel or initially gap that may close on load, use frictionless (or rough) contact, with pure penalty formulation
- Fire Smoke Damper for Shaft Enclosure | Eng-Tips
In fire scenario, outside fresh air may be prevented to go into the room, that is why damper is necessary to block the outside air penetration If the duct you mentioned was exhaust duct, standarts can be read again and find appropriate solution but it is fresh air duct and there is no exception for that in IBC (International Building Code)
- determining pipe penetration type | Eng-Tips
In my understanding, a sleeved bulkhead penetration would allow leakage between compartments and may or may not be acceptable in some areas The type of piping penetration depends on the compartment requirements as well as the engineering requirements of the piping system ( most importantly, the piping system temperature)
- Drilled piers and load testing | Eng-Tips
We are going to require the owner to hire a geotech engineer after the contract is awarded to verify our design Anyway, I am looking at the spec, and there is several sections relating to testing, including a Load test, Penetration test, and a Proof Test Hole
