Thanks, I'll look into it.

Mike, The "long" corbel is point loaded. Thanks, I did manage to find professor Mattock's research on the PCI Journal website. Initially I just searched under the quarter for which his articles were referenced. Surprisingly for the years that i searched (1975 and 1976) only two quarters for...

Thanks Mike, I appreciate the information. Paul

What are the dimensional limitations for a "bearing ledge" along a wall and a corbel? Where are these limitations stated? In what code/section?

Its been quite a while since I started a thread in this forum. I forgot about the ACI Code Forum. Please see the following thread for my question that I posted earlier to the 'Structural engineering other technical topics forum;' thanks in advance, Paul thread507-302529

I am reviewing a structure designed to the ACI-71 code which states shear stirrups are required for corbels. A.h of stirrups is to be no less than 50% of primary tension steel area, A.s. The designer decided that since the shear could be carried by the concrete that stirrups would not be...

daylight211, your discipline is civil/environmental. if you do site design/utility/highway design/terrain modelling then yes 3d modeling will be most helpful (i.e.Autodesk, Eaglepoint). For other applications you will want to meet with your competitors/colleagues as your existing and...

Thanks metengr! Fortunately that is what the author used in his calculation. My next question(s) is how did you determine these values? based on ASTM A829?

metengr, Thanks for your input- I really do appreciate your assistance. In response to your last question if the BOM states ASTM A829 Grade 4340 ( for washer plate material) without any additional information - what would you expect the minimum yield and the minimum ultimate tensile...

metengr: What if it is not called out? What should be the default values?

Correction the BOM calls for ASTM A829 not 826.

ASTM A829 provides in Table 3 (Tensile Strength Ranges) the three potential "Specified Maximum Tensile Strengths" (up to 70 ksi, over 70 to 110 ksi and over 110 to 140 ksi) with the corresponding Tensile Stregth Range of 15, 20 and 25 ksi. ASTM A829 does not explicitly list for any of the 30...

metengr and gil1985: Where did you obtain the tensile and yield properties for this particular material and grade?

What are the minimum bend radii for stainless 18 gage and 3/16" sheet steels?

Thank you for your time and expertise, I sincerely appreciate your efforts. :>)

The current owners work during the day. If we purchase the house, there will be someone home during the day.

I have a few questions regarding the use of heat pumps in northern homes. My wife and I are currently interested in purchasing a house that has approximately 2000 SF living space and is a multi-story/split level arrangement. The curious thing about this home is that it used to have a gas...

The Lincoln Electric publication "The Procedure Handbook of Arc Welding" also states that the minimum tensile strength for AWS Classification for E308L weld metal is 75 KSI (as referenced from the AWS A5.4-69). AWS A5.4-92 also lists the strength at 75 KSI.

DaveAtkins, I have checked the stresses in the tube wall through use of the procedure in the AWS D1.1 for punching shear. Stresses are reasonably low. What my concern is are there any other issues (that I have not addressed in my initial post) that would negatively impact the joint connection...

Thank you JStephen and Lutfi for your consideration, the C6 is to be welded to the TS to form a "TEE", i.e. two members at 90 degrees. Stating the match-up of the 6" dimensions was to indicate that the flanges of the channel are to be even with the top (or short sides) of the TS6x3.
