    Shear strength of concrete

    Shear plane perpendicular to panel. Ie for Wind loading. This is not for flexural reinforcement, this is simply a connection to hold the panel from in and out movement, the connection is in plane shear on the concrete and bending of the dowel.

    Shear strength of concrete

    Thank you Koot, that is what I assumed but didn't have an authority stating that it would be fairly negligible. Signious, if the concrete shear strength is sufficient then there is no need to ensure that the yield strength is reached as the shear will govern. Also shear reinforcement is only...

    Shear strength of concrete

    The shear strength of concrete (Canada) is given by the formula: Vc = 0.2 x λ x ᶲc x √f'c x bw x d Where λ = 1 for normal weight concrete ᶲc = 0.6 f'c = compressive strength of concrete bw = width d = depth Suppose we have a dowel (say rebar) in the center of a concrete...

    Strength of stainless steel welds

    Thanks TD & Al, Yes, I found out about D1.6, this is the reference I need, just having trouble finding a site where I am able to view it online.

    Strength of stainless steel welds

    Thank you, TDIengineer But what are the electrodes to specify to match 304? Also can I use the steel tables and just factor in fy for stainless as compared to mild steel? I do know that stainless yield curve is different than steel. I'm looking at the code for the Euro zone that someone...

    Strength of stainless steel welds

    I searched quickly and couldn't find the shear resistances for different size of welds in stainless steel. Could someone direct me where I could find this information? I'm in Canada, so something from North America would be best. Thanks, Greg I've seen this, on pg 23, but this limits the...

    Torsion of a T section

    dhenger, The lathe below would provide enough support to keep the tiles from moving, that is until frost eventually breaks this bond. The joints are also caulked except on the right side of the section allowing excess water to drain into the gutter. Ground or poured concrete is below on the...

    Torsion of a T section

    I've already informed them that they need to go 12" spacing. (for the 24" long slabs they want to use) They currently use the condition where there is a continuous stainless steel sheet under the entire assembly and wanted to cut the costs of such a system. I'm not quiting and will continue to...

    Torsion of a T section

    Well this is just a job I'm doing on the side for a friend, she's with the company. I wouldn't work long for a company that doesn't work with you, even if the details you are coming up with are more economical and durable than theirs. For instance, there really is no need to insist on stainless...

    Torsion of a T section

    Great idea BA, but I do not have any power to make those kind of changes and the detail is a standard detail. I already suggested to use 1'-6" or 2'-0" width slabs and this would not be an issue, however the company wants/insists to have the design like this.

    Torsion of a T section

    Thank you so much hokie66! You and the rest really helped me on something I didn't know much about. So if there is no need to check for torsion, all I need to check is the rotation of the section?

    Torsion of a T section

    Like I mentioned, all the steel is Stainless. Second any profile or section needs to be fabricated, and since it is stainless and the company has basically no options for suppliers to fabricate an HSS would be a very expensive proposition. @ Hokie, Yes the granite is embedded into the lathe...

    Torsion of a T section

    I thought the detail is fairly basic. I don't see how it can really be simplified.

    Torsion of a T section

    Yes, BA and Excel you are both correct the maximum stress is at the joint.

    Torsion of a T section

    This is the detail.http://files.engineering.com/getfile.aspx?folder=27de1042-542b-4d94-afcb-e322e621dd05&file=Gutter_Detail_June_5.pdf

    Torsion of a T section

    The application is: - support of granite slabs over a pool gutter drain - stainless steel plates are being used to fabricate a section - therefore, I wish to minimize the plate sectional area as well as the amount of welding required - An HSS would be ideal, but the costs would be prohibitive...

    Torsion of a T section

    Btw, I'd like to increase the strength without increasing the thickness of the section, if this is possible.

    Torsion of a T section

    I'd like to first get confirmation of a torsion question. 1) The shear center is located at the intersection of the flange and web. So if the load is applied at the end of the flange the torque is load x flange width/2? 2) The maximum shear stress is located at a point most distant from the...
