Thanks Jed. Very helpful to hear advice from others. My question was really pertaining to the reinforcing requirements of ACI 350-06, 10.6.4.1. While using the severe exposure criteria gives that warm fuzzy feeling that helps one sleep at night my concern was mainly just about over designing...

ACI 350 provides criteria for Normal and Sever Environmental Exposure. I see the requirements for Normal exposure stated in Sections 2.1 and 10.6.4.5 to be liquids with a pH greater than 5, or exposure to sulfate solutions of 1000 ppm or less and Severe being anything exceeding Normal. Does...

Has anyone devised a clever way to enlarge the mesh size of a model? I inherited a model with a very small mesh that takes too long to run and I can't think of a way to "enlarge" the mesh without going through a pain staking process or reworking the model from scratch. Thanks in advance...

I'm reviewing a set of calcs for a precast vault in which the designer is using the shortcut formula to calculate the area of steel required in the walls. However instead of using the typical As=Mu/4d with factored loads he is using As=Mu/1.76d with unfactored loads. Where is the 1.76 coming...

Thanks for all of the input. Ronnie Measure twice, cut once.

I know this is not the best application but can anyone give me in short answer form if I can spec out a 3/4" X 9" stainless steel Nelson Stud to be welded to a 1/2" mild steel plate, in the field. Plate can also be 3/4" if that would help and stud could also be some other corrosive material but...

I have a question about concrete vaults. I found a precast concrete vault online that will meet my application however now we are making modifications like a knockout and adding a sump. Are large concrete vaults (8'x 10') typically purchased as an off the shelf precast item and modified as...

Thanks JedClampett

I understand exactly what I'm saying. Maybe just didn't express it clearly enough. I'll try again I am a civil engineer, EI but haven't had a chance to do very much structural engineering using the AISC code yet. I was basically looking for a refresher course, tutorial, some brief explanation...

Does anyone have any good tips or references I can use to help me learn how to use the AISC steel manuals to find basic member capacities? It seems a little difficult to decipher everything when you first pick it up. The text doesn't really explain how the tables work or what to look for...

Thanks dhengr. That's the same numbers that came up with. I found an AISC LFRD moment connection guide online to help refresh my memory.

Thanks Duwe6. I think I figured it out with a little Google help. I didn't know how to calculate the joint for both shear and moment.

Hi all. I need help understanding forces in a welded connection. I am welding the end of a W14x61 strut perpendicular to the flange of another W14x61 waler at the end to form a corner. This is a rectangular temporary retaining frame for an excavated pit so all joints are in compression and 4...

Yes. Background lets you set up a background just like going through the render panel but just renders it, doesn't record it.

No. Posted question on several CAD forums and no answer. I think everyone imports into Navisworks. I did see one trick that I still need to test out. Some guy on YouTube made a dome over his model to simulate a sky. Change color to light blue and it will work. I want to import pic of sky to...

I figured out how to record an animation of a walk through or fly by of my model but I can't get my background to come out right. All I get is a black background. Am I doing something wrong? Please help if you have any ideas. Thanks!! Ronnie
