Hi all, I am on my third TI-85 and the display is failing :(. I looked at other TI models including the TI-83, TI-84 Plus C SE and TI-89 Titanium. I was able to emulate those models on my phone to see if I'd like them. I still prefer the TI-85, and really want something that does conversions...

Thank you Ron, -K

I am spec'ing a steel form deck. Do you know when it would be appropriate to use a vented deck (type CSV) versus non vented (type C)?

Thank you Ron, That was the type of info I was looking for. Would you mind sharing which state sent the letter so I can look at their laws? Ironically, our company is big on getting "the company" certified in every state to practice engineering and be a licensed contractor in every state in...

Thanks, I know Wisconsin's law, but we have went from a local, general contractor and have grown much larger, now recognized as a federal contractor doing work all over the country in many different states. I thought that maybe someone has run into this before, and at least could tell me what...

I am in the US, so I am concerned with US laws... sorry, I did not clarify my location. Let me know what country you are from if replying, so I know what is acceptable where.... thx

Hey Snorgy, What state do you work in and do you know if there is a specific state that it is illegal to use "engineer" in your title? In Wisconsin, it is illegal to use the term "professional engineer" without licensure. Thanks, -K

Hi, I am a licensed professional engineer (structural) that works for a Design Build firm. Our company managers have a habit of calling new project managers "Project Engineers". I have a problem with this, because the people they are titling as "Project Engineers" are new out of school with...

Hi all, Thank you for your responses. As a follow up, we contacted SJI and their response was "There are no set standards except that the erector is to utilize the bridging to assure that the joists are reasonably true and plumb." So, who is to determine what is reasonably true and plumb...

Hi all, I received an email today from a jobsite asking what the tolerances are for a joist bottom chord to be bowed 1" to 2" out of plane compared to the top chord. The bridging has already been installed. Has anyone else ever run into this? I would assume a joist is not designed to...

Hi, When calling out an intermittent weld, say 4"@12", does that mean there is 12" of space between 4" welds or are the welds @ 12" o.c.? Blogett's book notes that the 12" is the "distance between centers" which I would think means the 4" weld is 12" o.c. I have a set of drawings that calls...

Thanks Mike, FYI, for others new at crane support design, I have some research results. American Crane, http://www.americancrane.com/, has cut sheets on their website for different crane sizes and gives maximum wheel loads, wheel base, bridge weight, trolley weight and trolley speed. American...

Nevermind, I messed with it a bit yesterday, and just realized it was a macro enable thing. Well, since the topic is started, do you have any additional advice for designing a building with a medium/light crane (7.5 ton) besides the AISC design guide? Is there a resource with typical crane...

Hi, Does anyone have experience with this AISC crane beam design spreadsheet? It will not let me select a W shape plus Channel. Any idea why? Thank you, -K

Chuck up the $$, buy your own and stop complaining as if someone owes you good free coffee.

dougantholz, What is a frost block? I would go for anything that is less expensive than a full blown stoop with frost walls. Thank you!! -K

Hi, If you have a building in Seismic Design Category D, Special Reinforced Masonry Shear walls are required. Per ACI 530, "1.13.2.2.5 c)Shear reinforcement shall be anchored around vertical reinforcing with a standard hook." This makes me think that horizontal reinforcing needs to be via...

Structural EIT, I agree.... I had a project where we had a few wind only columns that were only welded on the web. They left them unbraced for the weekend during building erection (before the beams at the top were attached) and a high wind ripped the the column about 2'-0" from the base...

We're in Wisconsin.... we do stoops with frost walls so that doors opening out will not be blocked by a slab that has frost heaved.

Hi, In the north we design all of our exterior doors with stoops that have frostwalls and footings that extend 4'-0" below grade. We are preparing a design build proposal for a building in Oklahoma. How are stoops typically designed/built there? I am told that the frost depth is about 22" in...
