Have them cut on the face on a number of the cells at the bottom of the wall to prove there is minimal droppings. If they find some then cut all cells with rebar. Is this partially grouted? Or go straight to check all the cells that have bar. What is your comfort level... at this point they bear...
Am I reading the NCEES website correct... 1,400 dollars in testing fees for an SE assuming you pass all test on the first round. 2,100 dollars if you end up retaking two sections. PE is 400 dollars. *Just to be facetious. Do SE earn 3 times more than a PE or is that ratio just hold for fees...
How are people handling substitution request for deck fastening to open web joists? Is the contractor/third party engineer requesting the substitution responsible for checking strength, stiffness, base material thickness and does this need to be sealed or should the EOR include this re-design...
For tall structures, IEBC has provisions on the height that get triggered. I think the height provisions are for non-structural stuff like egress. That's outside of this discussion.
I consider STAAD more of a general FEM software but has old design codes ie aluminum design code from the 1998 or not integrated very well into the design modules ie no masonry design or you need an external design process. The only design module that is decent is the STAAD to RAM connection...
I dont have the IEBC open but I thought there was a provision about changing the lateral system and about percent increase of the demand to capacity in any element. I think you changes would trigger those provisions.
Ditto as Josh. Definitely worth doing a quick gut check on the members and loads (no equipment) but I don't get heartburn using it for short, small maintenance access platforms.
cec17: I would put "short" and "maintenance" in the description of the platform as well.
EDIT: Looks like I was late...
What FEM software are you using? A few options are offset nodes or extend the slab past the nodes or hand calc the load and apply the load at the nodes as point load (line load if you are fancy and put in dummy beams).
The owner is paying you for your expertise. I would hope that they would value your judgement. Now I will get off my soap box, I would pose the following question if the members do not meet the AISC tolerances for straightness, etc. does it make sense to evaluate them using AISC methods or are...
What is the criticality of the equipment? Generally the best resource is the manufacturer. If is a "widget" as opposed to a "super scanning microscope" most design is done by experience.
A few rules of thumb for starting are braced frames are the best and get an example of a successful past...
Depending on the criticality you may consider testing the rock. WJE has an article related to stone durability below is an excerpt. Bring in an expert may be a good approach.
I think its just the terminology that is getting you hung up. In my sketch, he is calling x-axis the minor axis so using the right hand rule (putting your thumb in the direction of the axis) then bending about x-axis or the minor axis is the strong direction for the stud. Even as I write this it...
Sounds like you are in the messy middle of life. Its bitter sweet. A few things that proved helpful to me are learning more about personal finance and budgeting. The Money Guy show is a good resource and they nerdy take on personal finance appeals to my engineering brain...
My understanding is yes to both. It increases the stiffness and reduces fatigue cracking at the post to baseplate weld.
Also depends on the capacity of the crane. The stiffeners seem to be added at capacities over 1,000 lbs based on my observations.
One item I have seen in contracts is re-negotiation, there is some risk to this since the owner could cancel the contract on you. Put a clause that if metric (CPI or something) exceeds a certain value say 7% in a year then the contract is subject to re-negotiation. Or you can put a date in your...
The tax advantages are going to be specific to your situation so check with your CPA. Try googling "commercial rental income tax advantages" there are articles out there that give lists. The cost of entry is much lower with the residential houses that are converted to commercial. I assume that...
