Yes I did. Thanks. But, what I don't necessarily agree with is designing the plate to resist bending without considering the contribution of the flange. The plate and the flange will act like a T section. I found an example somewhat similar to this in Blodgett on page 3.3-25 and 3.3-26. The...
Does anyone have a design methodology or can anyone point me to a design guide for the design of partial-depth web and flange stiffeners according to the 2010 Edition of the AISC Steel Code section J10? I cannot find any guidance on how to design these elements anywhere. The description of the...
If you don't use control joints, for a slab on form deck, would you use ACI minimum temperature and shrinkage (T&S) steel requiremente (rho=0.0018) for reinforcement perpendicular to the main flexural reinforcement? Or would you place welded wire fabric (WWF)? Our slab is total 8" thick with...
We have an elevated concrete slab on form deck in a large industrial building. How often do you space the control joints? How often do you space the expansion joints? Where do you locate the control and expansion joints? I imagine that the location of the joints will differ with the orientation...
We have a large piece of mechanical equipment that is self supporting and weighs approximately 300k. The manufacturer did not supply seismic loads. We did the superstructure design but not the foundation design. We need to supply the foundation engineers with the seismic loads. Which chapter in...
Call Vulcraft and they will send you a derivation and a design example. I don't have mine here at the office or I would scan it for you. They will also help you with the calculation.
I am designing the support structure for a circular storage bin that is 54 ft. in diameter and 100 feet tall. Which provision in ASCE 7-05 should be used to calculate the wind load on the bin: Section 6.5.12.2.1 Rigid Buildings of All Heights (using Kd=0.95); or 6.5.15 Design of Wind Loads on...
Wrought iron is made by flattening of a piece of iron and folding it over and repeating the process to remove the slag. It wasn't very efficient. In Newman's book "Structural Renovation of Buildings," he states welding to wrought iron is prblematic and he references "Field Welding to Existing...
ASCE 7 is tying to confuse you. They make the definitions of partially enclosed and open so you can calculate them. They give three categories. If your structure is not partially enclosed or open by calculation (not by what you see), then it is enclosed. The structure is considered enclosed even...
271828,
I agree with you that both LRFD and ASD shouldn't be taught. It would take too much time and other topics would not be covered. It would only serve to confuse the students. It would be like teaching Spanish and Italian in the same class and then ask the students to have a conversation...
JAE,
I didn't call you a fool. I called the act of removing ASD from the Steel Design Manual foolish. Please read my post more carefully.
271828,
Please change your name to something catchy!!! I can't remember all of the numbers. I have crawled out from under tree or out of the gutter depending...
Bliman,
Right on! Not only have most professors never designed, they've never been to a jobsite. Even with inspectors there, the structure will not be built as designed. Put fat into it! Going onto a jobsite will put the fear of God in you.
