Thanks for all the responses so far. Grizzman, I might just increase the thickness of the lower columns so that the splice detail is simpler; or, go for HSS5x5 throughout.
It's just that there are close to 170 columns to deal with.
I'm not a big advocate of "stiffening" the beam over the...
These are columns to be spaced at 10 ft o/c - with W10x15 framing to each side. I'm planning to splice the HSS6x6 ±18" above the floor. (it's all within the wall composition.)
I'm designing a column to be fitted for a four-storey building. The ground & 2nd floor will be HSS 6x6, while the last two floors will be HSS 4x4.
Are there visual examples that can be used as detailing for the splicing connection of these two different size columns?
I've worked with various ICF manufacturers that included my floor system... C-Floor Systems Inc. This US and Canadian patented floor system uses 'composite-action' technology that is simple and economical.
Only C-Floor® - by means of the Bond Bar – provides code complying concrete to steel...
My mistake to inform you properly... the purlins are modified to allow composite bonding to ±3½ -4" of concrete. The whole of the purlin is exposed! The rusting on the purlins is what the client wants to eliminate.
C-Floor Systems is comparable to Canam's Hambro... except, we use purlins...
C-Floor Systems is a new composite-action structural floor system using cold-formed steel. One particular client wanted "black" steel to be exposed. Now, naturally, the steel is showing signs of rusting. Is there any advice that anyone can recommend for my client to minimize (or even...
I'd like to think of it this way:
The difference between a Mechanical Engineer and a Structural Engineer is as such that once the Mechanical Engineer is finished with his design and it DOESN'T move... he's in trouble; while, with the Structural Engineer, once he is finished with his design and...
I would like to design a bollard (and its sonotube footing)to behave as a guardrail in a parking lot... essentially, for a horizontal force of 5kips @ 2 ft above ground. I'm using a 6"OD pipe embedded into a 24" sonotube (4.5 ft deep in the ground).
Is there a code for bollards, or using...
JAE, thanks for the quick and informative response. Typically, would the wood baseplate be in the 1" thickness or less?
In your opinion, what would be the consequenses should the contractor (or previous engineer) NOT recommend/install this wood blocker? Do you think that this negligence is...
Hello
Pleae, excuse my ignorance, but can someone explain (diagrams would help) the construction aspect of "setting the column baseplate on top of wood blocking"? Would not the column load "crush" the wood and/or once the wood disintegrates (being biodegradable) cause the steel column to settle...
I want to sincerely thank Ron & pba for their input... it meant a lot to me. With my new patented floor system using composite-action I thought of minimizing welding by replacing it with "easily drilled" screws. I found that even with Hilti, that the shear capacities for their best screw is...
Can anyone direct me to a website containing shear capacities of self-tapping screws for a shear load ±13kips (58KN) joining a 12Ga with 1/8 steel plate?
Second question: if I were to use these screws as a means for fastening rather than welding for full composite action shear connection...
Using Limit State Design (or other) how doe you arrive the quadratic equation to determine the exact location og the N.A. (ie center of gravity) for a typical 100mm (4") concrete overlying on a C10x3½x0.105 (12Ga) purlin?
bc(x2)/2 = n As (tc + ds - x)
I believe that an I-beam is what is called today a S-shape beam... that is narrowed flange, and a H-beam is what is called today a W-shape beam... a wider flanged beam.
It was readily common to distinguish the two by its name.
