I would say obviously yes.
Take a step back from the code and just look at it from a public point of view. You are EOR and the loads that the building takes need to be taken into the ground, for that to happen it need to go through your foundation design.
From a business point of view, if this...
I see, I didn't notice the rotation. It makes sense now, would have been helpful to include a couple extra steps, but here they are for anyone else wondering in the future.
I have a arch steel beam very similar to the example attached from page 292 of 7th ed Textbook by Roark's ... The example says "To obtain the rotation of the arch at the point of attachment of the bar, we first calculate the loads on the portion to the right of the loading and then establish an...
Thank you for your suggestions! I spent some time reviewing the new material.
I couldn't find the books on Google or Amazon though:
- Bridge Engineering by David F. Merritt
- Design of Cable-Stayed Bridges by J. A. H. van der Meer
Looking to expand my knowledge, I have never designed bridges and am looking to learn. I am interested in the design and sizing of the cables that support the bridge.
Does anyone have textbooks, manuals, or resources with design examples for suspension bridges?
I have looked at the following...
Thank you, it all clicked once I read chapter 8. I was stuck for multiple days with this.
I would appreciate your work, but I'll post my file instead for anyone wondering in the future. And also post the snippet from the textbook chapter 8 explaining.
I put a simply "=if(" function at the...
I have a curved steel beam very similar to the example attached from page 300 of 7th ed Textbook by Roark's ...
My question is that the solution values don't make sense.
1. If you plug x=37.59 and x=130.9 into the Tx formula you don't get 13,100 in-lb & 8790in-lb respectively. (I get from...
1. 5000lb is the unfactored load.
2. That is in any direction in a 360 sphere, use engineering judgement to figure out the critical direction Shear, Bending, Axial Tension.
3. Eccentricity is whatever the height or length of the anchor. Where does the person attach to?
I have a follow up question:
Do precast mid landings and (in some cases) precast floor landings need to be rigidly connected to the core wall or placed to allow sliding deflection?
I agree if the stairs are rigidly attached to the landings and the landings are rigidly attached to the core walls...
Hire a lawyer.
I imagine the first thing that would happen when someone new steps into water is they fall over and (these being strapped to your feet I assume)would float up to the surface while the head sinks to the bottom.
And then they drown, that's where the lawyer comes in.
You can make your building heavier by:
1. Increasing depth of Raft slab or any other structural members
2. Use heavier denser aggregate in Raft slab.
Since this is a service case I don't think you can reduce H in any way.
DanielSgeo,
I_E: Importance Factor is not impacted by the SC it is dependent so on the type of building/purpose of building.
Like you said the SC does impact the Fa which you use to modify your Sa(0.2) to get your S(0.2). Sounds more complicated then it is, just take a look at section 4.1.8...
DanielSgeo, your question seems very straight forward to me, so here I go:
Simply put by designing a building in Site Class (SC) D vs F you are significantly reducing the horizontal seismic load that the building is designed for. I think you already knew that but your Sa(0.2, X_D)=0.446 vs...
mikek396 your calculations are probably right and the previous engineer is most likely being unconservative.
I find this type of construction related/temporary works has the most cowboy engineers around. That FS is the only reason that they get away with it. Probably due to the pressure from...
