I modeled a 5x5 tubular column as plates. I'd like to change it to a 6x6. Is there a fast way to do this without having to change each and every node? Theres alot of nodes...
Hi all,
Realize this has been discussed before, I reviewed the threads and can't seem to find a clear answer to this question.
In the case where one has a base plate supported by anchor bolts and leveling nuts lets say the assembly is sitting on an 18" thick footing. Anchor bolts are...
I've got a RISA 3d model built up. Used plates, its a pretty simple little support I probably missing something simple.
All the forces are in the X direction, vertical axis is the Z axis.
I have what is basically a column sitting on a plate with 4 pin nodes. I was expecting to see equal (or...
Hello all,
I've got a 12' retaining wall that I'm working on for a subdevelopment. There will be sidewalk right next to it along with curb and gutter and then a road.
For H20 loading at a 6' distance if one goes through the California Trench and Shore manual, analysis as point loads comes out...
I'm attempting to wrap up my design on a drilled shaft in an SDC D design area.
Its a 48" diameter shaft pretty much everything is done aside from fishing through Ch 21...I'm finding this section a little difficult to interpret so I want to make sure I'm doing it correctly.
For background...
Think I posted this in the wrong forum the first time...maybe someone here has some comments?
I had a question regarding the placement of some questionable concrete.
I was on a jobsite in the middle of a slough where the contractor was placing a pedestal that sits on top of a pile cap...
Hello all,
I had a question regarding the placement of some questionable concrete.
I was on a jobsite in the middle of a slough where the contractor was placing a pedestal that sits on top of a pile cap.
The concrete mix was delivered on site around 11:00. The specs stated the slump was...
Hello all,
I'm working on running the numbers on nothing more complicated than a fence. I'm trying to figure out, using the asce method II what to do for the gust effect factor. Its not really a building, I would say its more like a flexible structure described in 6.5.8.2
In looking at the...
I'm also looking for a good structural text on how to design drilled piers. Anyone have a recommendation? A course would be nice too.
There seems to be lots of geotechnical information on them but very little as far as structural design goes.
Thanks,
Will
I am working on a small project using hydroCAD in the Maple Valley, WA area. The city apprears to have adopted the KCC stormwater design manual.
According to the KCC manual, the design method to be used for an area under 10 acres where the runoff is not detained is the rational method...
I've been asked to compare the strengths of a couple different sections, without the use of loads. (consider it to be flexural failure)
I seem to recall a procedure that was used way back when I took mechanics of materials.
I have the sizes of the steel and the wood member. To ballpark it...
I'm new to using HydroCAD. I have the site modeled, I would like to include the pipe inside the trench for additional storage, but I'm having a hard time getting HydroCAD to do it.
I'm running version 8 so I already have all the downloads from http://www.hydrocad.net/exfilt.htm the outer...
Can anyone recommend a good book with examples of structural design of large pad footings and or slab on grade foundations?
The book needs to have design examples, not some 200 page book with all sorts of professor like wine and cheese text blathering on about the finer points of soil...
I have a project where the designer wants to use polycarbonate roofing. I have not used this as structural sheathing before.
Anyone used this for gravity and lateral load transfer, if so is there a good icc-es report or something similar so I know what the properties are?
I am looking at...
Can someone tell me where to find values for application of gypsum over plywood? Know this is commonly done for fire protection, can't find the table or line in the IBC for the reduction.
Have a similar situation where I was hoping to use these values.
Thanks
Does anyone have or know where I can get my hands on a Bowman Catalog? I have a contractor who wants to re-use the hangers but I can't find any values for them.
Thanks
Does anyone have some testing values for the situation where 22 gage steel walls are used instead of standard walls?
I have a pole building I am working on where they chose to sheath the walls with this stuff.
I remember seeing some values at the other firm I was working for in an old manual...
Per IBC 2305.3.7.1 allows for alteration of shearwall design by a "rational analysis". (Actual engineering!) I would consider the shear transfer mechanisms to be the wall top plates, to the top window sill with blocking full length across the segmented wall providing nailing for a coil strap...
