I am stumped on this eccentric load on weld group. Say you have a flat bar welded to a table and the bar cantilevers out like a diving board. This is a weld group in bending correct? If so can I use fb = Pe c/I ? (similar as laid out in this guide...
I see 15th edition is only $288 (new) on amazon now.. I think it was quite a bit more than that last time I checked. I figure that will be the best investment going ahead especially looking long term like Lomarandil said.
I see the 15th edition came out, is there any reason not to go and buy it? I heard there may be alot of errata? I am not a structural engineer, I work for a contractor and use the manual once in a while.
Sorry if this question has been asked a lot but I did a search and did not find a recent...
What does or where did the subscript "a" come from for required strength in ASD design? As in Ma, Ra, Pa, etc.
Shouldn't it be called "r" instead or something so people don't confused it with "allowable"?
Hi. I have a very simple and maybe dumb question, but how do you interpret blow count N-value when there is a wide range in the blow count?
For example I am reading a boring report with N-values range from 18 to 50 blows which ranges from medium to dense. Can I just take the average and use...
I am checking the lateral load capacity of an existing brick wall. Shear is straight forward but how do I calculate the horizontal bending capacity?
ACI 530 states that fb = calculated compression stress in masonry due to flexure only, psi
Is the tensile strength of mortar to brick so low...
Thanks for the replies! Okiryu and PEinc, there is no soil under the two upper slabs/other side of wall. The walls are attached at top and bottom. It is a small area which will have a dirt ramp to run a small excavator on. Not sure what the height of the soil will be at the moment.
Please see sketch below. Is this a case where at-rest lateral earth pressure should be considered? The area between two existing walls is to be infilled to allow for some equipment to be driven over. I'm sure this question has been asked before but I've done a bit research and still am not clear...
I'm looking to design a fall arrest anchor in reinforced CMU wall using a swivel "d-ring": http://www.fallprotectionpros.com/guardian-mega-swivel-anchor-steel.html?gclid=CLLR69bPytQCFROBswodsecK9A
It is not specified to be used in CMU. However, we are looking to use it in a reinforced CMU wall...
What is with this large variance in bending strength of Spruce-pine-fir. One table is from nelma.org Northeastern lumber manfacturering and the other is from the 2005 NDS.
Is there a standard/base bending strength/rule of thumb for bending strength of lumber? On alot of drawings I just see...
How can I find the maximum allowable point load for hollow core plank load applied with a through bolt similar to the image attached? Assuming 8" thick 5,000 PSI slab, 10 ft long span.
The hollow core plank manual (...
Thanks for the responses!
I will lower the spacing to 24".
How do I calculate the maximum moment on the wales when there is a non-uniform load? In this case the lateral pressure of the concrete. I can't figure out the load (w) is for Mmax=(wL^2)/10
I have to check the following concrete formwork layout. It is to be used for walls and footings. All the studs, braces and wales are 2x4's and the sheathing is 3/4" plywood. I have checked the wales and studs for bending and the braces for compression and they seem okay but I can't figure out...
Hi everyone,
I work for a construction company and have my PE license but have never stamped any drawings. I have very limited design experience. Recently my boss asked me start stamping some small construction related design drawings such as temporary formwork (for concrete) and fall hazard...
