I have double-pitch roof beams spanning 24 m,
the rise from support to apex being 0.5 m.
Each beam is designed for ultimate moments due
to wind loads and factored dead loads, and a
permissible service load deflection of L/250.
The owner has attached a suspended ceiling to
the roof purlins. As...
The first paragraph in a white paper titled "Analysis of Simply Supported Beams" states:
'A solid grasp of simply-supported beams is one of the cornerstones of an engineer's education. This is even more important when the analysis is done by computer. To know and understand the...
I had a heart-stopping experience many years ago. My brief was to be the structural engineer under an architect to install new floors in a six-story city building. The documentation made it clear - in the usual manner - that the builder was responsible for stability and wind resistance during...
This kind of task is easily solved with MATHSERV
http://www.engs-comp.com/mathserv/index.html
For example, type in any word processor:
A = {1,3,6,8,4}
B = {5,6,2,3,9}
C = mattranspose(B)
D = matmult(A,C)
print using "####"; D
(this command returns a 5x5 matrix)
5 6 2 3 9...
Hi, irulandi
You say:
"In Masonary works we have used solid blocks, yesterdat i found in one wall is cracked in 5m lenght and width is 5to6mm.
That wall construction was over by before two months (inculding plastering) now POP applying activity in progress.
...can i go ahed for painting...
Hi, fagg1
1. Live load for car parks is 3 kPa unless vehicles of more than 2.5 t tare are involved, in which case it is 5 kPa.
2. At 60m x 60m, temperature effects can be ignored except in the roof slab.
3. 60m x 60m is not too big.
Additionally, you should consider impact loads amd breaking...
PHEW - this post takes some time to read.
But it's worth the time - so many good thoughts.
1. Do your own manual checks.
2. Don't trust SS unless you know what they do.
3. Why don't you share your hardwon knowledge?
etc.
I agree with most of what's been said,
having practised it myself for...
I have "Excel 4 for Scientist and Engineers". It has helped me a lot to program in Excel. Of course, there are probably later versions. If you go to:

you might find exactly what you are looking for.

What bothers me about the question "I am looking for a good software" is that it implies the user will rely on the output of the software without knowing how it was produced, and without some means of checking whether the output is in the right ball park.
To me, this philosophy is...
I agree with earlier comment that "Foundation Analysis and Design" by Joseph E. Bowles is excellent.
If you want to see some cue cards based on this book, have alook at:

Unfortunately, I haven't yet got around to the retaining walls section, but it...
I have a computer program called OPT_SHED, which designs all elements of a portal frame building on the basis of cost-effectiveness.
After the program determined the wind loads from your site information, it lets you choose a cladding from many alternatives - a dearer cladding requiring fewer...
I like your philosophy, Imagineer - "design the column as if it was pinned and design the baseplate, etc. as if it were fixed" - hang the client's money.
That's what clients think we do, anyway. And if something goes wrong when we are less conservative, who gets blamed?
Good on you...
One Australian standard that has a bearing on this question is AS 1684.1 - 1999 - Residential Timber Framed Construction: Design Criteria
For RAFTERS Live loads this code states that concentrated loads and partial area loads may be factored in accordance with AS 1720.1, assuming the crossing...
Dear Pylko
I have spent a few years as a pile driving contractor, after inventing a machine that could drive recycled railway lines. Forget your Geotech's 8 tonne per square foot - it is irrelevant to driven pile capacity. The H pile sockets into the rock until the driving resistance equals...
