What power shovel is doing there?
Is there any soil settlement-like situation occurred before starting a collapse; in front left side column area? so the lateral loads introduced into the frame and bow in floor can be seen there.
and obviously as (Agent666) mentioned , "So a big stack of...
Thanks JStephen3 & KootK for your valued comments!
My fabricator having a good stock of 40NB Pipe Material; which make us to think of utilizing those material somewhere else for a relatively unimportant Temporary Hoarding type Structure. Horizontal loads mainly wind are supported by the...
Any one has literature or information on design of structural members made out of group of pipes?... i.e. bundled pipe column and beams.
How they behave under compression or bending?
How will be the connection look like between two different bundled beam and column?
Anyone has any idea or...
I feel, they have introduced this Constant to established relation between Yield strength and Ductility of the steel.
Is there any literature available for derivation of Epsilon value?
Cheers! -VH
Hi friends,
As per BS 5950; the parameter (E) "Epsilon" =(275/Py)0.5 is used for Limiting width to thickness ratio for sections in Table 11. (where Py= Yield Strength of the Matl)
My questions:
01. Why does the Epsilon value get reduced for Higher Yield Matl/steel?
02. Can any one throw some...
Is there any possibility to bring fixity at ends to the said beam by providing Top & Bottom Flange Splice plates?
May be you find it a economical way to reduce deflection. (Another Whacky alternative...)
Note: The Supporting Beams's capacity need to be validated for these addition moments...
I doubt,if Etab/any software (based on stiffness matrix) could distribute the auto lateral seismic force accurately between floors; though it can handle multiple towers in one file.
Nonethelessly; you can ve some useful information regarding the topic at below site...

"How can I check local buckling?"
-----------------------
Since plate is not subjected to any kind of point load or non-uniform loading; I don't see any local buckling problem in a plate. It seems that you are interested to know the deflection of the plate under uniform pressure loading...
Based on the requirements (i.e. acceptance criteria, pros and cons of weld flaws/imperfections, type of weld, thickness of plates, recordkeeping of test results, cost and time schedule etc ) one has to take a call for appropriate NDT method.
UT and RT have their distinct advantages and the...

If you are using Staadpro; Section wizard tool may find helpful to you.
can easily calculate elastic and plastic section properties of custom and built-up shapes.

Slender section elements :
"Then it will be considered as slender section element and designed that way. Isn't it?" - Agreed (code will guide you)
THIN section elements :
"These structures may land in deep trouble with long-term durability problem after a time, mainly in highly corrosive and...
"building serviceability" - here I mean Long term durability of the structure.
The only reason I asked first you to check min. plate thickness to be used for your structure as per code which you referring.
Cheers! -VH
As your basic query is about welding - refer the welding Bible - "AWS" welding code.
I hope everybody has attempted your welding query here.
Though the main objective of PEB structure to optimise the steel weight; I also feel web and flange plates are too slender as per your rules of thumb...
While earthquakes the sloshing effect of liquid on the side wall creates additional horizontal forces which need to be considered.
Basically idea is; Impulsive mass of liquid acts on the lower part of the tank and convective mass of liquid on the upper part. During seismic event; the mass of...
