What are stiffners ( Steel Structures) ?
What are stiffners( steel Structures)
Stiffners are secondary plates or elements which are attached to beam Web or flange to help prevent OUT OF PLANE DEFORMATION( I.E LOCAL BUCKLING).
Stiffners also serve to connect secondary beams to the main beam.
We have two types of stiffners based on how they are attached to the web of the beam, transverse and longitudinal stiffners.

Buying a Car V/s Hire a Cab
Buying a Car
V/s
Hire a Cab :
A Superb Analysis
Any Car in India cost at least Rs. 6,00,000
Scrap value after six-year - Rs. 1,00,000
The net amount goes in effective Life of six-year Rs. 5,00,000
Nos of Days of six yr is 2200 Days
So Rs. 5,00,000/2200
= Rs. 230/Day* Hire a Cab*

Buying a Car :
A Superb Analysis
Any Car in india Cost Atleast Rs 6,00,000
Scrap value after six year - Rs. 1,00,000
Net amount goes in effective Life of six year Rs. 5,00,000
Nos of Days of Six yr is 2200 days
So Rs. 5,00,000/2200
= Rs. 230/day
Yearly Insurance Rs 15000 = Rs. 41/Day
Daily Petrol minimum
= Rs. 100/Day
After Every 3 Years Tyre & Battery Change Charge Rs 25,000 i.e. = Rs. 23/Day
Yearly maintenance of Car Rs. 9000 i.e = Rs. 25/day
Plus interest loss on Car buying amount @8%on Rs. 6,00,000 = Rs 131/Day
So after buying a New Car Daily Expenditure = Rs. 850/day.
⚖️
So friends until you pay Rs. 850 daily to hire a cab, you are effectively in gain traveling in Rental Car.
OLA/ UBER Now Available.
Above all, driving cars on the Indian roads is full of risk added with Mental tension/BP...
New hefty Traffic challans not included.
Can this be the Real Reason behind recession in the automobile industry?
HAVE YOUR SAY FRIENDS!!!!!!!

Why do we have to place footings at least "B" distance from each other?
Why do we have to place footings at least "B" distance from each other?
Let me rephrase, isolated footings designed independently have to be placed in such a way that an adequate gap is ensured. That adequate gap is "B", which is the larger size width of the two footings under consideration.
Following Boussinesq stress distribution under a point load one can see that the stress from one footing extends B/2 distance from the face of the footing. Meaning if two footings with B width are placed in such way that the clear distance from the two is less than B, then the stress at B/2 from the footings is the sum of stress from the two.
Can we place footings such that the clear spacing between the two is less than B? Or do we have to go for combined footings?
The answer to this question is
to verify that the summation of the stress from the two is less than the allowable bearing capacity of the soil. If indeed the summation of stress from the two is less than the allowable no need to go for combined footings.
.....if the summation of stress between the two footings is greater than the allowable, then combined footings become inevitable.
The structural or geotechnical engineers out there, do u check the stress overlap between your closely spaced footings or u just go " as far as it is isolated and isn't overlapping"?
