this is as per column position concentric and as per eccentricity produced by moments it is eccentric . when columns are provided at the boundary or or in the center of footing many of us consider as eccentric... many desgners combine this to nearby footing or provide strap beam
Excellent! The two triangles that you have to calculate Mx & My. one of the triangle is not right angle and the result mathematically is not correct. You could use trapezoidal area = {(sum of parallel sides)x height}/2. Thank you !
Hi bro...In continuous beam when we remove ( Moment distribution method) ...the moment that comes on support span or column point that are Moment x direction or y direction ( Mux 1 and Muy 1)
Could you please mark the direction of your X-Axis, and Y-Axis on the plan because it is shown your Mx is take about Y-Axis and My is about X-Axis ? Very confusing. Thank you !
This is concentric footing. We provide eccentric footings when we don't have enough space on at least one side of footing in site. Here, using the size whatever require as per bearing capacity.
Why in determining size of the ftg u dont used the 2.82? Why for checking for size u add and minus Both direction x and y? And for pressure diagram u add and minus M/z in each direction?
Pressure diagram is only showing what shall happen in one direction and how to calculate for single direction. But as we have to find Maximum Pressure, the column footing will undergo. And thus "Moment in x and y" both directions will play role in actual loading condition that too at the same time along with "Axial Load". So Pmax = (Axial Force/Area)+(Moment Mx/Section Modulus Zx)+(Moment My/Section Modulus Zy)
@@anand4236 I donot have the link , however I know how one should proceed to get approx results, but I would recommend a finite element software to get pressure checks, shear checks and bending moment value.
Best civils educational video I've watched! Keep up the good work!
DESIGN OF CORNER FOOTINGS BE ALSO UPGRADED. NICELY EXPLAINED
Grand super analysis and expln by this brilliant strl engr voice is another God given asset

Design property line footings like isolated edge footings & corner footings .
This is not eccentric footing,its a concentric footing.
Eccentricity here is converted to moments

Cg changes
Good ... . What if the column is to one side of the footing like footing size is 2.4 x 2.1 column is at the edge of the footing at any side.
could you share the textbook or any references about this topic it will be helpful to me
Thanks
So nice explanation
Can u design Edge footing .or shoe footing
Awesome
Madam How can calculate Muz and Muy which are shown in Given data.
Pls provide flat slab design
@cwill Structures
When Footing Size is square, What is the formula of qmax and qmin?
Is the any basis of considering D = 2 to 3 times of Dx?
And, Dx should be = 500-50-12-12/2 m?
How to find mux and muy value when we calculate manually
czcams.com/video/Bc9DYHzvfQo/video.html
how on any corner of footing two different values of stresses is possible?
there must be only one stress at a corner? please explain..
For calculating MX, Please explain how did you get 115.25kN/m2 pressure at column face?
Mam how can i find moments on columns of a framed structure
Hi bro...In continuous beam when we remove ( Moment distribution method) ...the moment that comes on support span or column point that are Moment x direction or y direction ( Mux 1 and Muy 1)
there are no such text books i have
seen . but there is a hand book by ranathunge from sree lanka .

ok, to keep the size, but we can't keep equal offsets from column and design will be different

NICE EXPLANATION 3 DIM ABOUT ,
Mam please do the design of strap beam footing
shoe footing is just like you leg and foot . draw free body diagram .you can apply the same principle
How do you get pressure of 115 .(11.34)
SAME QUESTION
Can I provide sq.footing for rectangular column
Please share .... strip footing
SBC'S BE ALSO MODIFIED AS PER IS 456
Why factored load not considering
Next part please
it's uploaded only. You can find link in description box.
Why pmin should be greater than zero?
pmax / pmin < = 4 !!??
But this is concentric footing right?
In 11:25 from where we get that value of 115.25, please anybody can explain me
interpolation of pressures
This footing is not eccentric since the colum is right at the centre of footing..
How did you calculate the 115.25 kn/m2
by linear interpolation
@taha ali= pmin +((pmax+pmin)/L)×l
@taha ali L= total length
l= length (which u will be decided for calculation)
please do proper research before calculating the moments, the values which you have taken are wrong.
Do you have any video for eccentric footing.. If you have please send the link..
