Excellent. As an electrical engineer I have been struggling with how to approach a beam loading problem for 3,500 Lb transformers and this give a great intuitive overview as well as a nice step-by-step approach.

This is just a phenomenal explanation and walkthru. I started with your video and had to double back a couple of times to some texts on line to figure out the reasoning behind why certain calculations were coming out the way they were, but once I did it just all fell into place intuitively and your video was smooth. Well done.

Depends on what you are trying to do. To get the load on a column, you can use tributary width of beams and girders X their lengths to get the point loads to apply to the column, or you can get the same number directly by using the tributary area.

@mugdav6699 4 жыл бұрын

Why do we have to multiply live load with tributary width of the beam not the tributary area when determining the load acting on the beam

@mugdav6699 4 жыл бұрын

And why don't you multiply the plf with the length of the beam when determining the load on the beam

There are very good information.- I wish to calculate the moment of a rectangle who is supported in only one side.- This side is supported by a shaft.- The shaft will rotate 90 degree in order to move the rectangle who has a distributed load of 100 pounds.- Which is the torque on the shaft?.- This is which could be the max torque in the shaft from zero to 120 degree?

can you reply to this: if you have a continuous beam setup,do you analyze the beam first as continuous beam and get the shear forces at various supports and add up the shear forces to give the total support reaction at every point or do you assume the beam is simply supported between the supports and just divide the beam loads into two to every supports?

@Loppy2345 6 жыл бұрын

Good video, but what about the continuity factor? Or are beams taken to be pinned at each column connection?

For example in a double storey building, Does the beam in first floor sustain whatever load (max shear force) carried by roof beam other than the weight of slab and wall?

@JohnTingerthal 9 жыл бұрын

You Xian Hang No. The first floor beams and girders only take load from the first floor (unless there is a column from 2nd floor that does not continue to the ground. 2nd floor load travels down the columns directly to the foundation.

How would you calculate the loads on a 2x6 stud wall just right under a roof?

@JohnTingerthal 10 жыл бұрын

Load on top of the wall would be a line load, same as on one of the beams. The load in each 2x6 depends on the spacing. For instance, if the line load at the top of the wall is 300 plf and the studs are spaced at 16" o.c., then each stud takes 300 plf * 16"/(12"/ft) = 400 lbs.

if we go multi-storey, does the tributary area adds up for the determination of column size or does it remains same?

@JohnTingerthal 9 жыл бұрын

kalpana gupta yes, for the columns. Each lower column collects additional load from each floor. Visualize load like water and the columns as pipes. By the time you get to the bottom, the pipes (columns) have to collect all the water (load). Each floor, however is independent.

@000000001992 9 жыл бұрын

So, while designing the dimensions of the column, the tributary area of the column would be ( in basic terms) the area supported on one floor multiplied by(times) the number of floor. Am i right?

May i ask why do we need add the beam load when we are calculated FORCE ACTED ON BEAM ?

@willhaa3378 7 жыл бұрын

I'm no engineer , but IMHO is that the beam itself contributes to the load placed on it ... i.e. ... its weight is being supported by what? Itself.

@Ajvb219 4 жыл бұрын

He’s is trying to calculate load on column not beam. In order to calculate total load on column, you must include the beam weight itself and anything bearing on it

Where did the deck loads come from? Those must be known values.

@abdiwalihussein3466 7 жыл бұрын

how are they known bro? from code?

@monicapttrsn 6 жыл бұрын

The International Residential Code (Table 301.5) specifies a minimum deck live load of 40 psf. If you add in appx. 10 psf dead load, that equals 50 psf. Where did 68 psf come from? You've heard of residential deck failures because of young adults swarming the deck for parties, and then they collapse. So, it would be wise to design a deck with a load of something greater than 50 psf, in case guests attempt to treat the deck like a commercial building instead of a residence.

This is based on the assumption that the beams are simply supported.

I dread videos explaining through the imperial system of measurement 😩. Otherwise this is a beautiful engineering concept of load distribution and support whose final stability ultimately depends on the bearing capacity of the compacted soil beneath
