How to Work on Tributary Area and Load Calculation

Civil Engineering Tips

Tributary Area and Load Calculation Tutorial. In a civil engineering problem, it always necessary to calculate loads on each of the columns and beams, to know the strength of the structure. There may be structure having unsymmetrical dimensions resulting into uneven distribution of load. Learning how to calculate the load becomes a task.

The loads in those uneven structures are found by estimating the tributary areas for a particular beam and load. The video present here explains an example problem of determining distributed load on a beam and column reactions for a simple beam-and-plank system with unsymmetrical bay sizes.

Tributary area is the space or area that a beam or column is responsible for carrying on a floor. It is the area contributing to the load reaction on the respective beam or column. Using the dimensions given in the plan or drawing, the calculation of the tributary area becomes quite easy.

The video by John Tingerthal, here shows how the load of the floor is distributed among the beams and columns. Although the floor is unevenly distributed over beams and columns, the tributary area can be calculated and hence the load can be estimated. This is very useful for the construction professionals. Go through the video.
