Simplify the rectangular & continuous footing design with StruCalc
StruCalc’s footing design module is very useful to create the design of square, rectangular and/or continuous footings.
The footing module can be used to meet size and reinforcement requirements for any concrete footing loaded with pure vertical load. Once a footing type is set, StruCalc will then require what is providing the load; it signifies that the type of column is set for the square or rectangular footing, or the stemwall type for the continuous footing.
As soon as the footing type is provided, then the loads on the footing should be entered. The loads originate from two sources: calculations somewhere in the structure that might leads to reactions from beams, columns, walls, etc., or they might originate from the use of the load calculator. The load calculator will produce loads on the footing depending on the user set floor, roof, and wall loads accompanied by indicating tributary widths or areas.
Just fill in the load options of the calculator and it will automatically workout the Live Load and Dead Load.
As soon as the loads are provided, there exist some supplementary footing/environment information like steel yield strength, concrete compressive strength, soil bearing pressure, reinforcement cover, and reinforcement bar size etc. should have been entered.
StruCalc preloads some common values for the properties stated above, but the user will be able to modify any values that seem to be inappropriate.
Besides, adequate information concerning the column should also be entered while going to perform a square or rectangular footing design.
Now, for creating the designing of a square or rectangular footing, StruCalc will need a depth and a trial footing width (and length for rectangular footing) to be entered. Once, these are entered, StruCalc will check their capability provide the necessary reinforcement.
If the dimensions of the footing are not sufficient, a red bar will be visible in the lower right hand corner of the screen and new dimensions should have to enter. It will be at this point though, that StruCalc will have computed a necessary area for the footing. It will facilitate the user to indicate dimensions to fulfill the required area.
While going to design a continuous footing, then the density of the stemwall and height, along with the footing depth should have been entered. Once they are entered, StruCalc will produce a necessary footing width and the continuous reinforcement that is essential.
