Calculate trusses.

Static System. Most truss structures are designed with hinge connections, mainly due to 2 reasons:. Easier to calculate: Trusses with hinge connections make the structure statically determinate, which means that the internal forces can be calculated by hand.

In the virtual work method, the truss is analysed for the axial forces due to the externally applied load. Subsequently, the external forces are removed and replaced with a unit virtual load at the node where the ...Step 2: Balance Forces in the X Direction. Now you treat the entire truss as one body and balance all of the external forces, making sure they balance to zero in both directions. Start with the x direction: As seen in the picture, you define anything pointing to the right as positive in our equations.

Suppose the base of the actual roof is measured to be 40 feet. You can set up the following equivalence: base of triangle/base of actual roof = hypotenuse of triangle/hypotenuse of roof. Plugging in the numbers, you get 1/40 = 1.06 /x, where x is the required rafter length. Solving for x, you get x = (40) ( 1.06) = 42.4 feet.Faux wood trusses are a great addition to any space with vaulted ceilings.
