The K Truss is a slightly more complicated version of the Pratt Truss. It's main difference is that the vertical members have become shortened - improving it's resistance against buckling. It does however have similar pros and cons to the Pratt Truss and although it is not widely used, it is a strong design. One of it's main disadvantages is that the members don't always behaive as expected. A member may be in compression under one load scenario and in tension under another. This can mean the structure may not be able to be optimally designed - since
