Sres sanjivani college of engineering kopargaon. This particular type of truss offers some interesting features mainly thanks to the fact that the vertical members provide tension while the diagonal ones are bringing in compression. I have used it often for my model bridges including balsa basswood and popsicle sticks.

In this fashion they form a pattern of interconnected ns. What makes it so good and gives it an advantage over the howe truss is how it spreads out the forces when under load. From above analysis and design of pratt truss following limit state method is more reliable and economical than the working stress method for designing roof trusses for the same configuration of truss total percentage saving in weight of steel is by limit state method is 23 as compare to working stress method. Often seen in bridges it features several vertical chords that are connected by a diagonal chord.

The pratt truss design as pictured above is one of my favorites. An alternative pratt truss is shown below right where the diagonal members are in tension for uplift loads. Pratt truss this is one of the most popular steel roof truss types and it is quite economical. Sppu pune page 1 unit no.
