      Warren Truss is similar to the combination of Howe and Pratt Truss. Maybe that is what you are looking for.

    the queen truss shown above are not according to the concept used in books but seems like scissors truss,why?……if it’s right, please rectify it.

      Hello Nawin,
      This is a typical queen’s truss. This is not a scissor’s truss and does not resemble a scissor’s truss in anyway. Scissor’s truss resembles an inverted V-shaped arch.

      You should research on Tubular roof trusses as well as North light roof trusses.
