    What is Redundant Truss?

    Hi,

    In simple words, If m> (2j – 3), where m= members, j= joints, then truss is called a redundant truss.

    When m<( 2j – 3), then truss is called a deficient truss.

     

    If the members in a frame are more than required for a perfect frame, then that frame called a redundant frame.

    Redundant truss is statically indeterminate. In a redundant truss, the number of members present in it are more than that required in a perfect truss. So, such trusses cannot be analysed by making the use of equilibrium equation alone. Thus, redundant truss are those additional members or supports which are not necessary for maintaining the equilibrium configuration.

    Here are some reasons for providing redundant members ;

    • For providing support if the applied loading is changed.
    • For increasing stability during construction.
    • For maintaining alignment of two members during construction.
    • For maintaining stability during loading.
    • Analysis is difficult but possible.

    Redundant Truss is a Truss in which the excess number of members that makes it impossible to determine all member forces by using the equilibrium equation set.

    In other terms, we can say that the m>2j-3.

    A redundant truss is nothing but a truss with a degree of redundancy. A truss having redundancy means that there is at least one member in excess to what it needed to be just determinate and unstable.

    In other words, any indeterminate truss is a redundant truss. There’s a common misconception that only the trusses having a member carrying zero axial force are redundant truss. But it’s not the case. Even if all members are load carrying, the truss can be a redundant truss if it is indeterminate.

    Redundant trusses are the only kind of truss you’ll see though. It’s because of the simple reason that redundant trusses give us a margin for error against local damage. Suppose if the truss were determinate. Of one of the members breaks, the whole truss will collapse. But if the degree of redundancy is one, any one member can be taken out without structural collapse.

    Redundant Truss:

    It is a truss that includes a maximum number of structural members more than the requirement.


    Using the equation of equilibrium, it is impossible to analyze.


    It is a statically indeterminate type of structure.


    Thank You.
