⭐️Frames:-
It may be defined as a structure,made up of several bars,riveted or welded together.
These are made up of angle irons or channel sections,& are called members of the Frame or Framed Structure.
🔥Types of Frames:-
👉Perfect Frame.
👉Imperfect Frame.
🔶Perfect Frame:-
It is made up of members just sufficient to keep it in Equilibrium,when loaded without any change in its shape.
The number of members,in a perfect frame may also be expressed by the relation:-
n = (2j - 3)
Where,
n= No. of members.
j= No. of joints.
🔷Imperfect Frame:-
An imperfect Frame is that which
does not satisfy the equation,
n = (2j -3)
Or,in the other words,it is a frame in which the no. of members are
more or less than (2j - 3).
🛑The imperfect frames may be further classified into following two types:-
👉⚡️Deficienct Frame:-
It is an imperfect frame,in which the no. of members are
LESS than (2j -3).
👉⚡️Redundant Frame:-
It is an imperfect frame,in which the no. of members are
MORE than (2j -3).
