Kinematic indeterminacy : Solve a simple problem you will get to know.

They are asking about a number of simultaneous equations that to be solved in SDM. It is equal to no of joints in the structure.

But in SDM, no of unknowns = Kinematic indeterminacy.

Answer should be 'Degree of Kinematic Indeterminacy'. Slope Deflection method is a kinematic method. The unknowns in this method are the unknown displacements or translations and unknown rotations at joints of any structure which is subjected to bending. Hence the number of simultaneous equations to be solved in the slope deflection method, is equal to degree of kinematic indeterminacy.

@Vinay.

It is no of joint rotation and not number of joints
In the non-sway frame, only rotation of joints considered as an unknown, which is nothing but the degree of kinematic indeterminacy.
In sway frame sway of frame i.e. horizontal displacement of the frame is additional unknown, which is also nothing but the additional degree of kinematic indeterminacy.

Option B is correct because No of equation required =Dk.

How is it please tell in the slope deflection we are not taking joints?

It depends upon Kinematic Indeterminacy.

Mohanraj said:   7 years ago
We can not form the equation at the fixed support (joint). So it will not depend on joints. It will depend on kinematic indeterminacy. We can form the equations at intermediate and simple joints only. Because there only kinematic indeterminacy is possible.

Slope deflection methods applied shear and joints.
