Instructions to frame_matrix

1. Instructions on how to use the MATLAB code(frame_matrix.m)
MATLAB code to carry out the Structural Analysis of a 2-D continuous beam.
Output includes Member end actions, restrained end reactions,
deflection/rotation
of free ends and support settling and/or support yielding can also be taken into
account.
A sample input is given in the beginning of the "frame_matrix.m", which is for
the case of
a continuous beam with 3 joints, and (EI) value changes between first two nodes,
at the mid-point.
The {AJ} and {AE} matrices can be defined as per the loadings given. The sample
input should give
an idea of the format of the input.
The case of support settlement or support yielding can also be accounted for by
editing the {DR}
matrix in the code manually.
Instructions on how to use the MATLAB code(frame_matrix_with Rotation.m)
This is a modified version of the earlier code. It is applicable for in general
any plane frame
structure and can also account for axial deformation apart from the already
mentioned featyres before.
Additional inputs such as "Cross-sectional area member wise" and "Moment of
inertia member wise" are needed.
