Assignment $1$

A three$-$span five$-$story frame as shown in FIG. $1,$ the vertical load on each floor is shown in the figure. The line stiffness of each beam is $1.$ The line stiffnesses of the columns except the bottom columns are $0\mathrm{.}498,0\mathrm{.}448,0\mathrm{.}498$ and $0\mathrm{.}448$ from left to right at each layer. The line stiffnesses of all the four bottom columns are $0\mathrm{.}471.$ Try to obtain the bending diagram of the frame using the layered method.
