Additional shear on frames $1-1$ and $4-43$ points due to earthquake shear in y$-$direction is given by

$V_{y1}^{\text{'}}=-(0-0\mathrm{.}25)V$;$V_{y4}^{\text{'}}=(0-0\mathrm{.}25)V$

$V_{y1}^{\text{'}}=(0-0\mathrm{.}25)V$;$V_{y4}^{\text{'}}=-(0-0\mathrm{.}25)V$

$V_{y1}^{\text{'}}=(0\mathrm{.}25-0\mathrm{.}5)V$;$V_{y4}^{\text{'}}=-(0\mathrm{.}25-0\mathrm{.}5)V$

$V_{y1}^{\text{'}}=-(0\mathrm{.}25-0\mathrm{.}5)V$;$V_{y4}^{\text{'}}=(0\mathrm{.}25-0\mathrm{.}5)V$
