QUESTION $1($Total $19$ marks$)$

You are required to calculate permanent actions for the structure presented in figure $1,$ for columns $A,B$ and $E,$ at the elevation corresponding to section $1$ and section $2$ of the building.

Beams and columns are made by concrete with a density of $2400k\frac{g}{m^3}.$

Assume for this exercise that:

cross section for beams is $250500mm$ including slab,

cross section for columns is $450450mm,$

concrete slab height is $200mm,$

gravitational acceleration $g=9\mathrm{.}81\frac{m}{s^2}.$
