Question $1-85$ Marks

a$.$ You are required to calculate permanent actions for beams $AD,BE,EH$ and columns A$,$ B$,$ D and E at section $1$ and section $2($on top of foundation$)$ for the office building from figure $1.$

Beams and columns are made by concrete with a density of $2300k\frac{g}{m^3}$ and gravity acceleration is $g=9\mathrm{.}81\frac{m}{s^2}.$

Assume for this exercise that:

cross section for beams is $250500mm,$

cross section for columns is $500500mm,$

concrete floor height is $150$ mm $.$
