Exauple 80 one story builsding is design to have lour main folumns For that has the Modeles if Elastaity of 20 MPa and the levegth of teis Columns \( 2.75 \mathrm{~m} \) Where the squre section of \( .3 \mathrm{~m} \) the effciabe maes of Me slabs Was \( 1900 \mathrm{~kg} \) and eyuvahe dapily ratio is \( £ 0.05 \) (1) Find the lumped Parametrs? (2) Optain the equation of mrtion? (3) Fine the Natrual Rrequay wn? (4) Find the damp hrequncy wo? (5) Find the damping Cofficent \( C \) ? \[ q=\frac{c}{a_{r}} \quad \omega_{n}=\sqrt{\frac{x}{m}} \] \[ k=E A / L \]
