If an earthquake occurs with a predominate period of $0\mathrm{.}6sec,$ the building $($with reinforced concrete moment resisting system and $16\mathrm{.}6m$ height$)$ has possibility of being in resonance with the earthquake.

Unconfined reinforced rectangular concrete beam with following parameters:

$\frac{d}{d^{\text{'}}}=0\mathrm{.}1,f_y=276$MPa,$E_s=200000MP,f_c^{\text{'}}=34\mathrm{.}5MP{a}_{,},lo{n}_c=0\mathrm{.}004,p=0\mathrm{.}01,\frac{{}^{\text{'}}}{}=0\mathrm{.}75,$ the

curvature ductility is greater than $5$ and less than $10.$

$3.$ A $30-$storey building has a total height of $100m$ above the ground level. There are two such blocks to be built adjacent to each other. The storey drifts in each block is within $0\mathrm{.}4\%.$ The response reduction factor was considered as $8\mathrm{.}0$ and $Cd=5\mathrm{.}5.$ The minimum clear gap between these two blocks from earthquake considerations should be greater than $4m.$

$4.$ For building with moment$-$resisting reinforced concrete frames and height $22ft,$if the fundemantal natural period is $0\mathrm{.}6sec$ from eigenvalue analysis and $S{D}_1>0\mathrm{.}4,$ the distribution exponent $k$ is equal $1\mathrm{.}05.$

$5.$ The column members of a one$-$story building are loaded as shown in the following illustration. The allawable drift is limited to $0\mathrm{.}5\%$ of the height. The magnitude of the secondary moment is $13460N.$
