1. What will be summation of entire individual floor lateral seismic load?
The figure above shown is an incomplete diagram of a hospital consisting of reinforced concrete frames with rigid joints. Given that S_DS = 1.2g and S_DI = 0.5 g and w= 400k.

$What will be summation of entire individual floor lateral seismic load?The figure above shown is an incomplete diagram of a hospital consisting of reinforced concrete frames with rigid joints. Given that SDS = 1.2g and SDI = 0.5 g and w= 400k.\r\n$

4V 3V 2V V

V

On summing all term of equation used in above question, e will see that y cancel out each or and only term v remains. Also, analytically sum of forces on each level should be equal to net seismic force/load.

Hint Answer

2. Impact load results from which type of effects of loads applied?

Static Dynamic Static and dynamic Neither static nor dynamic

Dynamic

For static load, impact effects are short lived.

Hint Answer

3. What will be velocity pressure at a height of 80ft. if k₈₀ = 0.5, k_80t = 1.2, k_d = 1.3, V = 120mph and I = 1.67?

45.019 46.019 47.019 48.019

48.019

q_z = 0.00256 k_z k_zt k_d v²I, where q_z is wind pressure at height z.

Hint Answer

65.59

F_x= (W_x h_x^k V)/(?w_i h_i^k). Here, x = 4 and value of denominator term is 2714.735. Also, V has already been calculated in above questions.

Hint Answer

6. Which type of drainage system will collect rainwater?

Primary Secondary Tertiary Primary and tertiary

Primary

Primary system will collect rainwater through surface drains on roof and direct it to storm sewers.

Hint Answer

7. How does an increase in pitch of roof affects amount of load that can be placed on it?

It increases It decreases Remains constant Depends upon case

It decreases

As rise increases w.r.t span, load carrying capacity decreases.

Hint Answer

8. Dead load comprises of:-

Permanently attached loads Temporarily attached loads Permanent as well as temporary loads Snow load

Permanently attached loads

They include weight of structural frame and that of walls, roofs etc.

Hint Answer

9. What will be flow rate (in gallons per minute) if A is 10 ft² and rainfall intensity is 2 inches per hour?

0.208 0.0208 2.08 20.8

0.208

Q = 0.0104Ai, where I is intensity of rainfall in inches per hour.

Hint Answer

10. What will be minimum value of total static lateral base shear for a hospital id S_DS = 0.15g?

.0079gw .0089gw .0099gw .0109gw

.0099gw

V_min. = 0.044S_DS IW hospitals have an importance factor of 1.5.
