Flat roof building are a popular architectural style in dry climates because of the economy of materials of construction. However,during the rainy season water may pool up on the roof decks so thag structural considerations for the added weight musf be taken into account if 15 cm of water accumulates on a 10m by 10m area during a heavt rain storm,determine (a) the total added weight from the standing water the building must support. (b) the force of the water on the roof in psi.

Solution
A 4-storey with Roof deck AFP armory is to be constructed in Sulu. The facility is essential for the housing of the Philippine Army's newly purchased weapons, ammunitions and explosives. The location of the facility is 7.5 km from the known source which is capable of producing a magnitude 6.7 earthquake. The structure is a Steel MRF with an overall height of 14m from the NGL. The weight per level of the slabs and stairs is equal to 1740 kN. For the walls at the typical levels, the weight is computed as 2362.5 kN and for the parapet at the roof deck level, the weight is computed as 388.8 kN. An equipment 2.0 meters high with a hexagonal cross - sectional area whose sides equal to 1 meter is installed at the second level and has a weight of 100 kPa. Using R = 8.5, which of the following most nearly gives the lateral force at the 4th level in kN? Use Soil Type A.
if we had dual system structure but we cant use dual system on the structure because does not satisfy point D or E.with out changing anything in the structure of the building we can use 1-bearing wall system or 2-Building frame system which is closer to the double system or which is considered more appropriate of the two (bearing wall system or Building frame system)? and why it is more appropriate???
Compute the maximum combined loads using the recommended ASDexpressions from the AISC. D = 10,000 lb,W = ;32,000 lb
Wind can produce very high drag loads on high-rise bulidings. Since calculating the áow around a buildingis quite diffcult, you decide to perform an experiment to find the drag on the nearly completed Mirabellabuilding at Univesity Drive and Myrtle Avenue in Tempe. The building is 250 ft tall and approximately 210ft wide (at its widest part) A) determine the drag on the Mirabella building for a sustained wind speed of 40 mph. Supposethat the temperature remains the same both inside and outside of the wind tunnel test section. If theatmospheric pressure is 100 kPa, what would the pressure have to be inside the tunnel test section tomaintain dynamic similarity between the model and the full-scale building? (You may assume that thetunnel is operating at maximum speed.

Design a two way slab using the Coefficient Method considering an interior panel (Case 2). The slab will carry retail storage from a commercial warehouse for service live load. The dimensions of the interior panel are 4.50 m x 5.50 m. Use 2015 NSCP Strength Design with f'c = 28 MPa and Fy = 276 MPa. Unit weight of concrete is 23.56 KN/cu m. Include simple structural details as part of your output at the end of your computations. Note: Refer to the NSCP for your live load.
