- An essential 5-story facility structure is conceptualized with an intermediate reinforced concrete moment frame. It is located on a site in zone 4 with a soil profile type Sp. The site is situated 13 kilometers from a potential seismic source type A. The story heights are 5.4 m at the ground floor and 4.3 m for the the 2nd and 5th floors. The story dead loads are 7600 kN from the bottom up. The plan dimensions are 55 m by 37m. The moment frames consist of two four bay frames in the transverse direction and two seven bay frames in the longitudinal direction. Determine the following: 18) Story shear at 4th floor 5.732 kN 5,261 KN 5,439 kN 5.814 kNarrow_forwardPlease show detailed solution: The office building has interior columns spaced 5 m apart in perpendicular directions.

- Tank is rigidly bolted to a foundation at grade. The weight of the tank when full is 444,820 N. It is located at seismic zone 4. Assume sufficient free board exists at this tank. The proximity of the tank to seismic source type B is estimated to be 10 km. Assume the fundamental period of tank is 0.05 sec. Based on NSCP 2015 Requirements, determine the lateral force on tank II.arrow_forwardDetermine the magnitude of the factored point load assuming the dead load = 150psf and live load = 60psf Answer from: 100kip, 110kip, 276kip, 400kiparrow_forwardA 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 total lateral force at the deck level in kN? Use Soil Type A. A. 357kN B. 314kN C. 354 kN D. 349 kNarrow_forward
