Pls solve with FBD’s it’s imperative. Handwritten answers only. The building section associated with the floor plan in Figure P2.3 is shown in Figure P2.7. Assume a live load of 60 lb/ft on all three floors. Calculate the axial forces produced by the live load in column C2 in the third and first stories. Consider any live load reduction if permitted by the ASCE standard.

The time effect factor for load combination 1.2D + 1.6(L, or S or R) + (L or 0.5W) is 0.9 O 0.8 O 0.6 O 0,7

2. Using the tributary area method, compute the floor dead loads supported by columns A1 and B2 in Figure 1.2. The floor system consists of a 6-in.-thick reinforced concrete slab weighing 75 Ib/ft?. Allow 15 Ib/ft? for the weight of floor beams, utilities, and a ceiling suspended from the floor. The precast exterior wall supported by the perimeter beams weighs 600 lb/ft. 20 18 C.panel 9' 18 Epanel 10 10 11' ! 11 11'! 11 Epanel Epanel Epanel Figure 1.2

A floor slab 100 mm thick is cast monolithically with beams 250 mm wide 450 mm deep spaced 1.2 m on centers, on simple supports over a span of 5.0 m. The floor supports a service live load of 2.1 kPa. Using f.-21 MPa, rebar strength f, 415 MPa, calculate the following if a typical interior beam is reinforced with 3- 16-mm-dia. flexure bars at the bottom enclosed with 10-mm-dia. stirrups: 1.

A column in the upper story of a building is subjected to a compressive load from the followingsources: dead load = 30.8 kips, occupancy live load = 1.7 kips, roof live load = 18.7 kips, and snowload = 19.7 kips.a. If load and resistance factor design (LRFD) is used, determine the factored load (requiredstrength) to be used in the design of the column. Which ASCE load combination controls?b. What is the required design strength of the column?c. What is the required nominal strength of the column for a resistance factor phi of0.9?d. If allowable strength design (ASD), determine the required load capacity (requiredstrength) to be used in the design of the column. Which ASCE load combination controls.e. What is the required nominal strength of the column for a safety factor Omega of 1.67.
