h1 = 100 mm h2 = 500 mm B = 350 mm Tension steel, As = 6 of 28 mm diameter bars Compression steel, As’ = 4- 28 mm diameter bars Lateral ties = 12 mm diameter Clear concrete cover = 40 mm Concrete, f’c = 27 MPa Steel, fy (main bars) = 415 Mpa Steel, fyt (ties) = 275 Mpa 1. Determine the minimum spacing “a”, (mm)? (Use kN, use NSCP 2010 provision, the answer must be two (2) decimal places, and avoid rounding off when it's not a final answer) 2. Determine the nominal shear strength (kN) provided by the concrete? (Use kN, use NSCP 2010 provision, the answer must be two (2) decimal places, and avoid rounding off when it's not a final answer) 3. Determine the nominal shear strength if the lateral ties area is spaced at 125 mm on center? (Use kN, use NSCP 2010 provision, the answer must be two (2) decimal places, and avoid rounding off when it's not a final answer)
ASAP, round off the final answer to 3 decimla places

STRUCTURAL ANALYSIS II The given plan below shows a 2-way floor system carried by 1-story 2-bays frame system as shown in sec 1-1. The floor is 18 cm in thickness and made with reinforced concrete with fc'= 28MPA and fy= 420MPA, yc= 24kN/m3. The floor is to carry a service live load of 5 kN/m2. Assume that E is constant for all structural elements in the system. Determine the following: 1- Extract he structural system of beam ADG, beam BEH, frame ABC, and frame DEF, showing the loads to be carried on each element from the slab, and include the own weight of the element given that beams ADG and BEH have a section of 180mm in depth and 400 mm in width. Where the girder of all frames has a cross section of 300 mm in depth and 800mm in width. 2- Analyze beam ADG using slope- deflection equations method. 3- Analyze beam BEH using moment distribution method. 4- Analyze frame ABC using moment distribution method.
