Question

Transcribed Image Text:Given: bxh = 400 mm x 600 mm
Ast=8 x 32 mm diameter bars
Clear concrete cover to 12 mm diameter ties = 40 mm
Concrete fc' = 28 MPa
Steel fy = 415 MPa
400mm
Mu = -420 kN-m; Vu = 370 kN; Nu = 580 KN (Compression)
For WL to the -X direction:
600mm.
Reduction Factor for shear = 0.75
Due to reversal lateral force, the design axial load due to the combined effect of DL, LL and WL change are follows:
For WL to the +X direction:
Mu = +420 kN-m; Vu = -370 kN; Nu = -450 kN (Tension)
1. Ans. 220
Determine the concrete shear strength (kN) for the positive x direction of WL by simplified calculation.
2. Ans. 0
Determine the concrete shear strength (kN) for the negative x direction of WL by simplified calculation.
3. Ans. 125
Calculate the required spacing (mm) of shear reinforcement. Apply code provisions on spacing limits of reinforcement where applicable.
