Answer:
Step-by-step explanation:
The stairway's waist slab is 210 mm thick. 15 mm and 10 mm clear cover
The primary steel utilized is diameter bars. If so, M is its effective depth.
A 230 mm 0
A 190 mm 1
A 200 mm 0
A 180 mm 0
Retaining walls are utilized to M
A Rock 0
A Planet 1
A Steel 0
An actual 0
At zero, there are contraction joints spaced 7.5 meters apart.
shear in M's water tank
Rigid joint 0 in A
Joint A of a roof slab
Joint between a vertical wall and a base, A
The incline joint is A.
187.33 mm2 is the size of the main steel utilized in the slab. what does 8 space mean?
diameter of the bar if the effective slab depth is 143 mm M
A 350 mm 0
A 267 mm 1
A 415 mm 0
A 518 mm 0
Loss if Frictional Stress Depends on M
Concrete's elasticity modulus is zero.
Friction coefficient A 1
A Steel Relaxation 0
Slip 0 in Anchorage
Q One oscillation or natural period of vibration requires M seconds of time.
A 2π/ωn 1
