For an edge flat panel, given that Vu=160 k , slab thickness = 10 in, d = 9 in, fc'= 3000 psi , fy = 60000 psi, column dimensions 24 x 24 in . Answer the following questions : a- Is shear reinforcement required ? (show your calculations) b- Will shear reinforcement solve the problem ? (show your calculations) c- Determine the parameter required to resist the given ultimate shear load then find a . d- Determine the stirrups spacing S . e- Determine the number of stirrups .

Expert Solution

shear strength of requried=Vn

Vu = 160k

Vn= 160/0.75 = 213.33k

shear strength of concrete =Vc

compare Vc and Vn

VC < Vn as 23.6 < 213.33k

therefore shear reinforcement is required

Vs1 =Vn -Vc

assume 2 legs Av = 2 (,11) =0.22 in2

spacing of stirrup = s

use 4 bar 2 legged striupp @ 4 in

ACI max spacing = max of( d/2 or 24 inch) = 4.5 inch or 24 inch

use 4 bar 2 legged striupp @ 4 in

s max = 24 inch so 1 inch provided is ok

ACI min steel max=

number of stirrup per feet = 12 number of stirrup

A planar slab of thickness of 5.00 cm has a uniform volume charge density of 7.20×10-2 C/ m3. Find the magnitude of the electric field at all points in space both inside and outside the slab, in terms of x, the distance measured from the central plane of the slab. What is the field for x = 1.25 cm? What is the field for x = 10.00 cm?

[10 marks] In the UK’s market for cars, demand D is given by D = 120 − 3p where p is the price of cars. The supply of cars is given by S = 3p. Define a competitive equilibrium for this market and find the equilibrium price of cars and the quantity traded. Draw a graph of these supply and demand functions (putting p on the “y-axis”) and illustrate the equilibrium outcome on that graph. b) [8 marks] Suppose the...
