A singly reinforced rectangular section has a width of 250mm and an effective depth of 460mm. The concrete has a compressive strength of 21MPa. The steel has a yield strength of 275 MPa and E = 200,000 MPa. Calculate the ideal flexural strength for the following areas of steel: a. 2580 mm² b. 5160 mm² c. The value at balanced failure
3. The block is subjected to a triaxial loading as shown. If v = 0.30 and E = 29 x 106 psi, determine the following: a) the single uniformly distributed load (in kips) in the x-direction that would produce and the same deformation in the y-direction as the original loading b) the single uniformly distributed load (in kips) that must be added in the load which exists in the x-direction to produce no deformation in the z-direction. HINT: No deformation in the z-direction means there is no strain in that specific direction but is still subjected to a particular stress. With that, correlating different strains by Poisson's ratio may not be applicable in this part. Use 6 decimal places for the solved values of strain and 3 decimal places in other values. y 60 kips 48 kips 54 kips 2" 54 kips 48 kips x. 3" 60 kips 4"
