What is the maximum spacing by code not by strength for stirrups in a RC beam if the shear strength required by the steel is more than twice the strength of the concrete? 'd' for the beam is 20 inches. 10" 24" 12" 5"

Choose only correct answer/option.

Problem No. 3A beam 200x450mm is reinforced by 2-32mm diameter rebar. Assume Cc-50mm, stirrups-10mm, fc'-21Mpa and fy-415Mpa. Calculate the following. 17. Calculate the strain of the steel reinforcement O 0.00182 O 0.00201 O 0.00224 O 000391 O 0.00577

In designing a RC beam, actual steel ratio is kept well below the balanced steel ratio. What are the reasons behind it.?

H.W.11: Calculate the design bending strength for the doubly reinforced rectangular section shown below where A' (3025), A, (6025), f = 34.5 MPa and fy = 414 MPa. 3025 mm 450 mm 6025 mm 250 mm 50 mm 475 mm

For shown single angle, neglecting block shear strength: The shear lag coefficient is ... The governing net area is...... The effective area..... '1 The allowable tensile strength is 0 O 3@1½ O L 8x4x9/16 1½" -½" gusset plate

Check the following reinforced concrete beams for bending. The beams are on a simple span of 26.5ft. They support uniformly distributed service loads of 3.20 kip/ft live and 1.80 kip/ft dead excluding beam weight. Assume the 28 day strength of the concrete is 3000 psi and the rebar is Grade 60. 5-#9 ㅏ 16' (a) 35' 38'
