Question

a rectangular beam having dimensions: b=300mm and d=550mm, spans 6m face to face of simple supports. it is reinforced for flexure with 3D36mm bars that continue uninterrupted to the ends of the soan. it is to carry a service dead load of 23.8 KN/m (including self-weight) and a service lice load equal to 47.6 KN/m, both uniformly distributed along the span. use fc’=27.6 Mpa and fy=414.7 Mpa. Normal weight concrete will be used and diameter of stirrup are 10mm.

1.using the simplified equation, what is the nominal shear capacity of concrete at a section 1m from the support?

2. using the exact equation, what us the nominal shear capacity of concrete at a section 1m from the support?

3. using the simplified equation to evaluate the shear capacity of concrete, what should be the ultimate shear strength provided by web reinforcements at a section 1m from the support?

4. based on NSCP code provisions and the simplified equation to evaluate the shear capacity of concrete, what is the maximum allowable spacing of stirrups at a section 1m from the support?

5. usung simplified equation to evaluate the shear capacity of concrete, what is the required spacing of stirrups at a section 1m from the support?

6. using the simplified equation to evaluate the shear capacity of concrete, theoretically web reinforcement will not be required at what section of the beam?

Answer 1

I didnt solve the 4th one , depend on Nscp code . I have shared all the answers , thankyou
