STRUCTURAL ANALYSIS
A 6m simply supported beam is loaded with a 12 kN-m concentrated moment placed 2m from the left support and a concentrated load of 24 kN located 2m from the right support. The flexural rigidity of the beam is EI.
Calculate the slope of the tangent at the left support.
Determine the rotation at the right support.
Find the deflection at the point of application of concentrated moment.
What is the maximum deflection of the beam?
GROUP 1
Design a simply supported prestressed beam to support a parking space with a harped
tendon using the ACI 318 Building Code allowable stresses.
The span length will be decided by the pair.
The pair has to choose a suitable sustained service live load (from 300-1500plf) and
superimposed dead load (50-150plf) and has no concrete topping.
Assume the beam is made of normal-weight concrete with fc'= 5,000 psi and that the
concrete strength f'ci at transfer is 70 percent of the cylinder strength.
. Also, the pair must assume a justifiable time-dependent loss.
•
Assume that that fu = 260,000 psi for stress-relieved tendons, ft = 12sqrt(fc').
THE PAIR MUST BE ABLE TO DEFEND THE LENGTH OF BEAM, AND THE LOADINGS
APPLIED ON THE BEAM.
