I. Course Outcome
II. Learning Outcome/s
III. Time Frame
IV. Introduction/Outline
: CO2: Evaluate the strength of structural plain, reinforced, or
prestressed concrete elements in axial loading, bending, shear,
torsion under pseudo-elastic and inelastic stages of loading
: LO2.1: Analyze the proportioning of member size and
reinforcement ratio of concrete elements subjected to axial
loading, bending, shear, or torsion.
: 6 Hours (School-based)
6 Hours (Home-based)
: In this module, you will analyze the inelastic behaviour of
different concrete specimens with their corresponding cylinder
strength, f’c, from the stress-strain diagram.
Below are key concepts for reading.
•
Web and longitudinal reinforcement
•
Elastic, elasto-plastic and ultimate bending
•
Allowable bending strength
•
Nominal and design bending strengths

Activity 1: Singly-reinforced rectangular beam (60 pts.)
A rectangular beam has a width 300 mm and an effective depth of 387.5 mm is reinforced with
4-25 mm ø corrugated bars. f’c = 24.13 MPa, fy = 413.7 MPa.
a) Compute the balanced steel ratio
b) Compute the tension reinforcement index
c) Compute the nominal moment capacity of the beam
Activity 2: Doubly-reinforced rectangular beam (60 pts.)
A rectangular beam has a width of 300 mm and an effective depth to the centroid of the tension
reinforcement of 500 mm. The tension reinforcement consist of 6-25 mm ø bars placed in two
rows. Compression reinforcement consisting of 2-25 mm ø bars placed 62.5 mm from the
compression face of the beam. f’c = 27.58 MPa, fy = 413.7 MPa.
a) Determine the depth of the compression block
b) Determine the maximum steel ratio
c) Determine the design moment capacity of the beam
