Using the column interaction diagrams in Appendix A (Concrete strength = 5 ksi, steel reinforcement yield strength= 60 ksi,) with longitudinal reinforcement ration of approximately 2%, design square columns with equal reinforcement on all sides to carry each of the following loads and select the longitudinal and transverse reinforcement: 1. Pu = 2000 kips and Mu = 160 ft.kips 2. Pu = 1000 kips and Mu = 220 ft.kips 3. Pu = 500 kips and Mu = 160 ft.kips

A square tied column with f’c=5 ksi and steel with fy=60 ksi
sustains an axial load of 225 kips dead load and 375 kips live load
and a bending moment of 110 kip-ft dead load and 160 kip-ft live
load. Determine the minimum size column and its reinforcement.

The room is 5*6
Steel yield stress (fy = 60000 psi)
Concrete ultimate compressive strength (f’c = 4000 psi)
Reinforced concrete density = 150 lb/ft3.
Normal weight concrete is used.
The slab is treated as a one way slab and subjected to a dead
load of 120 psf (excluding the self-weight
of the slab) and a live load of 220 psf.
- The slab is supported by beams on the edges.
- There is a column at each corner of...

This question is referring to a concrete beam with steel rebar
reinforcement,
For a simply supported beam with width 10 inches and depth 14
inches design the steel to resist a maximum moment of 50 kip feet.
span=15 feet. Concrete 4 ksi. steel is 60 ksi.

By sketching the stress-strain curves for concrete and
reinforcement steel, explain the philosophy of idealization the
characteristic strength for concrete and reinforcement steel so to
be used in reinforced concrete design. Elaborate the importance of
such idealization in design.
