Carbon Steel
Plain Carbon Steel or Mild Steel

This is the most common type of steel used in building construction, which is also known as mild steel. It is incalculably strong and durable, and ensures a sturdy built.

Construction Steel
In Building Materials in Civil Engineering, 2011

3 Plasticity
The construction steel should have good plasticity. In projects, the plasticity of the steel is usually expressed by the elongation (or the reduction of cross-section area) and cold bending.

1)
Elongation refers to the ratio of the increment of the gauge length to the original gauge length when the specimen is stretched off, expressed by δ (%), shown in Figure 8.3.

Construction steels possess substantial ductility due to strain hardening and are capable of absorbing considerable energy after the initial yielding.

llowable Strength Design
For ASD, the required strength, Ra, is determined from the following load combinations (according to the AISC SCM, 13 ed.) and:[2]

D + F
D + H + F + L + T
D + H + F + (Lr or S or R)
D + H + F + 0.75(L + T) + 0.75(Lr or S or R)
D + H + F ± (0.6W or 0.7E)
D + H + F + (0.75W or 0.7E) + 0.75L + 0.75(Lr or S or R)
0.6D + 0.6W
0.6D ± 0.7E

where:

D = dead load,
Di = weight of Ice,
E = earthquake load,
F = load due to fluids with well-defined pressures and maximum heights,
Fa = flood load,
H = load due to lateral earth pressure, ground water pressure, or pressure of bulk materials,
L = live load due to occupancy,
Lr = roof live load,
S = snow load,
R = nominal load due to initial rainwater or ice, exclusive of the ponding contribution,
T = self straining load,
W = wind load,
Wi = wind on ice..
Special Provisions exist for accounting flood loads and atmospheric loads i.e. Di and Wi

Note that Allowable Strength Design is NOT equivalent to Allowable Stress Design, as governed by AISC 9th Edition. Allowable Strength Design still uses a strength, or ultimate level, design approach.
