Steel Designers' Manual - 6th Edition (2003)
Floors require further consideration regarding the choice of construction (see
section 3.2.3) and loading requirements (see section 3.3.1).
3.1.2 Power station structures
Range of structures and scale of construction 95
Industrial steelwork for electrical generating plants varies considerably depending
on the size of station and the fuel being used. These variations are most marked in
boiler house structures; whereas coal-fired and oil-fired boilers are similar, nuclear
power station boilers (reactors) are generally constructed in concrete for biological
shielding purposes, steel being used normally in a secondary building envelope role.
Turbine halls are, in principle, largely independent of fuel type, and many of the
other plant structures (mechanical annexes, electrical switchgear buildings, coal
hoppers, conveyors, pump-houses) are common in style to other industrial uses and
so brief descriptions of the salient design features are of general interest.
Boiler houses (coal- or oil-fired) (Fig. 3.1) have to solve one overriding design
criterion and as a result can be considered exercises in pure structural design.
