What is Structural Load and how can it be
used?
The actions or forces that cause
structural loads on a structure to produce,
deform, stress, or displacement is called
structural load.
The most common types of load are
vertically applied loads and horizontally
applied loads.
Vertically applied loads are the live load
and dead loads.

a. Load Live
Over time, this load can change.
Moving furniture, walking people, and so
on are some of the best examples for live
load.
b. Dead load
This load does not change over time.
The best examples of dead loads are those
that have a self-weighted structure, such as
the weight of columns or beams.
This can be calculated using the specified
weight of the building materials and the
volume of the structural components. This
allows for a high degree of accuracy.
Based on codes, dead load = Volume for
each memberx unit weight in building
materials.
You can calculate the total dead load by
adding each structural dead load.

The calculation of loads is the core of
structural design. Nishkian, an engineering
firm, provides a concise description of
structural design: "Loads can be defined as
forces that cause stress, deformations or
accelerations. These loads are applied on a
structure or its parts that cause stress or
displacement. There are two main categories
of dead loads and living loads. What are the
differences?
Dead Loads
The dead load of a structure is its total
weight before it enters service. It is
usually measured in pounds per sq. ft. Static
loads are those that don't change throughout
the life of a building. They include floors,
walls and roofs, columns, stairs, permanent
equipment, and any decor. Nishkian said it
again: "[D]ead load accounts for the non-
dynamic, permanent forces that exert
continuous and persistent force upon a
structure."
Calculations for the dead load that a
building will take on from occupancy or use
must consider the concrete foundation, plan
building materials, and any service equipment
like elevators, HVAC units, ductwork,
plumbing and fixed manufacturing equipment.
Live Loads
The dynamic forces of occupancy and
intended use are called live loads. These are
the transient forces that move through the
building and act on any structural element.
These loads are also measured in psf and
include the expected weight of people,
furniture, appliances or other moveable
items.
In the event that loads exceed their
maximum expected live loads, the American
Society of Civil Engineers requires that the
minimum design live loads not only meet but
exceed the maximum anticipated loads for the
building's lifetime. ASCE guidelines
recommend that live loads be determined based
on the types of occupancy and uses for each
building type.
Live loads are dependent on the structural
strength of the building. It is important to
know the exact intended use of the building.
It is often determined by the strength of the
dead load or its lack, how heavy it can
withstand. Reinforced concrete not only
creates the largest dead loads, but it also
has the greatest compressive strength and can
support the most weight.
Structural steel has a lower dead load and
is better suited to support live loads in
multi-story buildings. Both engineered and
natural wood are lighter than concrete and
steel, but they can support more live loads.
The structure's "gravity load" is the sum
of its total dead and live loads. Buildings
also have to withstand additional loads.
