1. dead load
maintains its size and application point for the entire life of the structure and is indicated by d.
This load is usually the weight of the structure (not just this component, but all other components on it).
This is estimated by multiplying the component volume by the standard density of the building material.
This load accounts for a large portion of the total load of the structure.
2. Live load
The load generated by the personnel and their property occupying the building, denoted by L.
Its size and application point vary over time.
If it is a bridge, the live load includes the weight of the vehicle moving on the bridge.
Typical values for common occupancy types are given below.
occupied or used
Live Load (kg/m 2)
private apartments, classrooms
fixed seats, conference hall, library reading room
movable seat assembly hall
wholesale shop, light warehouse
heavy manufacturing, heavy-duty storage warehouses, walkways and trucking lanes

constant load, designed to be determined by the weight member.
For the design, at the beginning, based on past experience, assume a reasonable self-load value and then compare it with the actual dead weight at the end.
Revise the design if necessary.
Other types of loads are wind loads, seismic loads, soil and water conservation loads, and temperature loads.
4. superimposed load
This term is used for all external loads, leaving its own weight, acting on the component to be designed.
This includes live loads, wind loads, seismic loads, etc. Partial constant loads can also be used as applied loads.
The maximum load strength expected based on a certain probability of occurrence during the life of the structure is called the working load. The
workload does not include an additional safety factor or overload factor.
6. Coefficient load
The workload that is increased by the safety factor or overload factor is called the coefficient load.
