Loads of the structure itself: includes the weight and pressure of the structure itself, which is caused by the weight of the structure and other loads.
Independent loads: includes other loads that are applied to the structure, but are not related to the weight of the structure. For example, wind load, snow load, rain load, earthquake load, damage repair load and additional load can be included in this category.
Changeable loads: includes loads that change over time due to changes in the environment and conditions of the structure. For example, wind loads, ambient temperature changes and air humidity changes can be included in this category.
Operational loads: include loads that are created on the structure due to the use of the structure by people, machines, materials and other objects. For example, vehicle weight loads, storage material loads and loads that enter the structure through the entrance gates.
Unforeseen loads: includes loads that may be applied to the structure due to unexpected factors such as fire, explosion, flood, earthquake and other catastrophic events.
In general, for the design, construction and maintenance of the building structure, attention must be paid to all the different loads that may be applied to the structure, and for each load, its amount and how to apply it to the structure should be calculated. It should also be noted that in the design of the structure, loads are calculated with an additional safety factor, so that in case of unforeseen loads, the structure suffers less risks. For this purpose, the use of numerical methods and computer simulations can help designers and engineers to calculate the loads on the structure more accurately.
Also, to prevent human and financial damages caused by unexpected loads, structures need to be designed and built using appropriate materials and methods. In this regard, the use of materials such as steel and reinforced concrete and the use of new and advanced technologies in the design and construction of structures bring a significant improvement in the performance and safety of structures.
