In the design of the building structure, access to the various components of the building and facilitating maintenance operations and subsequent repairs are of particular importance. If the access to the components of the building structure is not provided properly, the subsequent maintenance and repairs will be accompanied by many problems and difficulties, and in some cases it will not be possible at all. Also, in case of an accident and there is a need for people's safety and quick exit, access to the building with sufficient safety is of particular importance. Therefore, in the design of the building structure, access to all components of the building structure and safety for people must be provided.
One of the principles of building structure design is providing access to the structures and equipment inside it. This issue is necessary for maintenance, repair and reconstruction of structures and equipment. For this reason, in the design of the building structure, the access points, stairs, corridors and other paths that are needed to access the structures and equipment must be designed accurately.
In addition, access to the building structure must be such that it ensures the safety of people and complies with safety regulations and standards. For example, stairs and corridors should be wide enough for people and equipment to pass through, and they should be made of fire-resistant materials. In general, access to the building structure is one of the important factors in the safety and health of employees and users and should be considered seriously.
