A technical report was received by ISTANBUL UNIVERSITY Cerrahpaşa engineering faculty. Additionally, Static and Dynamic calculations were made by our civil engineer, who specializes in steel structures and has undertaken many steel projects at home and abroad.

Dynamic analysis design is decisive. As a design criterion in dynamic analysis: The concrete block on the bed is designed to fall freely for 45 meters and hit the bed at 30m/s (108km/h). Impact time 0.005 sec. is.
-The concrete block on the bed is defined as 2.3mx2.5mx0.15m concrete.
- The weight of the concrete block on the bed was calculated as 3.3 m x 3.5 m x 0.15 m, taking into account safety and bed size optimization. Since there are changes from structure to structure, the existing columns, walls, etc. in the structure are affected by dynamic loads. Ancillary effects were not taken into account and this was used as a level of safety.
-In dynamic analysis, the first impact event with the smallest mass is the most critical situation. The concrete block that falls onto the bed after the initial impact will act as a protective shell for a living bed, almost like the shell of a turtle. Therefore, the most negative situation will naturally occur on the top floor.
According to the data obtained as a result of the dynamic analysis, it was determined that 60 concrete blocks on the bed could be transported statically with the resulting column sections.

First of all, the load issue is one of our red lines that we are very sensitive about. We changed the steel design 4 times to resist impacts due to load and destruction, and finally reached the most ideal design. To explain it simply; Steel, wood and human loads are within the standard. According to the regulations, a building floor has the capacity to carry a minimum of 350kg/m2 live load. Additionally, the safety factor is added to this.
The area to carry the bed is 3x2.75m, i.e. 8.25m2. The weight of the bed is calculated as 2,300kg including Steel + Wood + Human load. 2,300kg/8.25m2 = 278.7kg/m2. In other words, the load per 1m2 is 278.7kg. As can be seen, while the limit on the flooring is 350kg/m2, the total weight of the living bed on the floor is 278.7kg. Therefore, there is no problem with the load.

Since the bed is within the design loads of the building, it does not impose an additional load that will affect the design.

It is impossible to know which way the structure will collapse. It is not possible to design for every collapse possibility. Therefore, the bed is designed for the possibility of sandwich collapse, which is more common. Just as every object in the house has the ability to provide living space according to its occupancy, geometry and material properties, the bed will also provide protection.

The bed is included in the building design loads. These loads were taken both in the bedroom and in the children's room at the same time. Therefore, more than one bed can be used as a bed in the same residence. Areas such as the bed base etc. should not be used as storage etc.

Since 350kg/m2 in the regulation is a load that must be adhered to for every flooring you see in residential buildings, except mezzanine and roof flooring, it can be applied to every house, every room, as many as the number of rooms. If there is any doubt about the conformity of your existing structure with the regulations on paper, due to its age, etc., it should be examined by an authorized person.

It cannot be installed on points such as mezzanine floors, console floors and roof floors.

-If the room is planned in advance but the use of the bed is left to the property owner, the flooring of the relevant room can be checked as 500kg/m2 instead of 350kg/m2. This would be much more useful. In single-direction hollow block floors, beams can be added in the other direction. In the positions where the legs of the bed will be positioned, they can be placed directly on the floor rather than on the architectural material. In hollow block flooring, it is ensured that the feet come to the beams, if not, the load can be distributed with a 10mm plate.
-Moving one edge of the bed slab closer to the column-beam area instead of the middle will add additional safety in terms of general service use.

The main design of the bed is intended to prevent collapse in the form of overlapping floors, which is a situation encountered 90% of the time during an earthquake. In addition, the open side facades were considered to enable the victim to exit with his own means after the earthquake.
30 cm high protective barriers have been designed on the side facades as a security measure against dangers that may arise from tilting or sides. These barriers aim to increase the safety of the user by maintaining the stability of the bed in the event of an earthquake or other possible events. Additionally, optionally, retractable systems can be integrated into these areas.

In line with our technical university report and approval, the steel system must be built from floor to ceiling. The height in your bedroom will also be the height of the bed itself. For example, if the height of your bedroom is h = 270cm, the height of the bed will be 269-270cm.

In case of exceeding 45 meters, please consult.

For the exit route, the head of the earthquake bed should not be towards the outer wall. Instead, having the head of the seismic bed adjacent to the inner wall, especially the inner wall that is the beam, is a more suitable option to ensure better distribution of loads and structural stability.

While no deformation occurs in steel materials, there is a risk of corrosion. Therefore, it is important to protect the steel components used in the structure against corrosion. For this purpose, epoxy-based primary protective paint applications were made.

If the floors of the building collapse on top of each other due to earthquake or other reasons, the top floors will be exposed to higher forces due to the dynamic effects of the loads. Under dynamic loads, the top floors will be affected more, while the bottom floors will be less affected. Because the distribution of loads will change dynamically. It has the capacity to carry 180 tons of concrete statically on the bed. Thanks to this capacity, it carries high loads and ensures the safety of users.

Putting it in single form to be placed on the edges of walls can increase the ease of use and design flexibility of the earthquake bed. The bunk bed would be structurally stronger. However, since we have crush zones at the bottom and crown, we cannot provide sufficient volumes except for specific floor heights. Therefore, as a result of our calculations, the bunk bed system could not provide sufficient strength and was not deemed suitable.

The fact that the design is designed as a demountable system provides advantages in terms of portability and ease of use of the earthquake bed. Thanks to this feature, the bed can be easily moved and re-installed to the desired area or apartment.
