Method and system for dynamic increase of moment of inertia of any smart structure to prevent structural collapse

In many incident we can find structural collapse because of accident, or natural disaster like earthquake, storm etc. Buildings are designed to prevent different types of structural collapse. Following diagram (Figure 1) talks about structural collapse. The structure could not resists the external force.

Figure 1

The program proposes to add additional strength dynamically in the structure once any external force on the structure is detected. The additional strength will prevent structural collapse to an extent.

A software program proposes a method and system by which

1. Along with the wall of structure/building multiple multi-strips slabs are to be fixed. Such strips will be made of ductile material and will be hinged with each other to create slab. The strips will be comparatively thin in thickness.

2. Upon detecting any threshold limit external force (e.g. wind) on the structure/building, then each slab will start rolling and will act like additional beam for the external force, and columns for the building.

3. Because of rolling of each slabs, "Moment Of Inertia" will be increased drastically, so the structure/building will be stronger by a great extent.

4. Once external force reduces below the threshold limit then each slab will start unrolling and will become flat gradually. The rolling and unrolling of the slabs can be done by using hydraulic, pneumatic or with electromechanical ways.

Following diagram (Figure 2) talks about ""Moment Of Inertia"; in this case "D" is outer diameter of a role and "d" is inner diameter of the role. From the formula we can understand how the "Moment Of Inertia" will be changed based on change in diameter.

Following diagram (Figure 3) talks about by changing the position of the beam, how "Moment Of Inertia" can be changed. 1st image is having higher "Moment Of Inertia" (5.33 cm4) and thus have more bending resistance.

Following diagram (Figure 4) talks about how multiple slabs are...
