B. compressive load 1,200 all nodes of higher level.
The following figure shows the base shear - displacement diagram for the control node.
Figure 19. power curve ( kN ) - Displacement (m) applied compressive load 1,200 kN all nodes of higher level.

the maximum value of the diagram without the application of prestressing was
900.62 kN for displacement 0.1296 m
the maximum value of the chart by applying a compression load 1200 kN on all nodes of higher level is 1, 179.33 kN for displacement 0.0864 m
improvement in bearing capacity is
1179.33 - 900.62 = 278.71 kN
The percentage improvement in base shear is
278.71 / 900.62 = 30.9%
result
observed a significant improvement in the bearing capacity of the building, through the application of compressive forces in all nine columns of the building
Page 23 of 34
Conclusions.
when the system is applied to all columns, then leads to significantly increased values of the bearing capacity of the building.
considered that the results of the preliminary investigation are encouraging.
required
Further detailed investigation of the system in two phases.
First-level analytical simulation, which will consider more detailed models of structures with more charges.
second-level shake table experiment where you need to consider a range of construction, to scale.
To evaluate the system's behavior in real loading conditions
