We plan ductile structures, but we also need the torsional stiffness to stop the torsion of asymmetric floors.
Design methods yield (or else plastic zones) which are default locations of failure to be the first ultimate-yield in a powerful earthquake.
My invention provides...
a) vertical elements .... 1) stiffness 2) resistance to shear force 3) greater resistance to horizontal load 4) less deformation 5) strong foundation.
b) Better methods yield-or else plastic zones

Brief description of the invention
The principal object of the hydraulic tie rod for construction projects of the present invention as well as of the method for constructing building structures utilizing the hydraulic tie rod of the present invention is to minimise the aforesaid problems associated with the safety of construction structures in the event of natural phenomena such as earthquakes, hurricanes and very high lateral winds. According to the present invention, this can be achieved by a continuous pre-stressing (pulling) of both the building structure towards the ground and of the ground towards the structure, making these two parts one body like a sandwich. Said pre-stressing is applied by means of the mechanism of the hydraulic tie rod for construction projects. Said mechanism comprises a steel cable crossing freely in the centre the structure's vertical
support elements and also the length of a drilling beneath them. Said steel cable's lower end is tied to an anchor-type mechanism that is embedded into the walls of the drilling to prevent it from being uplifted. Said steel cable's top end is tied to a hydraulic pulling mechanism, exerting a continuous uplifting force. The pulling force applied to the steel cable by means of the hydraulic mechanism and the reaction to such pulling from the fixed anchor at the other end of it generate the desired prestressing in the construction project.
This prestressing ensures to the vertical elements of 1) greater stiffness 2) resistance to shear force 3) greater resistance to horizontal load 4) less deformation 5) strong foundation.
b) Better methods yield-or else plastic zones
In the video we see two static systems....one inside the other.
The first prestressed rigid structure has 1) greater stiffness 2) resistance to shear force 3) greater resistance to horizontal load 4) less deformation 5) strong foundation,...to receive large shocks from ductile static carrier and stop the deformation of ductile static carrier.
At the height of the plates created seismic joint for two reasons
1)The seismic joint gradually grows on the upper floors to avoid transferring loads to the lower floors, derived from the primary impact plate - elevator shaft
See the plan

2)For to separate the vertical rigid elements of the ductile elements for better cooperation between these two structural systems
The seismic joint gives freedom to all the free movement of ductile construction which itself is a mechanism amortization of seismic energy.
Amortization of seismic energy ensures the invention of the video .. to
1) The hydraulic system on the roof.
2) The seismic joint
3) The horizontal seismic isolation
These two structural systems can work together as we see in the video

or we can only use the rigid structural system itself to build rigid structures, as indicated by the links
