The Ultimate Anti-Seismic System My name is Ioannis Lymperis and I live on a small island of Greece called Ios I have a patent for the anti-earthquake technology of construction I have invented a design method and a mechanism that joins the nodes of the highest level of the structures with the foundation soil in order to stop the deformations.
The control of structural deformations in a major earthquake is associated with the brittle damage of the structure.
The question is. Do you want to work together? Do you want research collaboration to prove the theoretical and experimental results of the project? I would be delighted to have a positive answer. I have a solution to all the problems of the earthquake. My applied theoretical and experimental research has a ten-year duration.
The simplest description of the method I can do is that if we join the nodes of the highest level with foundation ground, it will withstand larger lateral overturning forces than another wall that simply rests on on the ground. If we stop the primary torque of the wall overturning by this method we have stopped the displacement of the structure. By controlling the displacement of the structure, you also control the failures .
It is a method that uses a mechanism to pontoon all the upper edges of the construction walls with earth and which dynamically deflect the lateral load of the earthquake through the vertical support of the walls and the tendon of the mechanism, and directs them into the ground controlling in this way the displacements of the construction which causes deformations responsible for structural failures on the trunks of bearing elements.
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 minimize 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 compression in the construction project.
My own experiment. The model in this experiment https://www.youtube.com/watch?v=RoM5pEy7n9Q From 2.45 minutes to 2.50 minutes, that is, within 5 seconds, made 20 journeys of 25 cm ... so in 20 seconds made 80 journeys with 25 cm of oscillation width. These oscillations from one end to the other measure, and their respective time in sec. Frequency (Hz) is the fraction: v = number of such paths / corresponding time. 80/20 = 4Hz ...9.81 is the acceleration of the earth and we divide it with the acceleration we found to find the g. That is, how many times the acceleration is accelerated by a body that falls on the earth. In a natural earthquake I did this experiment with a 0.25 cm oscillating amplitude and a frequency of 4 Hz we have an acceleration ... a = (- (2 * π * 4) ^ 2 * 0.22) / 9.81 3,14x2 = 6,28x4 = 25,12X25,12 = 631,0144X0,22 = 157,754 / 9,81 = 16 g acceleration The specimen in the experiment had a general mass weighing 880 kg. The second floor because of the inverted beam it carries is more pounds than half so I would say it is about 450kg and the ground floor is 430kg So to find the inertia force F first on the ground floor we say ... F = m.a 430 Χ 157,754 = 67834,22 Newton or 68 kN. and the first floor 450 Χ 157,754 = 70989 Newton or 71 kN. Total force F (Inertia) 68 + 71 = 139 kN Moment of inertia Strength X Height ^ 2 Ground floor 68Χ0,67Χ0,67= 30,53 kN First floor 71Χ1,35Χ1,35 = 129,4 kN Total Inertia Torque 30,53+129,4 = 160 kN
Τhe patent achieves the following
1)The consolidation of the nodes of highest level of the walls with the ground, using the mechanism of the invention, deflects the upward tensions created by the wall overturning torque transporting them freely and directly from the roof into the ground and in this way stops the displacements responsible for all growing tensions on the body of the bearing elements which they cause inelastic bending deformations and failures in a major earthquake. 2 ) Also the mechanism and method of anchoring provides very strong foundation in soft soils 3)The wall receives only compressive stresses at both ends a) at the upper end b) and the facing lower end near the base. Does not exist anymore tensile strength. This means that there are no longer torques in the nodes Does not exist anymore mechanism of concentric forces failure The floor mechanism (soft floor) does not exist anymore 4) Does not exist anymore coordination because the whole construction is shifted with the same frequency and the same oscillation amplitude 5) The wall also receives horizontal shear forces. Apply tension at all edges of the wall with the patent mechanism increases the ability to horizontal shear forces.
