I am particularly excited to share with you the results of my extensive independent research in the field of seismic technology. My work focuses on developing innovative methods and techniques that can enhance the resilience and safety of buildings during seismic events.
What I Am Researching
I have developed a mechanism that is placed at the depths of boreholes and expands by pressing against the borehole walls with the help of hydraulic jacks positioned at the ground surface, achieving a strong anchorage to the soil. This mechanism is capable of withstanding tensile forces of several hundred tons.
What I Aim to Achieve with This Mechanism
- Anchoring Wind Turbines to the Ground: Eliminating the need for conventional concrete foundations that rely on gravity, thereby reducing wind turbine support costs by 90%.
- Connecting the Ground to Structural Walls: Preventing overturning moments that break beams and lead to structural collapse. By inducing compressive forces in the walls, I prevent their bending and increase their seismic resistance. Essentially, I enhance the structure’s dynamic performance without increasing its mass, preventing earthquake-induced failures by utilizing the strength of the ground.
My research is not limited to theoretical studies but also includes experimental testing that validates the effectiveness of these technologies. I believe that applying these methods to existing or new engineering projects, as well as bridge construction, holds great practical value and can significantly contribute to the protection of human lives and property.
I would be delighted to share more details and discuss potential collaborations or applications of these technologies. I hope you will have the opportunity to review my findings and provide me with your insights.

[Abstract
The design mechanisms and methods of the invention are intended to minimize problems related to the safety of structures in the event of natural phenomena such as earthquakes, tornadoes, and strong winds. It is achieved by controlling the deformations of the structure. Damage and deformation are closely related concepts since the control of deformations also controls the damage. The design method of applying artificial compression to the ends of all longitudinal reinforced concrete walls and, at the same time, connecting the ends of the walls to the ground using ground anchors placed at the depths of the boreholes, transfers the inertial stresses of the structure in the ground, which reacts as an external force in the structure’s response to seismic displacements. The wall with the artificial compression acquires dynamic, larger active cross-section and high axial and torsional stiffness, preventing all failures caused by inelastic deformation. By connecting the ends of all walls to the ground, we control the eigenfrequency of the structure and the ground during each seismic loading cycle, preventing inelastic displacements. At the same time, we ensure the strong bearing capacity of the foundation soil and the structure. By designing the walls correctly and placing them in proper locations, we prevent the torsional flexural buckling that occurs in asymmetrical floor plans, and metal and tall structures. Compression of the wall sections at the ends and their anchoring to the ground mitigates the transfer of deformations to the connection nodes, strengthens the wall section in terms of base shear force and shear stress of the sections, and increases the strength of the cross-sections to the tensile at the ends of the walls by introducing counteractive forces. The use of tendons within the ducts prevents longitudinal shear in the overlay concrete, while anchoring the walls to the foundation not only dissipates inertial forces to the ground but also prevents rotation of the walls, thus maintaining the structural integrity of the beams. The prestressing at the bilateral ends of the walls restores the structure to its original position even inelastic displacements by closing the opening of the developing cracks.]
