Earthquake is a natural periodic event that destroys lives and property. It does not matter when it happens, since it does happen. The science of civil engineering around the world tries to keep constructions upright. To achieve this it tries to bring in opposition to the seismic forces of the earthquake opposing forces coming from the construction. It is understood and accepted by all that any force that resists the force of an earthquake is desirable because we all know from physics that equal and opposite forces balance. I make a suggestion to those who write the anti-seismic regulations, and for some unknown reason they do not listen to me. For the first time in the world, I propose that this force that resists earthquakes should not only come from the dynamics of construction but also from an external factor, that of the ground. This external force can by itself balance the forces of the earthquake or work with the forces of construction to balance the forces of the earthquake together. It is at least very strange that they refuse to consider this proposal of mine. I accuse them at least of impartiality and irresponsibility. https://www.scirp.org/journal/paperinformation.aspx?paperid=59888
Yes dear Jiří Kroc You will find theory in this article in the attachment And experiments on my channel https://www.youtube.com/channel/UCZaFAWh80Zs3gvEulYCex2A?view_as=subscriber I also accept research collaborations.
Preprint DYNAMICS OF CONSTRUCTIONS RESEARCH
Dear Apama Sathya Murthy. All new constructions are shielded against earthquakes until the next big earthquake.
The anti-seismic construction technology has modern and good anti-seismic regulations! However, the structures do not withstand any major earthquake. There are too many unpredictable factors that can bring destruction to what modern earthquake structures. The factors that determine the seismic behavior of structures are numerous, and in part probable. Unknown direction of the earthquake, unknown exact content of seismic excitation frequencies, unknown its duration. The maximum possible accelerations given by the seismologists, and determining the coefficient of earthquake resistance design, have a probability of exceedance of more than 10%. The correlation of quantities such as "Inertial tensions - damping forces - elastic forces - dynamic construction features - soil construction interaction - imposed ground movement " is non-linear, directional. According to the modern regulations, the seismic design of the buildings is based on the requirements of efficient node design and ductility. The inevitable inelastic behavior under strong seismic stimulation is directed to selected elements and failure mechanisms. The incompetence of the nodes, and the limited ductility of the elements, will produce blatant forms of failure. The purpose of the modern anti-seismic regulation is to construct structures that: a) In frequent small earthquakes, with a high probability to happen, construction will suffer nothing, b) In medium-sized earthquakes, medium probability of becoming, construction will suffer minor repairable damage and c) In very strong earthquakes, little chance of happening will have no losses of human lives. So we should not use the term "The Ultimate Anti-Seismic Design." We should use the term "Quality constructions" This means applying the requirements of all modern regulations. The quality of construction and its safety is also a function of the economic situation of the countries. It is understandable that poor countries can not be compared with countries where they have very expensive modern anti-seismic regulations. Conclusion ... there is no Ultimate Anti-Seismic Design today, and we should not refer to Ultimate Anti-Seismic Design. So, there is a great need today to invent the Ultimate Anti-Seismic Design with lower construction costs.
I share your opinion and support your ideas and suggestions. It is for the benefit of humanity and reducing losses caused by earthquakes.
