energy dissipation capacity in a lead-core rubber insulator<\/p><p>Lead core that has sufficient energy dissipation capacity decreases lateral displacement on seismic isolator. LRB has nonlinear force-displacement behavior like hysteretic dampers. As lead core is exposed ta shear force causing nonlinear deformation from steel reinforcing layers, it dissipates energy in hysteretic loop after yielding sa Arsan ATLAS\u00ae LRB achieve an equivalent viscous damping coefficient between \n and .<\/p><p>The amount of dissipated energy by lead rubber bearing is equal ta the area under the graph of hystereticloop. Far each loop, kinetic energy is dissipated and turns ta heat energy. Rubber behaves linear up ta strain \nrate between %1 DO and 0. Thus, the internal rubber layers provide great flexibility in lateral direction with low shear modulus.<\/p><h3><strong>Seismic Isolation and Purpose<\/strong><\/h3><p>Seismic isolation principle is ta isolate the superstructure from substructure with a bearing that vertically stiff but horizontally flexible. This flexibility lengthens the fundamental period of the isolated building and reduces the seismic forces in the superstructure.<strong>.<\/strong><\/p><p>When an isolated structure is subjected ta an earthquake, the deformation occurs in the isolators rather than the substructure elements. The effects of earthquake forces on the structures can be decreased with this method since seismic isolators dissipate energy ta limit relative displacements. in the economic way, that system allows ta use smaller sections far structural elements.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1690\" src=\"https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/Bina_-2.jpg\" alt=\"\" width=\"1200\" height=\"596\" srcset=\"https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/Bina_-2.jpg 1200w, https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/Bina_-2-300x149.jpg 300w, https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/Bina_-2-1024x509.jpg 1024w, https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/Bina_-2-768x381.jpg 768w, https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/Bina_-2-16x8.jpg 16w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p><p style=\"text-align: left;\">Seismic behavior of conventional vs seismic isolated structures<\/p><p style=\"text-align: left;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1691\" src=\"https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/izo_2.jpg\" alt=\"\" width=\"562\" height=\"193\" srcset=\"https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/izo_2.jpg 562w, https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/izo_2-300x103.jpg 300w, https:\/\/www.arsan.com\/wp-content\/uploads\/2020\/10\/izo_2-16x5.jpg 16w\" sizes=\"(max-width: 562px) 100vw, 562px\" \/><\/p><p>lncreasing natural period of the structure causes the increase in displacements and the effective reduction in floor accelerations.
