A seismic isolation bearing is used to protect structures from earthquake damage, minimizing the disruption to people's lives and allowing business activities to continue. Therefore, the demand for seismic isolation bearing is increasing day by day.
Lead Rubber Bearing or LRB is a type of base isolation employing a heavy damping. Heavy damping mechanism incorporated in vibration control technologies and, particularly, in base isolation devices, is often considered a valuable source of suppressing vibrations thus enhancing a building's seismic performance.
It uses rubber's high decrement to provide resilient to building and damping ratio of 10~25%. It is suitable if long-period tensile and energy dissipating capacity according to size and character of building. High decrement rubber is designed to absorb energy by adding rubber's spring factor and friction decrement factor and viscosity decrement factor in the molecules.
It is an leading edge vibration control system to minimize earthquake damage by installing Damper as an energy dissipating device on the building frame and by absorbing input energy for building to stay safely.
Lead Rubber Damper(LRD) is an energy absorption device with layered rubber and lead. It is free to design by needs as tensile control is possible by size of lead and control of rubber layer.
It consists of 2 brace members and 1 LRD to be installed in the between floors of building. Pin connection in the center is made in between angular connection part with two brace members according to design angle. In case of Lateral displacement occurrence, 2~3 times displacement and speed is delivered to LRD.
Energy absorption increases according to LRD displacement
Steel panel is displayed inside steel frame of lattice shape to improve earthquake-proof, lighting capacity and ventilation. Design demand increases according to the importance of earthquake-proof reinforcement
It is a hybrid type energy absorbing device that dissipates energy through plastic deformation of shear type friction damper and cross section steel. Friction dampers are activated during minor earthquake, and steel dampers are operated during strong earthquake. It can be installed regardless of the design of the building and movement of people.
Sky bridge is a kind of connection bridge used for leisure, fitness center and observatory as well as connection role which may maximize usability and community function. It can be an evacuation path in case of fire or emergency. There are increasing cases of sky bridge with excellent usability in accordance with current high story building trend.
