High Damping Ratio (=Earthquake Energy dissipation) than the Single lead-core rubber bearing (+20% increase)

Lead Rubber Bearing (LRB)

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.

HDRB

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.

Pendulum Bearing

Vertical Capacity : Maximum load capacity is 60,000kN
Type : Single type, Double type

Lead Rubber Damper (LRD)

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.

Toggle System

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

SMART WALL

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

SAFE DAMPER

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

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.
