3 ifference between earthquake proof, base isolation and response control arthquake proof A structure built to withstand earthquakes up to severe magnitude. Interior damage may not be prevented. Base isolation Structure uses horizontally elastic isolation devices between ground base and building structure. By lengthening the natural period and slowing vibration reduces damage to the inside of the structure. Response control Structure uses vibration dampening devices to reduce damage to the structure. Most effective against a wide range of magnitude and irregular period of earthquakes. arthquake proof Withstand vibration Strong vibration Base isolation Isolate from vibration Slow and large vibration HI-BUILAM Response control ontrol vibration Reduce vibration ffect by HIBUILAM Base isolator HIBUILAM reduces both story drift angle and shear force by up to 35-45% (25 story-building) Story drift angle Shear force HIBUILAM 3

4 Hydraulic vibration damper HIBUILAM HIBUILAM is a passive hydraulic vibration controlling device which uses fluid resistance of oil to absorb building vibration. HIBUILAM absorbs the vibration caused by large earthquakes or strong wind and have been widely applied from super high to low buildings. Improving earthquake protection and dwelling ability. Product lineups Types Series of products Product views HI-BUILAM Basic type 5kN 1kN 15kN 2kN Relief valves and other parts are built in a cylinder. 5kN 1kN 15kN 2kN ombined type of HIBUILAM and bracing. Wall stud type 5kN HIBUILAM Stud * Best suited shape for wall stud and small footprint. * HIBUILAM Stud is a name of Wall stud type HIBUILAM. 4

5 Operating principle Operating principle 1 amping force Principle of damping force The smaller the hole or the higher the velocity, the higher the pressure generated to operate the damping force. Hole Pressure amping force Velocity Operating principle 2 HIBUILAM HIBUILAM has hydraulic valves which open depending on the pressure of the oil to suppress excessive damping force and linearise damping force-velocity curve. Principle of operating Hole Piston Hydraulic valve Operating oil ylinder amping force Velocity HI-BUILAM amping force Velocity amping force amping force With a fixed size hole Velocity Velocity With hydraulic valves (HIBUILAM) Operating principle 3 Absorbing vibrational energy HIBUILAM activates through braces or wall studs to absorb vibration energy to reduce quake. Vibration energy absorbed by HIBUILAM is converted to heat through the action of operating oil.

6 haracteristics 1Bilinearised damping force-velocity curve suppresses excessive force to the building in big earthquakes. 2Steady performance in temperature variation and excitation frequency variation.(ref: page 1) 3Minimising backlash allows stable damping performance in small amplitude vibration. 4xcellent durability, features long lasting seals and high quality oil. 5asy to install with high strength bolts. 6Oil pressure monitoring bar to check oil level. *Optional 7Ball joints follow the in-plane and out-of-plane displacements. Structure HI-BUILAM Ball joint Spherical bearing in both sides enables to handle displacements from any directions. Oil pressure monitoring bar Accumulator Absorbs heat expansion and shrink of oil. Seal Access eye Seal ust seal ylinder Valve Operating oil Less secular change Piston rod aution oreign objects on piston rod may cause damage to dust seal. 6
