2 Base Isolation of Buildings THK s base isolation systems are capable of achieving base isolation even with lightweight buildings and towering buildings, whose base isolation was difficult with the conventional systems. Buildings themselves can be designed normally. Our base isolation products are flexible earthquake-proof systems. Lightweight buildings Capable of base isolating wooden buildings, light-gauge steel structures and reinforced concrete structures. Those buildings can be designed the same as conventional buildings. Mid- to low-rise buildings Steel-framed and reinforced concrete mid- to low-rise buildings, such as complex housings and office buildings, can be base isolated. Base-isolated frame Separates the building from the ground, and serves as the base of conventional buildings. It is made from steel frames, concrete and laminate wood. Applicable to various buildings THK s base isolation systems are capable of operating even with lightweight buildings. They can base isolate not only heavy buildings that can be base isolated even with the conventional systems, but also skyscrapers, wooden houses and light-gauge steel structures. Free cycle setting Linear motion re-circulating guide CLB has a small friction coefficient ( to 0.009) and its piece-to-piece variation is minimum (0.002 or less). Therefore, the bearing is capable of extending the service life of buildings (cycle of 5 seconds or longer), which were difficult to achieve with the conventional system, through setting the recovery/attenuation mechanisms.

3 High-rise buildings and skyscrapers Since CLB has a tensile strength, it is capable of base isolating high-rise, towering buildings, whose aspect ratios are large. Because our base isolation systems support buildings, we combined THK product technologies that support these systems. THK s base isolation systems use our core products including LM Guides. Those base isolation systems, which have been developed as applied versions of our products that employ our reliability, experience, creativity and technological strengths, reflect THK s unwavering confidence. Linear re-circulating guide CLB Bearing component that combines THK LM Guides crosswise Ball LM rail LM block End plate End seal Linear guide CLB is a base isolation system that achieves a heavy sustained load and an extremely low frictional force since the balls in the LM block rotate on the raceways cut into the LM rail while circulating through the block. In addition, since the LM block retains the LM rail via the balls, the bearing can also receive a pulling load. Viscous damping system RDT A damping system that uses THK Ball Screw Motion of the shaft Internal rotation Outer tube Ball screw nut Ball screw shaft Anti-seismic base (mat foundation slab) It normally supports the weight of the building via a base isolation system, but in case of earthquake, it receives the reaction force to relieve the building from vibrations. It absorbs earthquake energy that transmits to the building with a shearing resistance of a viscous body. Viscous damping system RDT has a structure where the linear motion of the ball screw that is converted with the ball screw nut into rotary motion, and a shearing force is applied to the viscous body filled between the inner tube connected with the nut and the fixed outer tube. Recovery system (rubber material) Non-THK product Also corresponds to tower buildings Linear motion re-circulating guide CLB has a structure that also withstands a pulling load. Even if the bearing supporting a high-aspect-ratio building receives a pulling load, the building will not float. When an earthquake occurs, base isolated houses freely move in all horizontal directions from their foundations. Therefore, they need to be returned to their original neutral positions after the earthquake stops. For that purpose, those houses are equipped with this type of recovery system (laminated rubber, etc.).

4 From design of base-isolated houses to installation of base isolation systems, THK provides strong support. Building of base-isolated houses involves various steps from the design to completion, ranging from technical works, such as ground survey and structural calculation, to practical works including material supply, construction and installation.

5 Precautions on designing a base-isolated building and installing a base isolation system In building a base-isolated house, it is necessary to conduct a ground survey or the like. Since the building moves horizontally in an earthquake, there are various precautions to be observed such as securing a horizontal clearance and attention to be paid to piping. Precautions on design 1. Survey of ground classification It is necessary to conduct a ground survey (boring) or obtain data of neighboring ground. Ground classification Incidental conditions Application method Supplemental note Category 1 ground Technical standard (items 3 to 5 of Construction Ministry Notification No. 2009), or structural calculation (item 6 of Construction Ministry Notification No. 2009) and regulations on durability, etc. Category 2 ground Category 3 ground No risk of liquefaction Risk of liquefaction Time calendar response analysis, etc. and regulations on durability (ministerial approval), etc. It is necessary to take a measure to prevent the ground from subsiding such as soil improvement. 2. Securing a horizontal clearance A base-isolated house is horizontally displaced from the foundation (land) in an earthquake or the like. Taking this into account, it is necessary to secure a horizontal clearance according to the intended use. Outdoor equipment, such as that of air conditioners and boilers, must be installed on the building, instead of being placed on the foundation. In addition, it is obliged to post a notice stating that the house is baseisolated as information for third persons. This building is a base-isolated house The base-isolated house moves horizontally in a large earthquake. To avoid collision with the building, keep away from the surroundings of the building by approximately xx cm. To prevent yourself from being caught between buildings, secure an interval approximately xx cm between the building and the fence or vehicle. Example of notice board Horizontal clearance a base-isolated building is required to secure A Places used for passage by third persons Response displacement + 80 cm B Places used for passage by residents Response displacement + 20 cm C Places other than A and B Response displacement + 10 cm If the response displacement is 30 cm A 30cm+80cm=110cm B 30cm+20cm=50cm C 30cm+10cm=40cm 3. Structure of piping Base-isolated buildings are horizontally displaced from the foundation (land) in an earthquake or the like. Therefore, the piping systems such as water and sewage and gas must have flexible structures, and the electric wires and telephone cables need to have extra lengths. Precautions on installing a base isolation system 1. Accurate leveling of the anchor plate 2. Checking the steps for installing CLB and RDT (RDT centering procedure, etc.) 3. Leveling of the whole base isolation system 4. Curing after the whole base isolation system is installed 5. Removal of temporary clamps of CLB Note: It is necessary to take a measure to prevent the system from moving during the installation.

20 Precautions on Use Precautions on handing (observe the following points to avoid danger) Tilting CLB with the temporary clamps removed may cause the LM block or LM rail to slide by their own weights, and damage it or fall onto the foot to cause injury. During transportation or in any process where the product may be tilted in installation, do not remove the temporary clamps. Dropping or hitting the product may damage it. Giving impact to the product could lose its function even if it looks intact. Disassembling the product may cause dust to enter the product or degrade the assembly accuracy of parts, which could make the product unable to maintain its original performance. Do not disassemble the product. When transporting RDT, holding the ball screw may damage it. Be sure to hold RDT itself when transporting it. - Leaning down the buffer of RDT from the horizontal position may let air enter it and make RDT unable to maintain its original performance. Lubrication Do not wipe off the grease applied on the product. The system contains AFA Grease (THK product), with which we have applied for acquisition of Land, Transport and Infrastructure Minster approval for the system. When replenishing grease during installation or periodical inspection, do not replenish other grease. Precautions on use When installing the system, take care not to contaminate the system with rain, dirt or dust as much as possible, and cure the system after it is installed. In addition, remove the curing equipment before the construction of the building. Take a measure to prevent the base isolation layer from being iersed from rain during the installation work. CLB is provided with temporary clamps for preventing fall during transportation and positioning the system when installing steel frames. Remove them before the construction of the building.
