Nomenclature

Distance: millimeters and (inches) Load: Kilonewtons and (kips) Pressure: Megapascal and (Pounds per square inch)

mm = millimeter kN = Kilonewton MPa = Megapascal cm = centimeter

in = inches kip = 1000 Pounds psi = Pounds per square inch

Conversions One kip is 1000 Pounds One Metric ton is 2,204.6 Pounds One Megapascal is a Newton per millimeter squared. To convert from kip to kN, multiply by 4.4482 (Converse 0.2248) To convert from psi to MPa, multiply by 0.006895 (Converse 145.04)

Note: When ultimate design limit data is given on plans, designer needs to provide DYMAT with load factors. Data in this literature is allowable working stress design.

“The DYMAT® disc” bearing features 1. The unique shear restriction mechanism using Tyfo® alloy provides rotation with uniform distribution of forces between bearings in the structure. ®

2. “The DYMAT Disc” Gives Bearings A) Long term durability (resistant to oils, solvents, oxidation, ozone, moisture, and other ambient conditions). B) Low temperature flexibility to -73°C (-99°F). C) Design operating temperature range -73°C to 121° C (-99°F to 250° F). D) Salt water resistance. 3. High rotational capacity and the ability to rotate at low loads “The DYMAT® Disc” is designed to rotate up to 4% (0.04 radians). (The shift in center of gravity is low within structural design guideline of less than 3% of the column diameter at 1% rotation.) Full rotation at low loads is accommodated within the bearing. 4. Unique Design Principle A) The shear restriction mechanism eliminates shear on “The DYMAT® Disc” element due to horizontal forces while allowing high vertical loading on the unique material. The result is a compact bearing. B) Structural Elements have been tested to 700 MPa (101,000 psi) without material failure. “The DYMAT® Disc” is conservatively designed to a maximum design load of 35 MPa (5,076 psi) on the Tyfo® Material 5. Bearing is uncomplicated Rotation element is without critical tolerances compared to pots with sealing ring or curved mating sliding surface bearings. No greasing or PTFE lining is required to accommodate rotations.

of the total vertical load, a larger shear restriction mechanism is introduced. See page 10 for details. Standard designs for 10% and 25% are given. 9. Internal Up-lift Restraint Special bolts with Tyfo® alloy rotation elements provide up-lift restraint while allowing rotation at the same time. See page 11 for details. 10. Alternate connection details to all types of structures. See pages 12 & 13. 11. Basic bearings are standard production packages, special features are selected by designers from alternate anchorage details. 12. Special replaceability details for minimized jacking See pages 12 & 13. 13. Ease of inspection Rotation element visible from all sides. 14. Bearings are made of steel In the field of structural bearings, steel is a proven material. Special steels are available if specified. Fiber reinforced plate designs are available. 15. Unique Disc shape eliminates stress point “V” used in older designs. 16. Seismic and Base Isolation Designs available See page 14. 17. The Tyfo® element is an excellent dampening material for vibrations The dampening ratio is 0.056 for “The DYMAT® Disc.” 18. “The DYMAT® Disc” elements are self-aligning when specified.

6. Bearing design is low in overall height and is compact in plan size Final plan size based on connection details and displacement requirements.

19. Flexible guides are available

7. Confined Virgin PTFE Horizontal Sliding Surface PTFE provides low coefficient of friction against the bright annealed finished (less that 0.127µm (5 µin) root mean square finish) stainless steel. Less than 0.03 coefficient at 10.4 MPa (1508 psi) Test reports available for friction values at dynamic seismic cycling.

21. The shear restriction mechanism can be modified to allow lateral movement for a series of fixed and uni-directional bearings.

20. Jacking Ports See details on page 15.

22. A List of Project Installations is available upon request.

8. Easy Design for high Horizontal Force For designs where the horizontal force is above 25%

DESIGN BASIS “The DYMAT® Disc” 1. load is less than 3% at less than 25.4 mm (1 in) per minute sliding speed.

e at design

2. The pressure on the Virgin PTFE horizontal surface in contact with the stainless steel is a maximum of 24.1 MPa (3500 psi). (The force on the mechanically fastened PTFe guides can be used for higher pressures.) 3. Dimples can be added in the PTFe are 7mm (0.275 in) in diameter, 2mm (0.078 in) deep, and occupy greater than 20% of the PTFe surface area. Add 0.4mm (0.016 in) to the overall bearing thickness for use of dimples. High quality silicone grease shall be used. 4. The working compressive stress on “The DYMAT Disc” is less than 7% of element thickness.

Plate Design The standard lower bearing plate is designed for 20.68 MPa (3000 psi) pressure on the concrete or grout. Add-on masonry plate sizing is available upon request.

TESTING “The DYMAT® Disc” Bearing, using DYMAT ® Testing has been carried out on “The DYMAT® Disc” elements to twenty times the design load with full material recovery. Where testing is required, it is recommended that the production bearings be tested. This could be carried out on the DYMAT ® Load Test Machines.

High Horizontal Force Designs A feature of the sheer restricted disc bearing is that the horizontal forces are transfered though the central sheer restriction mechanism. The design assumes a zero load condition on the disc element. At loaded conditions the sheer strength of “The DYMAT® Disc” provides additional horizontal force capacity. The standard bearings are designed for a maximum lateral force of 10% and 25% of total vertical design load. Special design sizings for over 25% horizontal force will be provided at no obligation. Please Provide design information, as per this page, and we will provide the exact details of design.

Rule of Thumb Method of Selection

Design Information Required for Special Designs

(Where time does not allow for details to be provided)

(Design not covered by standards)

Up to 50% horizontal force, select one size larger from table and allow for thicker plates. Up to 75% Horizontal force, select to sizes larger from the table and allow for thicker plates.

(Photo copy page and send it to DYMAT® Construction Products, Inc., or our local representative.)

Note: It is important for engineer to allow a jacking place of a size large enough for a standard jack in the structure. The absence of a jacking location can make the structure impractical to lift. A liftable structure is the responsibility of the engineer or owner. Note: An alternate pin design with rounded steel pins that are in contact with the steel ring is also available.

Installation procedures 1) Procedure for a Cast-in-Place Structure 1. Cast or grout the lower central anchor or lower add-on distribution plate on the support to provide level bearing. Alternate method is to grind the concrete flat with ± 0.1 degree from horizontal. 2. Set “The DYMAT® Disc” Bearing (completely assembled from plant) on support. 3. Remove all shipping clamps or steel bands before pouring concrete. Shipping clamps must be specified by the engineer since slings are not normally used. 4. For multi-directional and uni-directional bearings, adjust upper plate to proper setting as instructed by the engineer and then cast in place. 2) Precast Structure 1. Place a plate as detailed on drawing into the precast member at the casting plant. This plate should be larger than the upper plate of the bearing to allow for field tolerances and welding of this plate to upper plate. See note on page 9. 2. Remove all shipping clamps from bearings just before setting precast members in place. 3) Steel Structure Weld or bolt upper plate of bearing to the steel structure. See details on page 12. Welding details near or on bearing to be approved by the engineer. Protective materials to be placed over bearings to protect against spark and flash. Items 1 & 2 apply to all structures with concrete supports. After installation, the bearings and surroundings shall be left clean. Temporary clamps shall be removed at the time specified by the engineer

Shipping Details “The DYMAT® Disc” bearings are shipped from the factory completely assembled and ready for installation. Bearings are disassembled in the field at the contractor’s risk unless a manufacturer’s representative is present at the site. Steel shipping bands are used and must be removed before the structure is poured or precast/steel members are lowered into place. Optional steel shipping clamps shall not be removed before the bearing is set in place in order to prevent damage to the critical components.

Jacking Ports A structure can only have replaceable bearings if the designer allows spaces to set an available hydraulic jack. Too much space can cause the need for expensive shims. Too little space can mean having to remove concrete or support jacks on foundations through the use of an expensive frame support. If the structure is not jackable, lifting should be at the owner’s expense. Conventional low profile hydraulic jacks are recommended for control on both up and down lifts.
