1. Basic drawing or sketches (plan and elevation) showing:
  1.1. Name and number of substructures (i.e. N. Abutment, Pier 2)
 
Please email the Drawing or Sketch to steve.bowman@sepbearings.com or fax it to (903) 677-4980 or mail it to 518 Progress Way, Athens, Texas 75751.
  1.2. Girder layout (number of girders and simple span or continuous)
 
Please email the Drawing or Sketch to steve.bowman@sepbearings.com or fax it to (903) 677-4980 or mail it to 518 Progress Way, Athens, Texas 75751.
2. Structure information including:
  2.1. Substructure heights (approximate is OK)
 
  2.2. Pier Stiffness (Longitudinal & Transverse Substructure Stiffness)
 
3. Service Loads:
  3.1. Dead Load and Live Load, per bearing
 
  3.2. Wind, Wind on Live, Longitudinal and Centrifugal Force, per Substructure or per line of Bearings
 
  3.3. Expansion and contraction due to temperature at each Substructure or per line of Bearings
 
  3.4. Live Load Rotation Imposed on Bearings at each Substructure or Line of Bearings
 
4. Seismic Loads:
  4.1. Acceleration coefficient and soil type (i.e. 0.2g, Soil Type II)
 
  4.2. Target seismic performance (max. force at top of each substructure, if available)
 
5. Limiting parameters, if applicable, such as:
  5.1. Maximum allowable thermal force, per substructure
 
  5.2. Maximum allowable seismic displacement
 
  5.3. Restrictions on plan dimensions or height of isolators
 
Based on the information you provide and a preliminary design performed by SEP, we will provide:
  • Bilinear and equivalent linear properties of the isolators for use in your analytical model
  • Information on modifying the response spectrum for the additional damping in the isolation system
  • Preliminary structural performance from our model including seismic force, seismic displacement, thermal forces and displacement due to wind
Upon request, SEP will provide basic geometry and price estimates for the isolators, as well as assistance with specifications and connection details.
