RESTON®POT bearings
Introduction
The following tables indicate the dimensions of standard RESTON®POT bearings with
vertical load capacities of up to 75 MN. Minimum movement capacities, supplemental
movements and minimum dimensions as specified by the standard EN 1337 are incorporated in the design. It should be noted that bearing heights can vary by up to 10 mm as a
result of fabrication tolerances.
⑦
⑤
In determining bearing dimensions, assumptions were made as described below.
Load combinations
⑥
Bearings are dimensioned to resist the maximum vertical and horizontal forces indicated
in the tables.
Maximum permissible horizontal loads are assumed to act only in combination with a
simultaneously acting vertical load of approximately 40 % of maximum (with friction thus
resisting some of the horizontal force). More demanding load combinations must be
checked individually.
④
②
③
The relevant parameters are:
• NRd: Maximum vertical load capacity of the bearing (ULS)
①
• VRd: Maximum horizontal load capacity of the bearing (ULS), under a vertical load of
40 % of NRd
• Nd,min: Minimum required vertical load with a simultaneous horizontal load, VRd (ULS)
It is assumed that friction can be considered to resist some of the horizontal force (with
the exception of railway bridges and seismic loading).
The load combinations are in accordance with EN 1991. If the design loads are not in accordance with this standard, detailed design will be carried out in accordance with the
applicable norm (e.g. AASHTO, BS, SIA, etc.).
Concrete strength
The pressure acting on concrete main structures is calculated in accordance with EN 1992
(partial surface pressure). Design requirements are generally fulfilled if concrete of class
C30/37 or higher is used and the load distribution area in the concrete structure is approximately 1.6 times the base area of the pot.

Movements
• TE bearings: Total longitudinal movement of 100 mm (+/- 50 mm)
• TA bearings: Total longitudinal movement of 100 mm (+/- 50 mm), and transverse
movement of 40 mm (+/- 20 mm)
Bearings can also be designed for larger longitudinal and transverse movements. This
requires the dimensions of the sliding plate, the height and the upper anchorage to be
adapted. For longitudinally fixed TE bearings, the movement is normally reduced.

Structural bearings
Typical dimensions – Type TE
RESTON®POT bearings of type TE can move along one horizontal axis and resist horizontal forces transverse to that axis, while accommodating rotations about every axis. The bearing is connected to the superstructure and substructure by means of dowels or anchor
plates with shear studs.
Small bearings are generally equipped with external guide bars (type “a”), for space reasons. Larger bearings are normally equipped
with an internal guide bar along the bearing’s axis (type “i”). Depending on the size of the horizontal force in relation to the vertical
force, bearings of intermediate size can be equipped with external or, as provided here, internal guide bars.
Bearing dimensions and weights for deviating requirements can be determined on request.
