The earthquake loads due to movement of the table and payload are transferred into the concrete floor by eight (8) anchor bolts per Earthquake Restraint. The anchor bolts (Hilti HIT RE500 SD per ICC ESR2322, 3/8 in. diameter bolts and HIS-N inserts embedded 4-3/8”) are designed for use in concrete floors at least 6 inches (150 mm) thick constructed of 2,500 psi (17.3 megapascal) minimum normal-weight concrete in an uncracked condition. If any of these conditions are not met, additional analysis and detailing by a structural engineer will be required. The earthquake loads are distributed into the optical table bottom skin by eight (8) M6-1.0 socket head cap screws pre restraint.
Each ERS2010 is rated for seismic forces generated by a maximum of 2000 pounds (908 Kg.) of combined table and payload weight per restraint. However, in order to prevent possible tipping of a table during or after an earthquake, three or more ERS2010 Restraints - located as far apart as possible at the perimeter of the table system - must be used even though the load per ERS2010 is less than the specified maximum. The ERS2010 Earthquake Restraint system is intended to work in conjunction with Newport S-2000 or I-2000 pneumatic isolators with rated load capacity 2000 lbs. The ERS2010 is designed to withstand the earthquake loads corresponding to, or lower than, the 2018 IBC seismic accelerations Ss=2.50, S1=1.00 (for example, Hayward, CA). The design of the Restraint is in compliance with 2018 International Building Code (IBC) and 2019 California Building Code (CBC).
