SIPs certainly are a strong structural panel building component utilized in residential homes and commercial buildings for your walls, roofs and floors. SIPs use a good reputation for performance in seismic events. In particular, numerous SIP structures were located near to the epicenter with the magnitude 6.9 earthquake that struck Kobe, Japan in 1995. A review of these structures after the earthquake indicated that the inherent performance of SIPs in seismic events is exceptional.
SIPs develop their shear strength from the use of outer facings of 7/16" OSB produced in conformance using the PS2 standard for sheathing. Each SIP wall panel is linked to base plates, top plates, and vertical boundary members with fasteners, typically 8d nails. The 8d nails provide for the transfer with the shear loads from your OSB facings towards the wood plating materials while the bond with the OSB towards the EPS core provide resistance for your OSB from buckling. This performance is analogous to conventionally built OSB sheathed shear walls the location where the OSB provides shear resistance through the use of fasteners to transfer shear loads for the framing members.
SIPs have been evaluated side by side with OSB sheathed conventional walls. Testing has been conducted by the leader in the progression of shear wall design data for light frame walls, APA - The Engineered Wood Association. Testing contains building conventional OSB sheathed 2X shear walls and comparing the performance to Structural Insulated Panels.
Testing was conducted using a seismic test protocol developed by the Structural Engineering Association of Los angeles (SEAOSC). Test contains imposing a simulated seismic event to some shear wall and recording the response. The exam protocol includes 72 cycles of loading for your shear wall. The resulting loads and deflection for that conventional shear wall and the SIP wall were nearly identical.

It is recommended that SIPs are similar to conventional light frame shear walls with OSB sheathing for performance in seismic events with proper engineering of connections and load transfer.
