This report aims to raise awareness of the hazards of surface fault rupture and to identify parameters that influence structural performance during earthquake fault rupture. In researching structures subject to surface rupture, both damaged and sound, guidelines and procedures to evaluate buildings in potential hazard areas are developed herein. Little to no guidance on how to design for surface fault offset exists in current codes and design guides. Thus it is important create tools for designers to appropriately analyze structures by developing guidance and requirements to aid designers in their strength assessment of a structure subject to this particular hazard. Case studies of structures damaged by fault rupture, detailed in Section 4.0, provide important clues as to how structures respond when subject to surface offset. These case studies highlight structures that have been tested under the imposed deformations of the ground, providing insight into how building layout and construction techniques can protect the structure, even under extreme offsets. A sample evaluation for Bowles Hall (UC Berkeley) is provided herein in addition to preliminary code equations that may be used to verify and determine a structure’s resistance to surface rupture.
