The SPONSE Association is an international, nonprofit, technical society of engineers, architects, manufacturers, insurers, builders, planners, public officials, and social scientists, interested in the Seismic Performance Of Non-Structural Elements. SPONSE welcomes members from a wide range of backgrounds including research and teaching institutes, insurance groups, manufacturers of non-structural elements and individuals including engineers, architects, builders, practicing professionals, educators, government officials, and building code regulators.


The objective of the Seismic Performance Of Non-Structural Elements (SPONSE) Association is to contribute to the improvement of the resilience of communities to earthquakes by (1) Promoting research related to the seismic performance of non-structural elements, (2) Promoting education and training on subjects related to the seismic performance of non-structural elements, (3) Assisting with the dissemination of research findings and technological developments relevant to the seismic performance of non-structural elements, and (4) Facilitating collaboration between industry, academia, professionals and other parties interested in the seismic performance of non-structural elements.


The subject “Non-Structural Elements” is intended to include those elements within a building that do not form part of the primary load bearing system. It is common to distinguish between three different types of non-structural elements, as described below:

Architectural components

Architectural components are built-in nonstructural components that form part of the building. They include interior partition walls, parapets, chimneys, penthouses, suspended ceilings, appendages and ornamentation, signs and billboards, egress stairways that are independent of the building, cladding systems, window systems and lighting systems.

Mechanical and electrical components

Mechanical and electrical components are built-in nonstructural components that form part of the building. They include HVAC equipment, engines, turbines, pumps, compressors, pressure vessels, generators, batteries, motors, transformers, panel boards, switch gears, instrumentation cabinets, communication equipment, computers, cooling towers, piping systems, ductwork and electrical conduits.

Building contents

Building contents are nonstructural components belonging to tenants or occupants of the building. They include filing cabinets, bookshelves and all pieces of furniture found inside buildings.


The SPONSE Association currently has the following eight directors on its board:

Gilberto Mosqueda, University of California at San Diego, USA.

Giberto Mosqueda is an Associate Professor at the University of California at San Diego. He earned his Ph.D. in civil engineering from UC Berkeley in 2003 after a master’s at MIT and a bachelor’s from UC Irvine and he received an NSF Career award in 2008. Prof. Mosqueda’s primary research interests are in the experimental evaluation of large-scale structural and nonstructural components under seismic and other extreme loads. Current research projects focus on testing large-scale structural systems from the onset of damage through collapse using hybrid simulation and the development and verification of numerical tools to simulate structural response. Recent tests on earthquake simulators have examined limit states in seismically isolated buildings including pounding against moat walls and post-stability behavior of elastomeric bearings. New laboratory capabilities have also been developed for testing nonstructural components and medical equipment under more realistic loads including larger accelerations experienced in upper stories of buildings. The behavior of structures under multi-hazard loading is being examined, including the effectiveness of seismic design principles in mitigating collapse caused by blasts in steel buildings. Prof. Mosqueda served as the field investigation team leader for the MCEER Reconnaissance of the Gulf Coast following Hurricane Katrina and also participated in national teams investigating damage to structures and nonstructural systems following the 2010 Maule, Chile Earthquake and the 2011 Tohoku, Japan Earthquake and Tsunami.
