As awareness around the seismic performance of buildings grows, it is becoming increasingly necessary to integrate seismic expansion joint cover systems into high performance façade systems to increase the resilience of building envelopes. Including expansion joint cover systems that accommodate seismic movement, prevent air and water infiltration, provide thermal performance and integrate seamlessly for the desired aesthetic can be challenging.
By exploring two case studies, we will highlight seismic performance considerations, design methodologies and best practices for façade integrated expansion joint cover systems. Each case study includes the key points in every phase of the design and construction process moving from conceptualization to specification, to testing and performance, as well as installation and compatibility issues. Overall, this paper provides a road map with real world examples of how to execute effective designs for expansion joint systems and integration into high performance façade systems.
In nearly every structure it is necessary to integrate expansion joint cover systems into the building envelope. As seismic design and awareness move past code compliance into performance-based design for
The Wilshire Grand project
Collaboration and integration are the cornerstones of a successful integration of expansion joint cover systems into a building envelope. Careful consideration and clear communication of project priorities and desires, including
