Expansion Joint Covers

Located on the San Andreas fault line, California building code mandates strict seismic standards for new construction.  Collaboration with CS made it possible for "The General" to be able to glide 30 inches in every direction during a seismic event.  CS' Multi-Axial Corridor Cover (MACC) system seamlessly connects the new hospital tower to the existing structure while the exterior moat covers visually unite the landscape and sidewalk with the structure

Since 1923, the Golden Bears have played football on the Hayward Fault, which runs from goal post to goal post in UC Berkeley Memorial Stadium. Seismic upgrades were necessary due to the fault’s “creep” producing numerous cracks, offsets, and gaps in the structure. The historical value of the stadium had to be considered since it was modeled on a Roman Coliseum and is on the U.S. National Register of Historic Places. The CS Expansion Joint Cover team worked closely with HNTB to create a unique system of stair risers and treads to ensure that fans, students and athletes would be safe in the event of a seismic event.

This distinctive project required careful consideration of the location of the cover. The low wall would be potentially subject to pedestrian traffic, vandalism and skateboards - all of which could damage the cover plates. CS' solution was to provide a heavy-duty stainless steel roof cover.

At the time of construction, this five-story terminal was the world's largest base isolated building. It was critical that the seismic joint covers accommodate four-way movement up to 36" with minimal impact on the design. CS helped design and detail each of the floor, wall, ceiling and exterior covers. The covers were tested to prove each design would function properly during an earthquake.

The project team utilized advanced strategies to design this fine arts museum located five miles from the San Andreas Fault. CS' MACC systems allow the corridors on the base isolated building to move up to 42" in any direction during a seismic event. On the exterior, the 60" wide custom covers are filled with the same unique, copper cladding as the rest of the building, which provides a seamless appearance to the facade. 

City Creek Center covers two city blocks in downtown Salt Lake City and includes retail shopping, residential and office buildings, as well as parking garages. Because of its location on the Warm Springs Fault, the design focused on constructing a site that could withstand a 7.0 magnitude earthquake. CS' solutions were selected because the products could be integrated into the design without disrupting the site's functionality.

CS was challenged with seamlessly integrating a custom expansion joint cover solution into the glass curtain wall facade of this new Dallas hospital. The specifications required that the system withstand daily wind, water penetration and thermal movement, while maintaining the integrity of the building's exterior. CS' system successfully passed all full-scale testing to meet the design requirements.

This sweeping building is located on 38 acres and spans 90 feet across the highway, splitting the building in half and creating unique design requirements. CS proposed a glass-filled XLS solution, which met all of the movement and design specifications without interfering with the exterior's beautiful glass facade. 

SSR

Located next to the historical landmark Corbin Building, this transportation hub required lateral movement of the 18" joint openings. CS' multifaceted design team developed unique joint covers and used XLS on the facade of the structure to incorporate a stainless steel infill panel.

Aesthetics were just as important as performance in the design of this airport. CS was called upon to incorporate unobtrusive expansion joint covers that did not impact the inside or outside of the design. CS' solution was a custom 25" XLS system that fit seamlessly within the 34" wide CENTRIA metal panels.

It was necessary to surround Los Angeles' most earthquake-proof building with CS' seismic moat covers to allow the building to withstand a maximum credible earthquake, free of gaps and openings. The SSRW seismic moat covers, MARC roof covers and XYP floor covers were designed to allow for 27" of movement. CS worked closely with the architect early on in the design of the expansion joint covers to eliminate problems that may have occurred later in the project phase.

The 383,000 square foot campus is home to 1,400 corporate employees. In order to meet the requirements of the project without compromising aesthetics, CS provided an elegant and sustainable glass-filled XLS solution.

Because structural movement could not be determined on this older building, FEMA required an unprecedented 26.6" movement for roof and wall joint covers. CS developed a custom design and confirmed its efficacy by rigorously testing the solution on their in-house cycle table. CS also provided a MARC roof cover that can withstand wind gusts of 90 PSF without component failure.

To provide a seismic upgrade to this landmark building, the architect specified CS gyrometric cabs (MACC) and SSRW seismic moat covers to work in conjunction with the base isolators to provide egress during seismic activity.

This seismic upgrade to this distinct public building called for 33" of movement in all directions. CS provided a custom SSRW system filled with stone pavers around the building's perimeter. The building is LEED® Certified at the Gold level.

This building is located three miles from the Hayward Fault and 16 miles from the San Andreas Fault, in Seismic Zone 4. The building is 12 stores high, needing to survive a 1,000 year earthquake similar to the great San Francisco earthquake of 1906. CS' XLS Series and SSR Series expansion joint covers, hidden by insetting the surrounding finish materials, were utilized in this unique moat design. Both models are able to span the 33" moat while accommodating the movement and aesthetic requirements for this landmark cathedral.

This 11-story cathedral was constructed to withstand an 8.4 magnitude earthquake. The entire building sits on base isolators, allowing it to move 24" in all directions. The moat surrounding the building is concealed by CS' SSRW moat covers, which are filled with materials that match adjacent finishes.
