The mixed-use development was designed by MANICA Architecture and Kendall Heaton Architects. The construction was managed by Mortenson Clark Joint Venture. The arena will also have 100,000 ft2 of retail space, a 35,000ft2 plaza, and a 5.5 acre bayfront park.
Enclos was commissioned to perform the design-assist, glazing, and installation of the arena. The Enclos team fabricated and installed 160,000 ft2 of rain-screen mega-panels and secondary structure. Each mega-panel consists of roughly 7,500 panels with different dimensions. The mega-panels hang from a secondary steel structure utilizing unique trusses, transoms, and custom anchors to the primary structure. The façade includes a total of 40,000 ft2 of curtainwall on architecturally exposed structural steel (AESS) with an additional 5,000 ft2 of storefront on AESS.
The Arena is being constructed as part of a larger mixed-use development, including the Office Towers and Gatehouse. The arena is the new home to the Golden State Warriors and opened in September 2019, in time for the NBA season. The project has been designed to achieve LEED Gold certification.
Structural Design in RFEM
Enclos utilized Dlubal’s FEA software RFEM to model the Chase arena for various purposes during the pre-sale bidding process and design-assist phase. "The program was very useful for fast interoperability between Rhino + GH / Excel / RFEM. RFEM remains a very fast and efficient way compared to many other programs the Enlcos engineering team have used, continue to use, and used alternately," according to the Enclos engineers.
RFEM was utilized for the Chase Center Arena project as follows:
- Creation of the FEA model based on the proposed system by the clients / consultants
- Improvement suggestions by Enclos for the engineers' proposals
- Creation of a completely new secondary framing system by Enclos
- Report reactions based on Enclos's framing system
- Steel checks, deflection checks, reaction output - visualized in Rhino

In the case of open cross-sections, the torsional load is removed mainly via secondary torsion, since the St. Venant torsional stiffness is low compared to the warping stiffness.
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
