Structure & Facade

The two towers rely on different structural systems, reflecting distinct engineering strategies.

The 5900 Wilshire Building uses a Framed Tube In Tube structural system, which combines a strong central core with a perimeter tube of columns, while the Equitable Life Building uses a Frame system, that relies on a regular grid of columns and beams to sustain its weight.

Yet, when it comes to their facade, they both employed the same solution, a Curtain Wall facade.

A curtain wall is a non-load-bearing facade hung from the structural frame. It is anchored to floor slabs and transfers only its own weight and wind loads, allowing for sleek, glassy exteriors.
