Engineering

The building is made of reinforced concrete upon a solid core, perimeter framing, and pretensed concrete floors. At its ends, the tower has metallic diagonals as energy dispersers that educe distortion during earthquakes. Its design was assessed by international experts with extensive experience in the creation of skyscrapers and was made in conformity with strict international standards as well as all Chilean norms with respect to seismic buildings.

Wind Tunnel:
The Titanium La Portada Tower was submitted to wind tunnel tests by the RWDI Anemos Agency, the consultant for the world's foremost skyscrapers. These analyses provided important information regarding where structural stress occurs during extreme winds, which facades are most affected, and what kind of turbulences might occur at the pedestrian level, on the heliport and terraces. As a result, modifications to the design were made until the most efficient and safest streamlined shape was achieved.

Energy Dispersers
The energy dispersers make it possible to build structures of economical heights while offering high levels of security during severe earthquakes. The dispersal of energy is enabled by the introduction of special devices in the structure in order to reduce distortions and structural stress.

These devices reduce the effects of distortion and stress produced by an earthquake or strong winds, as they increase structural absorption. As a consequence, the levels of stress inflicted on the structure by an earthquake can be up to 50% less than those of a structure without energy dispersers.
