THE BOW, ENCANA'S NEW CORPORATE HEADQUARTERS IN CALGARY

摘要

The Bow is a new iconic building by Foster + Partners of London. This crescent shaped 59-storey tower features a vast atrium partitioned in four clear height sectors of 24, 18, 12 and six storeys. The façade of the atrium is an architectural exposed "diagrid" (diagonal grid) structure in six-storey segments that act as one of the building's six separate systems making up the hybrid lateral force resisting system (LFRS). The other LRFS include a W-shaped rigid frame at each end of the banana-shaped structure, and two additional "diagrid" sectors on either side of a concentric and eccentrically braced area framed through the core. The building also features long-span composite beams creating core-to-perimeter wall open spaces.
