143 Category 4: Special Projects 4 Owner US Government - Department of State Architect Allied Works Architecture & Yost Grube Hall Archi- tecture General Contractor Pernix Construction Engineering Office KPFF Consulting Engineers Construction Period 07/2016 - 01/2019 This project contains numerous speciality elements, including roof trellises with unusual shapes and supports and a series of three-dimensional façade elements appended to the main office building that are configured to act as screening elements and, which vary in size and shape. Both the trellises and the façade elements will be fabricated from ultra-high performance concrete (UHPC), which does not require traditional steel reinforcing bar. This material is used to minimize the thicknesses of these elements and to enhance element durability to meet the US government 100 year design life for buildings internationally. Early in the project the façade was an integral part of the exterior structure of the building and supported gravity loads. SCIA Engineer was used to analyse this structure for typical gravity and wind loads and for analysis under progressive collapse situations in which a portion of the exterior wall is removed, as would occur under a severe blast event. During the construction documentation phase, this wall was pulled off the building due to constructability concerns in southern Africa. The façade elements were then analysed for hurricane-force wind loads and gravity loads. The trellis elements will also be made of UHPC. SCIA Engineer was utilised to verify the stresses due to their unique and changing shape and was used for analysis of each unique roof. A multitude of various cantilever conditions and backspans made SCIA’s load panels and CAD import invaluable.
