RWDI was retained to study Cladding Wind Pressures, Structural Wind Loading on both the tower and the spire, Aeroelastic Effects, Helipad study and a Supplementary Damping System Concept Design. The Kingdom Tower, designed by Adrian Smith of Adrian Smith + Gordon Gill Architecture, will stand over 1,000 meters, have a total construction area of 530,000 square meters, and be at least 173 meters taller than the world's current tallest building - Dubai's 828-meter-tall Burj Khalifa. Aerolastic Concept Design: The objective of the aeroelastic model design was to match the appropriate number of mode shapes that both contributed to the overall loading and accelerations and were aeroelastically sensitive. In the course of the high frequency pressure integration study, RWDI evaluated the contribution of the first 10 modes of vibration to the overall loading and accelerations. Dynamic Optimization: This study was performed considering the variations in the dynamic properties of the tower; namely modifications to the generalized mass, generalized stiffness and damping of the first ten modes of vibration. Base/Pedestal Canopies and Helipad: This study provided the preliminary wind-induced structural design loads for the helipad and main canopies of Kingdom Tower, based on wind tunnel tests. Wind Loading for Structural Design: RWDI conducted a structural wind loading study to: • provide wind loading information for the overall structural design; and, • determine the wind-induced accelerations at the selected floor levels.
