Challenges of a Single-Layer Reticulated Inverted Monk Bowl Dome

Abstract

<p>This paper presents the challenges and studies involved in the structural analysis and design of a single-layer reticulated dome. The geometry of the dome is not conventional dome-shaped with largest diameter at the base. The dome is “Inverted monk bowl” in shape with the largest diameter at the quarter height. The dome is used as temple with a tall Buddha statue inside. It is a single-layer latticed steel dome, resting on the reinforced concrete structure. The dome is approximately 65 m in diameter at the base, while the diameter at mid-height is about 86 m. Wind tunnel test was conducted to determine the wind pressure on the surface of the dome which was located in the open terrain. High Frequency Pressure Integration (HFPI) technique was applied in the overall wind load study. Linear response history analysis was conducted to determine the response of the structure under wind load, while response spectrum analysis was conducted for seismic load. Staged construction analysis was performed in order to evaluate the performance of the structural components under construction. The structural components and construction loads were added in accordance with the actual construction sequences to determine the design forces.</p>

Soil Structure Interaction Analysis of a Single Layer Latticed Geodesic Dome

“…The construction and assembly of individual elements of a geodesic dome are much easier compared to conventional structural works (2) . Structural analysis on an inverted monk bowled shape single layer geodesic steel dome performed by Naveed Anwar (3) , it is modeled and analyzed for wind and seismic loads using the response spectrum method, the design forces are also determined with respect to the structural components and construction loads. A shake table test is performed on a single layer reticulated dome by Gui-boNie (4) , to study the dynamic behavior of the proposed model under white noise excitation and fast size frequency to exhibit the natural frequency and https://www.indjst.org/ damping factor.…”
