Obelisks presented an important element in the architecture of ancient Egypt. This research is concerned with the re-erection of an obelisk that belongs to the famous Pharoah Ramses II. It was found broken and was transported to the Grand Egyptian Museum for restoration and display. An observation of Ramses II Cartouche at the bottom side of the obelisk base inspired the authorities to provide an innovative architectural design to display the obelisk elevated. The supporting structure was designed to allow the visitors to walk underneath the obelisk and observe Ramses II's signature. The idea of elevating the obelisk presented several challenges including evaluating the obelisk's current condition, restoration and fixation methodology, structural stability, and uncertainties of material characteristics, amongst others. To control the obelisk deformations under lateral loading, state-of-the-art base isolators were introduced. For the task to be achieved, a multidisciplinary team including historians, conservators, archaeologists, architects, and engineers with different specialties was appointed. The team performed the task successfully and currently, the obelisk stands at the entrance piazza of the Grand Egyptian Museum representing the world's first elevated obelisk.
方尖碑是古埃及建筑中的一个重要元素。本研究涉及到重新竖立一座属于法老拉美西斯二世的著名方尖碑。这座方尖碑已断裂,被运到大埃及博物馆进行修复和展示。在方尖碑底座的底部观察到拉美西斯二世的卡图什,这启发当局提供一个创新的建筑设计来展示方尖碑的提升。支撑结构的设计允许游客在方尖碑下行走,并观察拉美西斯二世的签名。提升方尖碑的想法带来了一些挑战,包括评估方尖碑的当前状况、修复和固定方法、结构稳定性以及材料特性的不确定性等。为了控制方尖碑在侧向加载下的变形,引入了最先进的基础隔震器。为了完成这项任务,任命了一个多学科团队,包括历史学家、文物保护者、考古学家、建筑师和工程师,他们具有不同的专业知识。该团队成功地完成了任务,目前,这座方尖碑矗立在大埃及博物馆的入口广场上,代表着世界上第一个提升的方尖碑。
