印象.海南岛仿生剧场是在原“海口水世界”原址上进行改建和扩建而成的,原结构看台蓬罩为悬挑13m的平板网架结构,本次按照改建和扩建的使用要求,需要悬挑25m。结合整个“海胆”的结构形态,采用7点定位技术找形6条六次抛物线,形成前后拱,巧妙地将前后拱隐藏于“海胆”内,使结构从原来的悬挑结构演化为桁架支撑拱壳结构。结合概念设计和计算分析,对桁架支撑拱壳结构体系进行系统分析,并确定了最终结构布置方案。阐述了为满足结构性能设计目标所采取的分析方法和施工措施。
Impression. Hainan Island bionic theater is in the original “Haikou Water ” on the site for the reconstruction and expansion made of the original structure of the turret as a cantilevered 13m flat grid structure, this time in accordance with the requirements of the reconstruction and expansion, Need to overhang 25m. Combined with the structure of the whole “sea urchin”, a 7-point positioning technique is used to find and form six 6-parabola lines to form anterior and posterior arches, which cleverly hide the anterior and posterior arches within the “sea urchin” so as to make the structure change from the original overhang structure Evolved into truss support arch structure. Combined with the conceptual design and calculation and analysis, the truss support arch system is systematically analyzed and the final structure layout is determined. The analytical methods and construction measures adopted to meet the structural performance design goals are described.
