[摘要] 拱结构常用于桥梁以及大跨结构中,在外荷载作用下,拱主要承受压力,以避免不利的弯曲变形,充分发挥混凝土材料的优势。在北海某超限高层住宅结构中,采用随形拱壳来实现建筑物立面开大洞口,是一次大胆尝试。结合该建筑物的特点,实现了建筑师的大胆意图,提出了合理的结构计算方法和设计措施以保证结构安全。

Abstract: Arch structure is usually adopted in bridges and other large-span structures because of its pressure characteristic under vertical loads, which enables the full utilization of concrete strength. In case of large scale vertical opening in an irregular high-rise building, a natural shape arch-shell structure is used as an innovation. In addition to optimize the concrete structural performance, the original architectural idea was brought to realization. Reasonable computing methods and construction details were proposed in order to guarantee the safety of the building.
Keywords: natural shape arch-shell; irregular high-rise building; opening in building; multi-tower structure
