摘要:随着市场经济的发展和需求，越来越多的酒店和办公楼建筑拔地而起，对于旋转楼梯元素的运用也越来越广泛，然而旋转楼梯的施工也一直面临着技术上的难点，文章结合实际工程项目案例，阐述了BIM技术在旋转钢楼梯设计施工中的运用，为这类项目提供了一种全新的处理方法，从源头节约成本，加快施工进度，保证质量，提高效率。

Abstract: With the development and growing demand of our market economy, increasing numbers of hotels and office buildings grow abruptly form the ground, with more extensive applications of the rotating stair elements. However, the construction of the rotating staircase has also been faced with technical difficulties. This paper applies some project case studies to illustrate the application of BIM technology in the design and construction of the rotating steel staircase, which provides a new method for such project to save the cost from the source, to speed up the construction progress, to ensure the quality, and to improve the efficiency.
