新飞销售大楼结构设计中有许多技术难点,本文通过几个方面的研究分析,对这些技术难点作了必要的处理。在该工程的建筑结构中还有超出了常规的做法,为此采用了一些新的技术措施,从而使得结构体系即满足了建筑造型和使用功能上的要求,也确保了结构的安全可靠。工程中采用了大跨度次梁预应力楼盖结构,有效地降低梁的截面高度,确保层高和建筑物总高度的要求,此外还采用了超长混凝土结构无缝设计等新技术。该工程的综合技术性能指标非常好。
There are many technical difficulties in the structural design of the Xinfei Sales Building. Through several aspects of research and analysis, this paper has made necessary treatment for these technical difficulties. In the project’s architectural structure, there are still more than conventional practices. To this end, some new technical measures have been adopted. This has enabled the structural system to meet the requirements of architectural modeling and functional use, and to ensure the safety and reliability of the structure. In the project, a large-span secondary beam prestressed floor structure was adopted to effectively reduce the section height of the beam to ensure the requirements for the height of the floor and the total height of the building. In addition, new technologies such as the seamless design of the ultra-long concrete structure were adopted. The comprehensive technical performance index of this project is very good.
