采用预应力混凝土是改善结构使用性能、节约钢材和能源、满足建筑空间要求、提高综合经济效益的重要措施。预应力混凝土结构与普通混凝土结构相比有跨度较大、挠度和裂缝较小的优点;和结构相比能降低造价和日常的维护费用,而且防火性能较好。因此,大力发展预应力混凝土结构是与现阶段我国国情相适应的。但在设计中有一些问题不容忽视。本文在这方面提出了作者的一些观点供大家参考。
The use of prestressed concrete is an important measure to improve the structural performance, save steel and energy, meet the requirements of building space, and improve the overall economic efficiency. Compared with ordinary concrete structure, prestressed concrete structures have the advantages of larger span, less deflection and cracks, lower cost and daily maintenance costs compared with the structure, and better fireproof performance. Therefore, the vigorous development of prestressed concrete structures is in line with the present situation of our country. But there are some problems in the design can not be ignored. This article put forward some views of the author for your reference in this regard.
