摘要
钢筋混凝土框筒结构是工业与民用建筑筑中经常采用的结构形式之一。由于抗震性能要求的提高、使用功能的改变以及施工过程中原有设计要求的变更等原因，对已建钢筋混凝土框筒结构进行结构加固设计也是工程师在实际工程中经常遇见的设计问题之一。钢筋混凝土框筒结构的加固设计，应根据工程的实际悄况选用适宜的加固方法，进行仔细的计算验证，并与实际施工方法紧密结合，在做到安全可靠的同时满足经济合理的要求。本文结合具体的工程实例，对一幢二十一层的钢筋混凝土框筒结构的加层加固设计进行了扼要的介绍,同时对增大柱截面加固法进行了初步的探讨，本文介结的结构加固方法可供类似工程的加固设计参考。
Armoured concrete trame-tube structure is one Of the most common structure in industrial and civil buildings. The structural reinforcement of armoured concrete frame-tube which have been built is one of the important problems ioi architecture because of the improvement ot aseismatic capability, the change Of function and !he original design as well as other reasons. The structural reinforcement design should use the appropriate methods based on the actual situation, carry out a detailed calculation and authentication, and in close connection wilh the actual construction methods, so as to meet the requirements of safety and economic rationality. This article introduced the structural reinforcement design of a 21-storey armoured concrete frame-tube, and discussed the methods of increase columnar cross-section, so as Io prouide a reference in structural reinforcement design.
