基于实际工程的钢筋混凝土框架结构加固技术研究

Research on reinforcement methods of reinforced concrete frame structure based on a practical project

对需要进行钢筋混凝土框架结构加固的情况进行了阐述,分别从含义、设计和施工要求以及适用情况对5种常用的钢筋混凝土框架结构加固方法进行了介绍,具体包括增大截面加固法、外包型钢加固法、置换混凝土加固法、外加预应力加固法及增设支撑加固法。结合某地下车库框架柱加固工程实际,说明了该工程选择增大截面加固法的依据,详细介绍了该工程采用增大截面加固法的设计和施工过程。

In this paper, the reinforcement of reinforced concrete frame structure is described. Five commonly used reinforcement methods of reinforced concrete frame structure are introduced respectively from their meanings, design and construction requirements and application, which include the section increasing reinforcement method, the outsourcing steel reinforcement method, the replacing concrete reinforcement method, the external prestressed reinforcement method and the external support reinforcement method. Combined with a practical project, this paper explains the basis of choosing the method of increasing section reinforcement in this project, and introduces the design and construction process of the adopted method in detail.
