【摘要】：粘贴纤维复合材加固法和粘贴钢板加固法以其施工操作简单、工期短、加固后对使用空间影响小等优点被广泛应用于各类受弯构件的加固中。而且对于大偏心受压构件,《混凝土结构加固设计规范》(GB 50367—2013)也允许采用粘贴纤维复合材加固法和粘贴钢板加固法进行加固。然而工程中常用的PKPM、YJK等结构计算分析软件仅仅给出了混凝土柱的轴压比,而未给出混凝土柱是属于大偏心受压柱还是属于小偏心受压柱。如果想采用粘贴纤维复合材加固法和粘贴钢板加固法对混凝土柱进行加固设计,就需要设计人员手工计算各个混凝土柱是否属于大偏心受压柱,这样无疑会增大很多工作量。为此,本文就混凝土柱的轴压比和大偏心受压的关系进行了推导,以方便设计人员在工作中使用。
[Abstract]:The reinforcement method of bonded fiber composite material and steel plate paste method are simple in construction operation and short in construction period. The advantages such as little influence on service space after reinforcement are widely used in the reinforcement of all kinds of flexural members. Moreover, for large eccentric compression members, the concrete structural strengthening Design Code (GB50367-2013) also allows the use of bonded fiber composite materials for reinforcement. However, the structural calculation and analysis software such as PKPMYJK, which is commonly used in engineering, only gives the axial compression ratio of concrete columns. But it is not given whether the concrete column is a large eccentric compression column or a small eccentric compression column. It is necessary for designers to calculate manually whether each concrete column belongs to a large eccentric compression column, which will undoubtedly increase the workload. Therefore, the relationship between axial compression ratio and eccentric compression of concrete column is deduced in this paper. To facilitate the use of designers in the work.
