The column, which is the vertical main structural part of the building, bears the force transmitted from the upper beam and slab and is a crucial part of the structure. In this study, the columns with a rectangular section cut from poplar were reinforced by basalt fiber-reinforced polymer (BFRP) strips with four different reinforced configurations. The mechanical behaviors of the specimens were also investigated under different eccentricities. Experimental results are presented as follows: for the wooden columns under axial compression, the wooden column BFRP with one layer spaced apart, two layers spaced apart, one layer fully filled, and two layers fully reinforced demonstrated increased bearing capacities of 3.13%, 30.00%, 40.63%, and 65.00%, respectively; the longitudinal strain increased by 7.54%, 19.65%, 22.06%, and 30.69%, and the lateral strain decreased by 26.53%, 29.80%, 41.30%, and 66.64%, respectively. Meanwhile, for the wooden column subjected to eccentric compression, the bearing capacities of the aforementioned wooden column BFRP configurations increased by 8.70%, 19.56%, 23.91%, and 30.43%; the longitudinal strain of the wooden column increased by 25.41%, 35.20%, 39.52%, and 41.85%; and the transverse strain increased by 130.77%, 166.77%, 192.57%, and 230.86%. In addition, the finite element model was used to simulate the eccentric compression behavior of the specimen. However, the ultimate bearing capacity and deflection of the analyzed column were higher than the test value. This finding was due to the completely ideal state of poplar in Finite Element Analysis (FEA) modeling without the influence of some initial defects, such as knots. These values can roughly be used as a reference for experimental results for the repair and reinforcement of poplar structures in Xinjiang.

BFRP加固的长杨杨圆柱的偏心受压性能

圆柱是建筑物的垂直主要结构部分，承受从上梁和楼板传递的力，是结构的重要组成部分。在这项研究中，从杨树上切下矩形截面的柱子用玄武岩纤维增强聚合物（BFRP）板条进行了增强，该板条具有四种不同的增强结构。还研究了在不同偏心率下样品的力学性能。实验结果如下：对于轴向受压的木柱，一层隔开，两层隔开，一层完全填充，两层完全加固的木质柱BFRP的承载力提高了3.13％，30.00％ ，分别为40.63％和65.00％；纵向应变分别增加了7.54％，19.65％，22.06％和30.69％，横向应变分别降低了26.53％，29.80％，41.30％和66.64％。同时，对于经受偏心压缩的木柱，上述木柱BFRP构型的承载力增加了8.70％，19.56％，23.91％和30.43％；木柱的纵向应变分别增加了25.41％，35.20％，39.52％和41.85％。横向应变分别增加了130.77％，166.77％，192.57％和230.86％。另外，有限元模型被用来模拟样品的偏心压缩行为。但是，分析柱的极限承载力和挠度高于测试值。这一发现是由于有限元分析（FEA）建模中杨树的完全理想状态而没有一些初始缺陷（例如打结）的影响。
