通过12根短木柱试件的试验研究,了解开裂、CFRP层数等对短木柱受力性能的影响。研究结果表明,开裂短木柱的承载力和极限位移均有明显降低;粘贴CFRP后,开裂短木柱的承载力和延性系数均有明显提高。通过粘贴CFRP不仅可明显改善开裂短木柱的受力性能,还可适当放宽对木柱材质等级的限制,增加木材的利用率。 Through the experimental study of 12 short-pillared wood specimens, the influence of cracking, the number of CFRP layers on the mechanical properties of short wood pillars was studied. The results show that both the bearing capacity and the ultimate displacement of the cracked short studs are obviously reduced. The bearing capacity and the ductility coefficient of cracked short studs are obviously improved after CFRP is affixed. By affixing CFRP, not only can obviously improve the mechanical properties of cracked short wooden columns, but also the restrictions on the grades of wooden columns can be appropriately relaxed to increase the utilization of wood.
