中文摘要：
针对现在大量仿古建筑的出现,以及汶川地震后很多木结构出现轻微破坏,需要加固维修,木材运用到建筑结构中的情况越来越多。采用AFRP纤维布加固7根短方木柱,探讨短方木柱的破坏形式。考察全包、间隔包裹、纤维层数对木柱性能的影响。试验表明:加固后木柱的承载力、刚度和延性均得到提高,在所有试件中全包2层AFRP试件的承载力及变形性能提高最大。随着纤维层数的增加,承载力提高与包裹层数之间不是正比关系,加固层数增加到3层承载力提高幅度开始下降。并且纤维复合材料加固木柱并不能改变木柱脆性破坏的形式。在所有试件中,由于其中一跟木柱有木结存在,所以其承载力强度降低很大,我们不加入木柱的计算中,后续应该做一些针对木结加固的试验。本文对加固木柱极限承载力进行理论分析,与已有的理论公式比较,建立木柱承载力的公式,并回归系数,与试验结果符合良好,为以后的工程实践提供参考。
