摘要
对使用无机锚固材料植筋连接的钢结构加层后的3层框架结构进行了拟静力抗震试验,并同增层节点采用碳纤维布加固补强后的拟静力试验进行对比分析。试验结果表明:使用无机锚固材料植筋连接并进行钢结构加层改造的框架结构具有较好的抗震延性,对增层节点进行碳纤维布补强后结构的整体抗震性能更为优越,塑性铰形成顺序更为合理,从而能够更好地满足加层结构的工程抗震要求。
The quasi-static seismic experiment on a three-adding-story steel frame structure strengthened by planting bar with inorganic anchoring material was carried out and compared with the strengthening method of carbon fiber sheet. The results indicate that the seismic ductility of the adding-story steel frame structure strengthened by planting bar with inorganic anchoring material is well but not better than that of structural joints strengthened by carbon fiber sheet. Structural joints strengthened by carbon fiber sheet have reasonable emerging sequence of plastic hinge and can satisfy the requirements of the engineering seismic performance of adding-story structures well.
