摘要
通过工程实例,在加固受力分析的基础上,提出了采用双侧预应力撑杆补强措施,并辅以套箍约束混凝土横向变形,从而既利用撑杆直接增加轴向受压承载能力,又利用套箍间接提高轴向受压承载能力。取得了施工方便,受力可靠。
Through the engineering example, based on the statical analysis of a reinforced concrete column strengthed, double side prestressing steel bar were used to strengthen the reinforced concrete columns aided with lateral tie to thus increased directly the strength of axial compression with the use of steel bar and increased indirectly the strength of axial compression with the use of lateral tie at the same time. The result is satisfactory, convenient to construct and economical.
