摘要
研究普通钢筋混凝土梁在开裂的情况下的预应力粘贴钢板的加固机理以及加固前后的受力性能,包括抗弯剪承载能力、开裂和刚度分析。作为对加固方法的一种新的尝试和探索,探究粘贴预应力钢板加固机理及其积极意义。
As an exploration of strengthening reinforced-concrete beam(RC-Beam),this paper combined the advantages of the methods of strengthening reinforced concrete beam with external prestress in gluing steel plate.Not only were the consolidate effect and mechanism of strengthening RC-Beam with external prestress in gluing steel plate discussed in this paper,but also strength,rigidity and advanced stress site of crack of RC-Beam were studied,which will be significant for strengthening RC-Beam.
