CFRP片材加固混凝土连续梁长期受力性能与极限承载力试验

摘要

Three rectangular cross-section concrete continuous beam were made, CFRP laminates strenghening, temperature, shrinkage and other factors were considered. The long-term creep behaviors were tested for 648 days, the ultimate bearing capacity of three beams were tested.%制作了3根钢筋混凝土矩形截面连续梁,考虑了CFRP片材加固、温度等因素影响,对3根梁进行长达648d的长期荷载试验,研究了长期荷载作用下的徐变性能,并对3根梁进行了极限承载力试验.
