摘要
进行了 5根简支体外预应力钢与混凝土组合梁在竖向荷载下的试验研究。对比分析了普通钢与混凝土组合梁、预应力钢与混凝土组合梁和预应力加固钢与混凝土组合梁的受力性能与破坏形态。
Five prestressed steel & concrete composite beams are tested under vertical load.The failure modes and the mechanical behaviors of the common steel & concrete composite beam and the prestressed beam and the strengthened beam are analyzed and compared.
