EXPERIMENT ON THE BEHAVIOR OF DOUBLE-BALL ANCHORAGE IN PRESTRESSED CONCRETE SUBJECTED TO SUSTAINED LOADING
-
摘要: 通过对用于预应力混凝土的一种新型双压花锚具足尺寸试件的试验,研究这种锚具在持续荷载下的变形特点、不同持荷应力水平的影响以及锚具受持续荷载后的承载力等问题,并给出持续荷载阶段锚具变形计算的建议公式。Abstract: Full-size specimens of the double-ball anchorage system used in prestressed concrete structures were tested to investigate its behavior under sustained loads,its maximum load-carrying capacity and the influence of stress levels of sustained loads on its performance.The formula for estimating its deformation related to sustained loads is proposed.
