摘要
本文通过钢筋混凝土芯梁及粘贴钢板补强混凝土复合梁的疲劳试验,研究了它们在疲劳试验过程中载荷和加载线位移及跨中挠度的变化规律。同时,还探讨了混凝土强度、补强钢板厚度等因素对粘钢补强梁的疲劳性能影响。
This paper deals with the load-deflection and load displacement curves of beams basedon the fatigue experiments of plated and unplated RC beams. At the same time, it presents the effects of concrete code and plate thickness on fatigue property of plated RCbeams.
