【摘要】 设计制作了4个弧形预应力混凝土肋柱整体式声屏障,进行了低周反复荷载试验,研究了等截面弧形和变截面弧形整体式预应力混凝土声屏障的破坏形态、变形恢复能力、延性和耗能能力等抗震性能。试验结果表明,整体式预应力混凝土声屏障的滞回曲线比较饱满,表现出了较大的位移延性、良好的耗能能力和变形恢复能力,总体抗震性能优良。更多还原

【Abstract】 Four specimens of arc type prestressed concrete noise barrier with rib column specimens were designed and manufactured.The seismic performance of the specimens were investigate by low cyclic loading test,such as failure patterns,displacement restoring capacity,ductility,energy dissipation capacity,etc.The results show that all specimens behave better seismic performance, presenting fuller hysteresis loops and relatively high displacement ductility,energy dissipation capacity and displacement restoring capacity.更多还原
