1. Seismic test of the device for energy absorption1. 1 Object of the testA test was conducted to investigate the structural performance of the PVA-HPFRCC reinforced wall type columns, which was planned as energy dissipating device. PVA-HPFRCC is Polyvinyl Alcohol (PVA) fiber reinforced mortal, the fiber volume fraction of PVA-HPFRSS used in this research is 1.5%. Main objective of the test is to investigate the damage tolerance in each shear stress level, the energy dissipation, and the stiffness control.1. 2 Outline of the testThe statical cyclic loading test with six device elements was conducted. The cross section in clear span of the device was 200mm in width, 450 mm in depth, and its span were set at 900, 600, 450mm. The stiffness and the shear stress level were designed by combining the yield strength of main bar and the shear span.1. 3 Result of the test(1) The ductility and the energy dissipation were upgraded by using PVA-HPFRCC in place of concrete. Further, in PVA-HPFRCC specimen, the crack was distributed and the width of crack is smaller than conventional RC specimen.(2) The stiffness and flexural capacity were controlled by combining the yield strength of main bar and the shear span. It mean that the device using PVA-HPFRCC absorb the energy from little deflection angle.Though this test, the PVA-HPFRCC reinforced wall type columns can use as energy dissipating device.2. Seismic response analysisForce-displacement hysteresys of the energy dissipating device using PVA-HPFRCC was modeled by statical loading test, and the seismic response analysis about RC structure with the device was conducted. The seismic response of RC structure was decreased by inserting the device using PVA-HPFRCC. As the result, it can be said that the energy dissipating device using PVA-HPFRCC useful to control the seismic response of the RC structure.

1. 能量吸收装置的抗震试验1试验对象通过试验研究PVA-HPFRCC加筋墙型柱的结构性能，并将其规划为消能装置。PVA- hpfrcc是聚乙烯醇（PVA）纤维增强材料，本研究使用的PVA- hpfrss纤维体积分数为1.5%。试验的主要目的是研究各剪应力水平下的损伤容限、能量耗散和刚度控制。2试验大纲进行了6个装置单元的静循环加载试验。装置的净跨截面宽度为200mm，深度为450mm，其跨度分别设置为900mm、600mm、450mm。结合主筋屈服强度和抗剪跨度进行刚度和剪应力水平的设计。(1)用PVA-HPFRCC代替混凝土，提高了混凝土的延性和耗能。PVA-HPFRCC试件裂纹分布较均匀，且裂缝宽度小于常规RC试件。(2)结合主筋屈服强度和抗剪跨度控制刚度和抗弯承载力。这意味着使用PVA-HPFRCC的装置从小的偏转角度吸收能量。通过本试验，PVA-HPFRCC加筋墙型柱可以作为消能装置。通过静载试验建立了PVA-HPFRCC消能装置的力-位移滞回模型，并对安装该装置的RC结构进行了地震反应分析。采用PVA-HPFRCC插入装置，降低了钢筋混凝土结构的地震响应。因此，PVA-HPFRCC消能装置对控制钢筋混凝土结构的地震反应具有重要意义。
