[V-620] An experiment on the cable break behavior of grout filled stay-cables

*小野 聖久1、服部 雅史1、野島 昭二2、立松 秀之2 (1. 中日本高速道路、2. 中日本高速技術マーケティング)

Keywords:cable-stayed bridge, stay cable, grout, tension decrease

In a stay-cable with a protective tube filled with grout, even if the wire corrodes and breaks, tension is transmitted to other wires through the grout.Therefore, the influence of the presence of grout on tension reduction was examined by experiments. As a result, it was confirmed that there was a drop in tension even with stay-cable filled with grout inside.
