Abstract

The seismic behaviors of interior frame joints composed of wasted fiber recycled aggregate concrete were studied experimentally. The effects of certain design parameters such as the length and volume ratio of wasted fiber with a constant replacement rate of recycled aggregate on the anti-seismic performance of the frame were investigated,5 full-scale specimens were designed and fabricated,then cyclic loading tests were conducted. In the tests,the replacement rate of recycled aggregate was kept at 50%,the wasted fiber length was 12 mm,19 mm,30 mm and volume content was 0.08%,0.12% and 0.16% respectively. The failure mode,hysteretic property,ductility,energy dissipation characteristics and other issues of frame joints were analyzed with different wasted fiber lengths and volume contents. The experimental results show that the destruction of wasted fiber recycled concrete frame joints experience four stages,they are initial cracking,thorough cracking,ultimate stage and failure stage. With the fiber length of 19 mm and volume content of 0.12%,the wasted fiber recycled concrete beam-column joint has better seismic behaviors. Compared with the wasted fiber length,the volume of wasted fiber content has greater influence on the seismic performance of beam-column joints. A shear strength calculation formula for wasted fiber recycled aggregate concrete was put forward. The calculation results coincide well with the test results.
