To study the seismic performance of embedded polyvinyl chloride (PVC) pipe confined reinforced high-strength concrete (PVC-RHC) columns, five specimens are designed for cyclic loading test, which include three PVC-RHC column specimens, an embedded circle steel tube confined reinforced high-strength concrete (CST-RHC) column specimen, and a reinforced high-strength concrete (RHC) column specimen. The failure mechanism and morphology are revealed by experiments. The influences of PVC pipe diameter, axial compression ratio, and concrete strength on seismic performance indexes are analyzed. The research results indicate thhe following: all specimens displayed shear baroclinic failure. Compared with RHC specimens, the hysteretic curves of the PVC-RHC specimen and CST-RHC specimen were fuller; furthermore, their energy dissipation capacity, deformation, and ductility were more beneficial. With the increase of the diameter–length ratio and axial pressure, the energy dissipation capacity and deformation capacity of PVC-RHC specimens decreased. The shear bearing capacity of the PVC-RHC specimen calculated with “concrete structure design code” (GB 50010-2010) was smaller than the test results by 25%, showing an excessive safety margin. Thus, according to the failure mechanism of the PVC-RHC specimen, a new calculation formula of shear bearing capacity is deduced, which is in good agreement with the experimental results.

Beton adalah material komposit (gabungan) dari partikel-partikel agregat yang saling mengikat menjadi suatu badan atau bagian yang solid dengan ikatan dari material semen. Beton juga dikenal dengan material dengan kekuatan tekan yang memadai, mudah dibentuk, mudah diproduksi secara local, relative kaku, dan ekonomis. Namun di sisi lain, beton juga menunjukan banyak keterbataan baik dalam proses produksi maupun sifat-sifat mekaniknya, sehingga beton pada umumnya hanya digunakan untuk konstruksi dengan ukuran kecil dan menengah.Abu sekam padi dihasilkan dari pembakaran sekam padi. Belakangan ini banyak peneliti yang memanfaatkan abu sekam padi dalam suatu bahan seperti pembuatan keramik, pembuatan batu bata, dan lain-lain.Penggunaan tulang hewan dalam penelitian kami adalah sebagai penambahan agregat kasar dalam pembuatan beton. Hal ini dikarenakan jumlah limbah tulang hewan di Indonesia yang sangat banyak dan belum termanfaatkan secara menyeluruh, Dengan beton mutu tinggi dimensi dari struktur dapat diperkecil sehingga berat struktur menjadi ringan. Hal tersebut menyebabkan beban yang diterima pondasi secara keseluruhan menjadi lebih kecil pula. Jika ditinjau dari segi ekonomi hal tersebut tentu akan lebih menguntungkan. Beton mutu tinggi dapat diartikan sebagai beton yang berorientasi pada kekuatan yang tinggi (high strength concrete) yang mempertimbangkan keawetan (durability) beton serta kemudahan pengerjaan beton (work-ability). Kata Kunci  ;   Beton Komposit , Abu Sekam, Penggunaan Tulang dan Beton Mutu Tinggi
