ABSTRAKSI
Penelitian ini merupakan penelitian eksperimental perilaku siklik balok beton prategang parsial
pratarik. Subyek penelitian adalah dua spesimen balok yang dibebani secara kuasi-statik bolakbalik
di tengah bentang. Variabel utama adalah perbandingan luas tulangan tarik dan tekan.
Pengujian menghasilkan indikasi bahwa untuk perbandingan luas tulangan yang sama akan
mendapatkan disipasi energi yang berbeda antara arah tekan dan arah tarik karena bagian tekan
diperkuat oleh tendon prategang.
Kata kunci : balok beton prategang parsial, beban kuasi statik bolak balik
ABSTRACT
The research described herein is an experimental study of the cyclic behaviour of partial
prestressed concrete beams. Two different beams were tested by quasi-static cyclic loading.
Beams were reinforced with the same areas of compression and tension steel but different in
moment ultimate for positive and negative directions due to the existence of prestressing
reinforcement at the bottom side of the section.
The results for these beams showed a different cyclic behaviour at each direction of loading.
The other beams were designed with similar ultimate moment capacity both for positive and
negative directions by using different reinforcement. At the bottom side, the beams were
reinforced using ordinary reinforcing bars and pre stressing strand while the top side was
reinforced by reinforcing bars only with larger area compared to reinforcing bars in the bottom
side. For these beams, the result showed that, the different among the hysteretic curves on
positive and negative loading were insignificant.
Keywords : partial prestressed concrete beam, quasi-static cyclic loading
