Abstract
ABSTRAKSI Akibat gaya prategang yang diberikan pada struktur akan terjadi pemusatan gaya yang besar pada daerah angkur. Secara teoritis perhitungan tegangan yang terjadi pada endblok cukup rumit, sehingga diperlukan suatu metode yang mudah diaplikasikan guna mendaptakan pola distribusi tegangan yang terjadi pada endblock, sehingga prediksi dari prilaku struktur dapat diketahui dengan baik.Pada skripsi ini analisis elemen hingga linear dengan program SAP 2000 diguanakan untuk menyelidiki Endblock dengan penampang persegi. Analisis dilakukan berdasarkan tiga konfigurasi pemberian gaya prategangan yaitu konfigurasi angkur tunggal konsentris, angkur tunggal eksentris serta konfigurasi multi angkur (konsentris dan eksentris). Pengaruh beberapa parameter seperti rasio pengangkuran dan eksentrisitas diselidiki. Hasil analisis direpresentasikan dalam bentu grafis dan numerik untuk menggambarkan prilaku endblock terhadap beberapa parameter yang diberikan. Kata kunci : Beton Prategangan pascatarik, Endblock, Elemen Hingga, angkur tunggal, multi angkur. v ABSTRACT The effect of prestressing force is causing stress concentration in the edge of prestress concrete girder. Theoretically calculation of stress distribution in anchorage zone is complicated enough. So that it needed an easy method which is applicable to get the stress distribution value and pattern in anchorage zone. Trough this method we can predict the behaviors in anchorage zone. In this thesis finite element method under SAP 2000 program is used to investigate the anchorage zone with rectangular section. Analysis conducted into two configurations there are single anchorage and multiple anchorages. Influence of some parameter such as anchorage plate ratio, and eccentricity are investigated. The result is represented in graphical and numerical to describe the anchorage zone to some given parameters. Keywords : Posttensionned prestress concrete, anchorage zone, Finite Element Method, single anchorage, multiple anchorages
