Abstrak
Sambungan pelat ujung (end plate connection) adalah sambungan semi kaku yang secara umum digunakan untuk menghubungkan balok-kolom. Salah satu alternatif untuk meningkatkan kapasitas lentur sambungan adalah memperluas area sambungan pelat ujung. Namun, upaya yang dilakukan tersebut butuh dievaluasi lebih lanjut. Penelitian ini bertujuan untuk menginvestigasi kuat lentur sambungan pelat ujung dengan memberikan beberapa perkuatan yaitu penambahan area sambungan, pemasangan pengaku pelat badan, dan perpanjangan penyokong di area bawah balok. Untuk mengevaluasi signifikansi perkuatan, benda uji tanpa perkuatan (ordinary end plate connection) digunakan sebagai acuan. Penelitian dilakukan melalui pemberian beban geser yang ditempatkan pada 400 mm dari sambungan dan beban ditingkatkan secara bertahap hingga benda uji gagal. Kajian eksperimental menunjukkan benda uji dengan kombinasi perkuatan berupa penambahan area sambungan dan penambahan pengaku badan memberikan kuat geser dan lentur yang paling baik. Kajian teoritis mengacu ke SNI 03-1729-2020 menunjukkan kuat lentur nominal lebih kecil dibandingkan kuat lentur eksperimental. Hal ini menunjukkan kajian teoritis memberikan kuat lentur lebih konservatif.

Abstract
An end plate connection is a semi-rigid connection used to connect a beam to a column. One alternative to improve the flexural strength is to enlarge the end plate connection area. However, this strengthening approach needs to be more specifically investigated. This study aims to evaluate the flexural strength of the connections by several strengthening methods: enlarging the connection area, installing web stiffeners, and lengthening the haunch at the bottom side of the beam. To examine the significance of strengthening approaches, an un-strengthened specimen (ordinary end plate connection) was considered as the reference. The research work was first carried out by positioning the shear load at a distance of 400 mm from the connection area, and it was gradually increased until the specimens failed. The experimental study also revealed that the specimen strengthened by combining an enlarged connection area and web stiffeners performed the best in terms of shear and flexural strength. The theoretical study referring to the SNI 03-1729-2020 demonstrated the nominal flexural strength, which is smaller than the experimental flexural strength. This behavior showed that the theoretical study provided more conservative flexural strength.
