Abstract

Penelitian ini meliputi analisis beban gempa, klasifikasi kategori desain seismik, dan pemodelan struktur. Analisis struktur dilakukan dengan menggunakan metode analisis dinamis dimana menggunakan metode ragam respons spektra guna mengevaluasi perilaku seismik bangunan. Gedung ini diklasifikasikan pada kategori klasifikasi desain seismik D, maka menggunakan Sistem Rangka Baja Pemikul Momen Khusus (SRPMK). Pada struktur dilakukan Analisis struktur guna pengecekan terhadap perilaku struktur yang mempengaruhi pusat kekakuannya. Perangkat lunak berbasis metode elemen hingga digunakan dalam pemeriksaan analisis struktu gedung ini. Beban aksial (beban mati dan beban hidup) dan beban lateral (beban angin dan beban gempa) yang diperhitungkan dalam analisis ini sesuai dengan SNI 1726:2019 berisi perencanaan ketahanan gempa dan SNI 1727:2020 berisi beban  minimum gedung. Hasil analisis menunjukkan bahwa balok, kolom, pelat lantai dan pondasi yang digunakan gedung ini mampu menahan beban aksial maupun beban lateral dengan penggunaan faktor skala gaya gempa, simpangan antar tingkat dan pengaruh P-Delta masih dalam batas ijin yang disyaratkan oleh peraturan yang berlaku. Sistem struktur memenuhi persyaratan kekuatan, kekakuan dan stabilitas terhadap gaya gempa yang terjadi di pontianak, sehingga dapat dirancang secara aman dan nyaman sesuai standar perencanaan. Kata kunci : Analisis struktur, Gedung kuliah terpadu, Beban gempa, Pontianak, Struktur beton bertulang

Abstract

Rapid infrastructure development demands reliable road pavement systems, especially on expansive and low-bearing capacity cohesive soils. This research investigates the addition of fins to pavement slabs as an innovative rigid pavement design. The study investigates how fins and their varying inclination angles 0°, 30°, 60°, 90° affect failure patterns and bearing capacity in cohesive soil. Tests on five slab types revealed distinct behaviors. Finless slabs and those with 90° fins showed shallow local shear failure. The 0° finned slab formed wedge failure due to stress concentration. Slabs with 30° and 60° fin inclinations exhibited a more distributed failure pattern with a wider plastic zone, indicating efficient stress distribution. The highest ultimate bearing capacity was achieved by 60° finned slab, reaching 10.60 kN, followed by the 30° finned slab at 6.20 kN. The 0° finned slab showed the bearing capacity at 3.53 kN. These significantly outperformed the finless slab at 3.40 kN and the 90° finned slab at 4.00 kN. These findings suggest that specific fin configurations can significantly improve slab performance on cohesive soil, offering a solution for problematic soil conditions in rigid pavement systems.
