Abstract

Komponen non-struktural adalah salah satu komponen pelengkap sebuah bangunan yang dalam perencanaan sering hanya dianggap sebagai beban mati saja, tanpa melihat interaksi yang dapat ditimbulkan terhadap komponen struktural. Penelitian ini dilakukan untuk mengetahui perubahan respons struktur suatu bangunan yang diakibatkan oleh kontribusi dari komponen non-struktural. Model gedung yang dianalisis berupa gedung persegi dengan 10 lantai dengan ukuran 20 m x 20 m. Model gedung tersebut terdiri atas 5 variasi yaitu 1 model bangunan tanpa pengaruh komponen non-struktural (model S-NS0) dan 4 model bangunan dengan pengaruh komponen non-struktural (model S-NSIB, model S-NSACB, model S-NSBM, dan model S-NSB). Analisis ini dilakukan dengan memberikan beban dorong lateral (pushover) menggunakan software ETABS. Hasil analisis yang diperoleh adalah terdapatnya penurunan respons struktur yang dihasilkan dari bangunan tanpa komponen non-struktural ke bangunan dengan pengaruh komponen non-struktural. Besarnya penurunan yang terjadi mencapai angka 87,17% untuk respons gaya geser balok, 85,39% untuk momen tumpuan kiri, 91,30% untuk momen tumpuan kanan, 41,66 % untuk momen lapangan, 83,81% untuk lendutan balok, 41,23% untuk gaya geser kolom, 33,03% untuk gaya aksial kolom, 93,60% untuk momen maksimal kolom, dan 63,67% untuk perubahan drift total bangunan.

A non-structural component is one of the supporting elements of a structure that is frequently only taken into account as a dead load during planning. This study was carried out to identify changes in a building's structural response brought on by contributions from non-structural elements. The building is modeled as a square structure with ten stories and a 20 m × 20 m span. The building model consists of 5 variations, namely 1 building model without the non-structural components (model S-NS0) and 4 building models with the non-structural components (model S-NSIB, model S-NSACB, model S-NSBM, and model S-NSB). This analysis was performed by providing a pushover using ETABS software. The findings are, there is a decrease in the reaction of structures when comparing buildings with and without the influence of non-structural components. The magnitude of the decline reached the figures of 87.17% for the beam shear force response, 85.39% for the left pedestal moment, 91.30% for the right fulcrum moment, 41.66% for the field moment, 83.81% for the beam deflection, 41.23% for the column shear force, 33.03% for the column axial force, 93.60% for the column maximum moment, and 63,67% for the total drift change of the building.
