Abstract

Analisa elemen pelat terus berkembang sehubungan dengan semakin kompleksnya bentuk struktur. Menganalisa elemen pelat yang kompleks, peneliti menggunakan metode numerik, dalam hal ini metode elemen hingga. Metode elemen hingga sudah banyak digunakan dalam menganalisa pelat elemen, peneliti terus berlomba dalam mengembangkan elemen pelat dan cangkang yang dapat diaplikasi dalam berbagai kondisi dan mempunyai akurasi yang tinggi. Penggunaan elemen segitiga menarik perhatian peneliti karena simplisitas dan fleksibilitas dalam mendiskritisasi elemen yang kompleks. Elemen segitiga tiga nodal MITC3 (Mixed Interpolation of Tensorial Components) merupakan salah satu elemen pelat yang menggunakan elemen segitiga dan merupakan elemen pelat yang terkenal serta banyak digunakan oleh perangkat lunak komersial. Penelitian tentang elemen MITC3 sudah banyak dilakukan terutama dalam kasus statik, pada penelitian ini peneliti menganalisa elemen pelat isotropik MITC3 pada kasus tekuk yang diberi beban mekanikal berupa beban in-plane uniaksial dan biaksial. Penelitian ini bertujuan untuk melihat tingkat konvergensi elemen pelat isotropik MITC3 pada kasus tekuk, penelitian ini diawali dengan melakukan studi literatur, selanjutnya menguji kinerja dan prilaku konvergensi elemen pelat MITC3 pada kasus pelat persegi dengan memvariasikan rasio panjang terhadap tebalnya. Hasil analisa akan dibandingkan dengan referensi yang ada di literatur.

Abstract

The development of construction material that is more efficient and friendly continued by researchers. Steel is a material that is widely used in construction, especially hot-rolled steel, the use of cold-formed steel is an innovation where cold-formed steel has more advantages than hot-rolled steel. Many studies of cold-formed steel sections due to applied loads have been carried out to observe the behavior and capacity of the sections. An unlipped channel is a steel section that can be used in buildings, cold-formed steel unlipped channel will be subjected to an axial load to see the behavior and capacity of the section which is the aim of this study. In this study, a numerical analysis of cold-formed steel sections will be performed using the finite element method through ABAQUS software, the numerical analysis is committed based on existing research in the literature. The Sectional capacity resulting from the numerical analysis will be compared with the effective width method approach based on SNI 7971-2013.

Abstract

Steel building structures must be designed to safely and efficiently resist gravity and lateral loads. One of the key factors influencing structural performance is the shape and type of column section used, as differences in geometric characteristics affect stiffness, strength capacity, and structural response to lateral loads, particularly seismic forces. This study aims to analyze the effect of using King Cross, Tube, and Wide Flange sections as columns in steel building structures on overall building performance under gravity and lateral loads. Structural modeling was carried out using ETABS software by developing three building models with identical configurations, dimensions, and loading conditions, differing only in the type of column section applied. All models were designed using a Special Moment Resisting Frame (SMRF) system. The results indicate that variations in column section types significantly influence structural performance, where sections with higher stiffness produce smaller inter-story drift and better lateral load response. Furthermore, differences in column sections affect the fundamental period of vibration, internal forces, and strength ratios of structural elements, which in turn impact the efficiency and safety level of steel building structures. These findings are expected to provide useful guidance for structural engineers in selecting the most suitable column section for a given design requirement.Keywords: steel column, King Cross, Tube, Wide Flange, ETABS, inter-story drift, SMRF
