Analisis dan Perkuatan Kolom Baja Struktural Akibat Beban Gempa Menggunakan HBeam

Evaluation or study of existing building structures must consider the strength and stiffness structural components due to gravity loads earthquake loads. The strengthening Hbeam column structure is add steel plates column. This method a way improve performance in terms ease implementation, time cost when compared replacing adding new components. purpose this was analyze plate seismic Parameters analyzed were vibration period, lateral displacement internal forces research quantitative analytical research, where geometry data 3D frame portal determined independently, while material loading are based on (SNI 1727:2013) 1729:2019). modeled using finite element software, ETABS software. results analysis show that by which installed horizontally middle cross section with dimensions 15 mm thick 145 long (18.59% cross-sectional area column) increases 12.01% 14.2% respectively - for period drift, respectively. smaller than allowable drift ratio less 130%, so does not experience soft story. average maximum (moment, shear axial force) load reinforcement increased 12.50%, 9.68% 14.01% without along addition
