Abstract

The behavior of buildings with a masonry earthquake resisting system using the Spectrum Response method based on SNI 1726:2019 and 2847:2019, analysis was carried out on structures without walls and brick walls of 3-story buildings that function as residential homes in Jayamandala, South Jakarta. Building in Risk Category II, earthquake priority factor (Ie) is 1, medium soil site class (SD), design spectral 0.626 g and  0.505 g, seismic design category D, site response modification coefficient R for without walls 3 and walls 1 .5. Design period  0.437 seconds, static base shear force in x and y directions without walls 1239.66 kN and walls 2479 kN. The analysis results show that mode 1 without walls is 1.675 seconds and walls are 0.441 seconds, the equivalent shear force in x and y directions without walls is 2284.35 kN and walls is 2478.83 kN, the dynamic earthquake shear force in x and y directions without walls is 2284.36 kN and walls 2479 kN, drift limit drift limit between floors without walls 94 mm and walls 32.9 mm,  stress is 45.357 N. Based on the results of structural behavior analysis of masonry earthquake resisting systems, without walls is more flexible than stiffer walls.

Abstract

Individu yang terlibat dalam kegiatan proyek konstruksi disebut sebagai tenaga kerja konstruksi. Menurut Pasal 70 Undang-Undang No. 02 Tahun 2017 tentang Jasa Konstruksi, setiap tenaga kerja konstruksi yang bekerja di bidang jasa konstruksi harus memiliki sertifikat kompetensi kerja (SKK). SKK ini diperoleh dengan melakukan uji kompetensi sesuai dengan Standar Kompetensi Kerja. Adanya kesenjangan antara kebutuhan dan tenaga kerja konstruksi yang memiliki SKK terlihat jelas, sehingga mendorong penulis untuk melakukan kajian ini. Studi ini bertujuan untuk mengetahui bagaimana sikap tenaga kerja konstruksi berperilaku terhadap sertifikasi kompetensi kerja di Jawa Barat. Penelitian dilakukan dengan menggunakan kuesioner dilakukan terhadap 92 responden dari semua pemangku kepentingan di sektor konstruksi. Hasil menunjukkan bahwa tanggapan responden terhadap penerapan sertifikasi kerja konstruksi positi dan baik, artinya responden memandang bahwa SKK penting untuk meningkatkan kompetensi dan profesionalisme pada tenaga kerja konstruksi.

Abstract

This study evaluates the structural performance of a five-story production building of PT. Mega Lifesciences, consisting of a steel frame system with a reinforced concrete roof slab, located in Bogor City. The building is classified as risk category II with a soft soil site class. Seismic analysis was carried out using the response spectrum method in accordance with SNI 1726:2019, while the structural performance evaluation was conducted through nonlinear static pushover analysis using the FEMA 440 Equivalent Linearization procedure based on ASCE 41-23. The objective of this research is to determine the performance level of the building by identifying the plastic hinge formation mechanism in bracings, beams, and columns, as well as examining the relationship between base shear and displacement in the pushover and seismic demand curves. The pushover analysis results indicate that in the X direction, the structure reaches a performance point classified as Damage Control at the coordinate (V; D) = (22,724.51 kN; 85.87 mm), while in the Y direction, the performance point is obtained at (V; D) = (24,400.23 kN; 71.19 mm). These findings indicate that the structure experiences damage but remains capable of maintaining its stability under seismic loading.
