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

In this analytical study, a building structure planning analysis will be carried out as well as checking the beam structure for torsional loads at the ITB Sports Arena (GOR) Building located in Cirebon. Analysis and planning refer to SNI 1726:2019, SNI 2847:2019 and SNI 2020. Modeling analysis and checking of torsion beams using the SAP2000 program as well as manual calculation analysis. Torque is almost the same as design for bending and shearing when the factored torsional moment load applied to a section exceeds the torsional resistance that can be provided by the concrete section itself. The results of the analysis and calculation of the beam structure using the SAP2000 program were obtained: from reinforcement calculations and analysis using SAP2000 software on the beam structure, as well as checking the beam for torsion, the value was taken with the largest torsion force of 91.3673 KN for beam B1A (600 x 450): Top reinforcement with supports 5D22, field 3D22, Support 3D22 ; Bottom reinforcement with support 4D22, Field 4D22, Support 4D22; Web reinforcement with support 4D16, Field 4D16, Support 4D16; using 3 foot stirrups with support D13-100, Field D13-150, Support 13-100.

Abstract

Kekuatan kapasitas geser balok beton dapat ditingkatkan dengan penggunaan serat baja tipe ujung bengkok pada campuran beton. Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan serat baja dengan tipe ujung bengkok pada beton terhadap kapasitas geser balok beton bertulang. Pembuatan benda uji dibuat berupa balok bertulangan dengan/tanpa tulangan sengkang. Variabel-variabel yang digunakan : rasio air/semen (w/c = 0.50), dan volume serat (Vf) = 0.0%, 0.5%, 1.0% dan 2%. Hasil penelitian diperoleh bahwa kekuatan kapasitas geser balok yang diperkuat serat lebih besar daripada kekuatan balok beton polos dan cenderung meningkat seiring dengan penambahan serat baja pada kandungan beton seiring dengan peningkatan jumlah fraksi volume serat. Perbandingan data eksperimental dan model analisis kekuatan menunjukkan bahwa model analitis dapat memprediksi efek w/c, Vf, dan kontribusi tulangan baja longitudinal dan transversal secara memadai. Hasil beban ultimit yang diperoleh pada analisis model FE nilai gaya geser ultimit secara keseluruhan lebih rendah dibanding dengan hasil eksperimen. Bentuk pola keretakan/keruntuhan yang didapati hasil analisis model FE terlihat tidak jauh beda dengan hasil eksperimen.
