Abstract

All of high-rise buildings should have sufficient stiffness the structure  will existed when earthquake occurred. The addition of shear wall structure and concentrically single bracing are alternative way to increase stiffness of the structure. This research is comparating the natural period of the structure with variation of stiffener structure between shear wall structure and concentrically single bracing by taking a case study at Mataram City Apartments and Condominium, Yogyakarta. The building consists of two towers and every tower consist of 18 stories. Analytical calculations in this research based on technical data field, quality of materials, and the results of structural analysis with numerical program. The calculation based on SNI 03-1726-2002, SNI 03-1726-2012, and the Uniform Building Code (UBC) 1997 Chapter 16 on Requirements Design Structure. Three modification of the shear wall layouts in this research are use to understanding about the effect of adding shear walls and concentrically single bracing to the natural period structure. Based on the calculation, the structure has adequate capacity to support the load with the natural period of 1.83 seconds. Maximum allowable vibration time by SNI 03-1726-2002 is 3.24 seconds, SNI 03-1726-2012 is 2,59 seconds, while the Uniform Building Code (UBC) is 1.68 seconds. So, the natural period requirement for this structure is 1.68 seconds. From all models, only the last model which have sufficient stiffness with natural period that 1.66 seconds for shear wall and 1.67 for concentrically single bracing stiffener.

Abstract

The structure of high-rise buildings should have sufficient stiffness so that no damage could harm users when earthquake occurred. The addition of shear wall structure is one way to increase stiffness of the building. This research is analyzing the capacity of structural elements and the influence of shear walls in high rise buildings, taking a case study at Mataram City Apartments and Condominium, Yogyakarta. The building consists of two towers. Analytical calculations in this research based on technical data field, quality of materials, and the results of structural analysis with SAP2000. After that, this research will calculate strength of the structure. The analysis based on SNI 03-2847-2002, SNI 03-1726-2002, and the Uniform Building Code (UBC) 1997 Chapter 16 on Requirements Design Structure. Three modification of the shear wall layouts in this research are use to understanding about the effect of adding shear walls to the natural vibration time.   Based on the analysis and calculation, the structure has adequate capacity to support the load with the natural vibration period of 1.831 seconds. Maximum allowable vibration time by SNI 03-1726-2002 is 3.24 seconds, while the Uniform Building Code (UBC) is 1.698 seconds. First model can decrease the natural vibration period of 1.53 % to 1.80 seconds with a drift reduction of 11.35 % in the x axis and 35.27 % in y axis. The second model can decrease the natural vibration period by 5.08 % to be 1.73 seconds with drift reduction is 20.73 % the x axis, 39.31 % and y axis. The merged models have the natural vibration structure of 1.66 seconds

Abstract

Beton merupakan suatu material yang banyak digunakan dalam dunia konstruksi. Namun, setiap produksi beton menimbulkan dampak buruk pada pemanasan global. Semen sebagai bahan pengikat beton dapat menyumbang emisi CO2 sebanyak 8% dalam setiap produksinya. Proses pengecoran pada beton juga dapat menghasilkan polusi suara akibat penggunaan alat vibrator. Para peneliti terus berupaya menghasilkan beton yang lebih ramah lingkungan. Self Compacting Geopolymer Concrete (SCGC) merupakan kombinasi baru antara beton geopolimer dan Self Compacting Concrete (SCC) yang masih terus diteliti dan dikembangkan hingga saat ini. SCGC merupakan beton ramah lingkungan karena tidak menggunakan semen portland sebagai bahan pengikatnya. Penggunaan beton SCGC tidak memerlukan vibrator karena memiliki sifat flowability yang baik. Penelitian ini menggunakan bahan pengikat berupa material pozzolan yang mengandung senyawa kimia berupa SiO2 dan Al2O3. Tahapan penelitian ini dilakukan dengan mencari metode curing dan mix design optimal dalam penyusunan SCGC. Pengujian XRF perlu dilakukan dalam penelitian ini untuk mengetahui kandungan senyawa kimia pada fly ash Tjiwi Kimia. Beberapa pengujian beton segar SCGC diperoleh hasil berupa slump flow 690 mm, T50 2,4 detik, v-funnel 8,35 mm, dan rasio l-box 0,84. Sifat mekanik beton diuji berdasarkan kuat tekan, kuat tarik belah, dan kuat lentur dengan hasil rata-rata sebesar 27,05 MPa, 6,32 MPa, 1,91 MPa.

Abstract

Building maintenance is vital to ensure facility reliability, security, and investment value, as neglect can lead to structural decay and safety hazards. This study aims to assess the deterioration level of sports facilities at PT SIER and devise an efficient maintenance plan. The process involves identifying structural damages, evaluating deterioration following guidelines, and planning maintenance actions. Subsequent steps include budgeting, creating Work Plans and Specifications, estimating Domestic Component Levels, and scheduling using the S-Curve. Analysis reveals varying degrees of architectural degradation, ranging from 1 to 3, signifying serious damage. The estimated total cost for upkeep and development is Rp 255,718,000, with a projected minimum Duty and Customs Levies value of 30.43%. Maintenance duration is estimated at 45 days, managed using the S-Curve method.
