Abstract

The truss structure of the bridge is formed from several arrangement of rod elements which are connected by joint joints at the point of connection. The actual conditions in the field on the main frame structure of the Way Mamua bridge, Leihitu District, Central Maluku Regency, have dimensions of the steel cross-section that are quite large and not optimal, so that in this present study aims to analyze the rod forces of the Way Mamua Bridge structure and optimize the cross-sectional dimensions of the Way Mamua Bridge trunk frame. The methods used in this study are the ritter and cremona methods, as well as cross-sectional optimization simulations using the help of the SAP2000 program. Loading Standards for Bridges based on SNI 1725:2016 and Steel Structure Planning Standards for Bridges are used by SK regulations. SNI T-03-2005. Based on the results analysis of the rod forces of the Way Mamua Bridge structure, a minimum bar force was obtained for the upper horizontal bar, the lower horizontal bar and the diagonal bar totaling 2 bars. The maximum bar force for the upper horizontal bar is 1 bar, while the lower horizontal bar and diagonal bar are 2 bars with accepted forces namely compressive and tensile forces. The optimization results obtained an increase in the percentage of cross-sectional dimensions to the cross-sectional area for the upper horizontal bar by 2%, the lower horizontal bar and diagonal bar experienced a percentage reduction of 64% and 54% of the cross-sectional dimensions under actual conditions in the field. From the optimization results, the voltage ratio is not > 1 so that it can be concluded that the bridge bar truss structure is still in safe condition.

Abstract

The foundation of the RTMC Polda Maluku building has changed in the length of the piles used during implementation that is not in accordance with the plan, raising the question of whether the pile foundation with its carrying capacity is able to accept the load working on it. The purpose of this study is to obtain the results of calculating the carrying capacity and lowering of pile foundations in the RTMC building of the Maluku Regional Police using the Meyerhoff method based on Sondir test result data, SPT and laboratory test result data. This study shows that the calculation of the ultimate carrying capacity obtained the ultimate carrying capacity value of single piles from sondir data of 305.6 tons, and SPT data of 595.2 tons and laboratory data of 150.88 tons. This shows that the largest carrying capacity results are based on SPT data, then followed by sondir data and the smallest is the carrying capacity based on laboratory data results. The calculation of the decline in the pile foundation with the number of 2 piles shows a single decrease of 0.0062 m and a decrease in the pile group of 0.015 m and the result of the decline in the pile foundation with a total of 3 piles shows a single decrease of 0.0063 m and a decrease in the group of 0.015 m. This shows that the decrease in the foundation of 2 poles and 3 poles is smaller than the allowable decrease of 0.15 m so that the decrease is declared safe.

Abstract

Central Maluku Regency is an area prone to earthquakes because it is included in one of the 5th earthquake zone areas in Indonesia, so it is very necessary to analyze the performance of structures against earthquakes. The purpose of this research is to produce the displacement value between floors in the upper structure of the Central Maluku Regency DPRD Building and obtain the performance of the upper structure of the Central Maluku Regency DPRD Building with non-linear static analysis with the help of the SAP2000 v.22 program. This research shows several conclusions.  The displacement value between plants due to the largest X-direction earthquake load is 21.19 mm, and the largest Y-direction displacement is 20.73 mm. Evaluation of structural performance The results of the X-direction review capacity curve show that the building is included in the IO condition, while the Y-direction review provides an overview of the behavior of the structure experiencing elastic, in-elastic conditions and then experiencing collapse shown by the curve with a decrease. In the Y direction, the building is included in the IO condition. The design concept of a strong column weak beam is fulfilled, this is because, in the structural elements of the building, the beam experiences plastic conditions earlier than the column.

Abstract

Tulangan yang digunakan untuk balok beton pada saat ini umumnya berupa tulangan geser atau sengkang dipasang secara tegak lurus terhadap sumbu balok. Gagasan yang melatari tajuk permasalahan ini timbul dari hasil pengamatan penulis terhadap penggunaan tulangan sistem rangka balok beton bertulang dengan mengubah konfigurasi tulangan geser vertikal menjadi tulangan miring yang kurang akan teori terkait penggunaannya. Penelitian ini bertujuan untuk menganalisis kapasitas momen lentur balok beton tulangan sistem rangka dan menghasilkan persamanaan teoritis momen lentur penahan tulangan sistem rangka. Penelitian ini merupakan penelitian ekeperimental laboratorium dengan rancangan benda uji sebanyak dua belas  benda uji yang terdiri dari tiga balok normal (BN) sebagai balok variabel kontrol dan sembilan balok tulangan sistem rangka (BTR) sebagai variabel bebas. Data dianalisis dengan menggunakan metode kekuatan (strength design method). Hasil penelitian menunjukan bahwa penggunaan tulangan sistem rangka meningkatkan kekuatan balok pada saat mencapai beban ultimit terhadap kapasitas lentur dengan momen penahan rangka MPF pada balok BTR25 sebesar 10,23%, balok BTR50 sebesar 7,47% dan balok BTR75 sebesar 4,60%.

Abstract

Penyelidikan defleksi telah dilakukan sebelum tahun 1970-an dan analisisnya memberikan batasan tegangan beton sekitar 45% dari kekuatan tekannya dan tegangan baja 50% dari kekuatan lelehnya pada balok beton bertulang. Pada umumnya balok beton bertulang menggunakan tulangan sengkang dipasang secara tegak lurus terhadap sumbu balok guna menahan kekuatan gaya geser. Perubahan geometrik tulangan sistem rangka dapat meningkatkan kekuatan geser dan kekuatan lentur serta mengurangi besarnya defleksi pada balok. Oleh pengamatan penulis, bagaimana perilaku defleksi balok beton dengan mengubah konfigurasi tulangan geser vertikal menjadi tulangan miring. Pada penelitian ini bertujuan untuk menganalisis perilaku defleksi balok beton tulangan sistem rangka dengan jarak spasi seperempat dari tinggi efektif balok. Penelitian ini merupakan penelitian ekeperimental laboratorium dengan rancangan benda uji sebanyak enam benda uji yang terdiri dari tiga balok normal (BN) sebagai balok variabel kontrol dan tiga balok tulangan sistem rangka dengan jarak spasi 0,25d (BTR25) sebagai variabel bebas. Data dianalisis dengan menggunakan metode kekuatan (strength design method). Hasil penelitian menunjukan bahwa perilaku defleksi balok beton tulangan sistem rangka dengan jarak spasi seperempat dari tinggi efektif balok (BTR25) mempunyai kemampuan layan (serviceability) lebih baik dan meningkatkan kapasitas lentur balok Mu hingga 10,23% serta dapat mengurangi besar lendutan dari balok BN.

Abstract

In Construction Project Management studies, it is essential to analyze and assess the stability and strength of building structures to determine their ability to resist applied loads. In the construction project of the Integrated Educational Building of IAIN Ambon, several structural elements were found not to meet the applicable standards. Therefore, the objective of this study is to design and redesign the dimensions and reinforcement system of the superstructure of the Integrated Educational Building of IAIN Ambon in accordance with the standards. The analysis was conducted using the Limit Strength Method in combination with SAP2000 v.25 to evaluate the safety and serviceability of the structure. The results of the study show that the dimensions of beams and columns meet the requirements of SNI 2847:2019, with dimensions of Beam B1: 750×350 mm, Beam B2: 650×350 mm, and Beam B3: 500×300 mm. Meanwhile, the slab with a thickness of 130 mm was deemed inadequate and replaced with a thickness of 200 mm. Based on the analysis results, the designed reinforcement system satisfies both strength and geometric requirements, ensuring safety and compliance with SNI 2847:2019. Keywords: Superstructure, Limit Strength Method, SAP2000, Safety, Design.

Abstract

Concrete is a major construction material whose quality and strength are highly influenced by aggregate characteristics. This study utilized sand and coral from Motoni Beach, Ouw Village, East Saparua District, Central Maluku, to evaluate their feasibility as constituents of normal concrete. The objective was to design a concrete mixture with a target strength of 20 MPa and to analyze the resulting compressive strength. The research method was experimental in a laboratory, including aggregate characterization tests (moisture content, silt content, specific gravity, absorption, and Los Angeles abrasion), mix design calculation, preparation of cylindrical specimens (Ø15×30 cm), curing, and compressive strength tests at the ages of 7, 14, and 21 days. The results showed that Motoni sand met SNI requirements, while coral aggregate exhibited high absorption (7.30%), making it unsuitable as coarse aggregate for structural concrete. The maximum compressive strength was obtained at 14 days, reaching 21.69 MPa, but decreased to 17.17 MPa at 21 days, equivalent to 18.07 MPa at 28 days (conversion based on PBI 1971). This value did not meet the planned strength of 20 MPa. In conclusion, Motoni Beach sand is suitable as fine aggregate, whereas coral aggregate is only applicable for non-structural purposes.Keywords: Concrete, Beach Sand, Coral, Compressive Strength
