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

Jembatan Wai Dua merupakan salah satu jembatan yang dilakukan proyek penggantian jembatan dari struktur baja ke beton dengan tujuan untuk menambah lebar jalur lalu lintas. Dalam pembangunan suatu jembatan perlu adanya komposisi pembebanan struktur yang harus diperhitungkan agar jembatan dapat memikul beban-beban dan memiliki kestabilan struktur, sehingga dapat berdiri kokoh dan menjamin keselamatan serta kenyamanan bagi pengguna jembatan, khususnya pada bangunan atas jembatan. Bangunan atas jembatan sangat berperan penting pada konstruksi jembatan karena akan memikul beban-beban kendaraan secara langsung. Penelitian ini dilakukan dengan tujuan untuk menghitung besar beban yang bekerja serta dimensi dan penulangan struktur pada bangunan atas dari Jembatan Wai Dua Kota Ambon sesuai dengan SNI 1725-2016.

Abstract

A building structure is an assembly and arrangement of various elements designed in such a way that it can withstand external and self-loads without experiencing deformation beyond allowable limits. The construction of the female dormitory building at Campus II of SMKKN Manokwari has not yet been carried out according to the plan; therefore, a structural analysis is necessary to determine the magnitude of the internal forces acting and the reinforcement system. The method used is the limit strength method with the assistance of SAP2000 v.22 software. Based on the analysis results, the forces acting on the cross-section are an average support moment of 56.33 kN·m, an average field moment of 34.28 kN·m, an average shear force of 72.81 kN, and an axial force on the column of 250.08 kN. The reinforcement calculations resulted in reinforcement for the column, beam, and slab cross-sections using D16 bars, with shear reinforcement using Ø10 bars, thus classifying the cross-section as under-reinforced.  Keywords : Internal forces, Structure, Ultimate strength

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.
