Abstract

Pelaksanaan kepala jembatan X dilakukan di tahun 2015 yang direcanakan pada tahun 2013 masih menggunakan peraturan yang terdahulu yaitu SNI 2833:2008. Sehubungan dengan dikeluarkanya peraturan baru yaitu SNI 2833:2016 maka terdapat perubahan beban gempa rencana dari peraturan lama ke baru sehingga perlu dilakukan evaluasi terhadap kapasitas kepala jembatan terhadap beban gempa rencana sesuai SNI 2833:2016 dan dilakukan justifikasi perkuatan apabila kepala jembatan tidak layan menerima beban yang bekerja . Evaluasi kapasitas kepala jembatan dilakukan dengan cara melakukan pengecekan terhadap kapasitas dimensi, kapasitas tulangan, kapasitas daya dukung pada  pondasi dan lendutan menggunakan software SAP2000 untuk menganalisisnya. Hasil penelitian menunjukan bahwa kapasitas pada dimensi kebutuhan tulangan didalam dimensi kepala jembatan masih memadai di semua bagian, kapasitas tulangan yang terpasang disetiap bagian kepala jembatan lebih besar dari hasil analisis sehingga masih kuat menahan beban yang bekerja, kapasitas daya dukung pondasi yang lebih kecil dibandingkan dengan daya dukung izin dan lendutan yang terjadi dibawah yang diizinkan, maka kepala jembatan masih kuat menerima beban yang bekerja sehingga tidak dilakukan justifikasi perkuatan.

Abstract

In the implementation of the construction of the Main Bridge on the X Toll Road project, there was a change in the shape of the structure in the form of a slope of the P2 pile that did not match the DED by 3°. So that with the change in the shape of the structure, it is necessary to evaluate the capacity of the P2 pile and the influence on other structures must be considered. This research discusses how the capacity of the pile after experiencing a slope and how to handle it properly if the pile capacity is inadequate. Pile capacity evaluation is done by checking the dimensional capacity, reinforcement capacity, foundation bearing capacity, and deflection of the P1-P2 superstructure using the help of software SAP2000 in analyzing. The results showed that the pile capacity at P2 was inadequate, indicated by the lack of reinforcement on the piles as much as 6-D10,7 mm and column P2 as much as 9-D10,7 mm. As a result of inadequate pile capacity, the P1-P2 connection lacks top reinforcement. Therefore, structural strengthening is needed to make the P1-P2 structure more rigid by making bracing concrete with a length of 18,78 meters, a width of 33,92 meters, and a thickness of 0,8 meters with the need for longitudinal reinforcement and transverse reinforcement D32-250. After the structural strengthening is done, the required area of reinforcement for columns P2, piles P2, and connections P1-P2 are all fulfilled with those already installed in the side.

Abstract

Beton porous non pasir dengan slag baja merupakan salah satu beton yang ramah lingkungan. Beton ini dapat menjadi alternatif untuk mengatasi permasalahan kerusakan jalan akibat genangan air, terutama pada trotoar, jalan taman, atau jalan lingkungan dalam skala terbatas. Slag baja dapat menggantikan agregat kasar karena memiliki kuat tekan yang mendekati agregat batu pecah. Penelitian ini bertujuan untuk menganalisis pengaruh substitusi steel slag terhadap kuat tekan beton porous non pasir. Penelitian eksperimental ini menggunakan dua variasi faktor air-semen (w/c 0,25 dan w/c 0,3) dengan dua variasi agregat batu pecah dan steel slag dengan diameter 10 mm-20 mm. Uji tekan pada benda uji dilakukan pada umur 14 hari, 21 hari, dan 28 hari. Penelitian ini mengacu pada ACI 522R 10. Penelitian ini menunjukkan bahwa kuat tekan beton porous non pasir menggunakan steel slag sebagai agregat kasar memiliki kuat tekan yang lebih rendah dibandingkan beton tidak halus porous menggunakan batu pecah.

Abstract

Makalah ini memaparkan hasil penelitian kinerja struktur jembatan tipe voided slab. Penelitian ini dilakukan oleh adanya masalah terkelupasnya lapisan permukaan dan terbentuknya alur memanjang di permukaan lantai jembatan tipe voided slab. Tujuannya untuk mengevaluasi kinerja standar jembatan tipe pre-tensioned precast concrete voided slab bentang 16 m, dengan tinjauan beban sesuai SNI 1725:2016 dan beban aktual. Dalam evaluasi ini dilakukan uji lendutan terhadap struktur jembatan voided slab ,untuk mengetahui lendutan yang terjadi pada struktur yang elemennya menyatu dan yang terpisah. Pendekatan teoritis dilakukan untuk mengetahui kinerja struktur terhadap beban aktual dan beban standar sesuai dengan SNI.1725:2016. Hasil uji menunjukkan bahwa jembatan voided slab yang lapisan permukaan lantainya terbentuk alur memanjang, terindikasi antar elemennya tidak menyatu, perbedaan lendutan antar elemen sebesar 8,9 mm, dan terdiskripsi tidak layak. Bagian lapisan permukaan lantai jembatan yang tidak terbentuk alur memanjang, terindikasi antar elemen masih menyatu, perbedaan lendutannya sebesar 0,76 mm, dan terdiskripsi layak. Hasil uji di lapangan juga menunjukkan bahwa bagian elemen voided slab yang tidak menyatu, terindikasi tidak layan menerima beban aktual, dengan lendutan sebesar 13,34 mm, lebih besar dari lendutan izin sebesar 7 mm, dan bagian elemen voided slab yang menyatu, terindikasi layan menerima beban aktual, dengan lendutan sebesar 5,79 mm, lebih kecil dari lendutan izin sebesar 7 mm. Hasil analisa teoritis menunjukkan bahwa struktur voided slab yang elemennya tidak menyatu, tidak layan menerima beban standar, dan struktur yang antar elemennya menyatu, dalam kondisi layan menerima beban standar. Kesimpulan pada evaluasi ini adalah struktur voided slab dapat berkinerja baik (layak dan layan) jika antar elemennya menyatu. Agar tetap menyatu, disarankan untuk dilakukan perubahan tipe ikatan antar elemen voided slab yang dapat memberikan jaminan ikatan selama umur rencana jembatan.Kata kunci: Voided slab, menyatu, layak, layan.

Abstract

Pada proyek pembangunan Jalan Tol X, terdapat jembatan Flyover Y yang direncanakan dengan panjang 66,5 meter terbagi menjadi 2 bentang. Struktur atas jembatan direncanakan menggunakan Precast Concrete – I Girder (PCI Girder) dengan panjang 40,6 meter. Posisi Pilar 1 jembatan direncanakan berada di tengah bantaran sungai. Dengan adanya larangan pembangunan pilar ditengah bantaran sungai mengakibatkan adanya perubahan perencanaan awal bentang jembatan yaitu dari kepala jembatan A1  – pilar (P1) dan Pilar 1 (P1) – pilar 2 (P2) menjadi satu bentang dari kepala jembatan A1 – pilar 2 (P2). Perubahan juga dilakukan terhadap desain struktur atas dari rencana awal menggunakan PCI Girder dengan bentang 40,6 meter diubah menjadi Steel Tub Girder dengan bentang 66,5 meter. Jadi, perubahan pembebanan dari struktur atas akan berpengaruh pada kapasitas kepala jembatan. Untuk mengevaluasi kapasitas abutment A1, dilakukan analisa struktur menggunakan bantuan software. Hasil evaluasi kapasitas struktur abutment didapatkan bahwa tulangan yang terpasang pada bagian backwall, wall, pilecap, dan borepile  yang terpasang masih memadai. Dikarnenakan abutment A1 masih dalam kondisi layan dimana tulangan yang terpasang lebih besar dari tulangan hasil analisa, maka tidak diperlukan perkuatan.Kata kunci: Abutment; Jembatan; Perkuatan.

Abstract

Abstract Problems related to road damage are currently growing. Damages that occur are often caused by waterlogging. One of the efforts that can be done is by applying the use of porous concrete. Porous concrete can reduce water runoff and increase infiltration in the soil because it has a high porosity. As a substitute material, steel slag can be an alternative in replacing coarse aggregate. Steel slag is an abundant waste from steel production industrial companies. Currently, steel slag is widely used in high-strength concrete mixes. This study of porous concrete generally refers to ACI 522R 10. The purpose of this study was to analyze the effect of steel slag substitution on the tensile strength and permeability of porous concrete. This experimental study used two variations of the w/c (0.25 and 0.30) with two variations of crushed stone aggregate and steel slag with a diameter of 10 mm-20 mm. The tensile strength and permeability specimen of porous concrete is in the form of a concrete cylinder (15 cm diameter, 30 cm height) with 3 samples of each variation. The tests were carried out at the age of 28 days. Based on the experimental results on porous concrete with steel slag or crushed stone, the value of the tensile strength of concrete with w/c 0.30 is higher than w/c 0.25. Meanwhile, the permeability value of porous concrete in both the mixed variant of steel slag and crushed stone with w/c 0.25 is higher than w/c 0.30. So that the relationship of the tensile strength of concrete is inversely proportional to the value of the permeability of the concrete in the conditions of the two w/c (0.25 and 0.30). Keywords : porous concrete, tensile strength, permeability

Abstract

AbstractKeramasan Bridge 2 is a bridge with an age of more than 30 years, so it is necessary to review its feasibility and serviceability. Based on the loading test results, it is stated that the deflection on the girder exceeds the permissible deflection. Based on this, it is necessary to strengthen the upper structure. The strengthening of the upper structure is carried out by installing a diaphragm between the girders. The diaphragm is an angled steel profile of 100 mm x 100 mm with a thickness of 10 mm.To determine the number and position of diaphragms, two alternatives were analyzed. The first alternative is to add three diaphragms at 1/4, 1/2, and 3/4 span. In the first alternative, the deflection value is 26.9754 mm. In the second alternative, the diaphragm is installed every 3 meters distance. The addition of the diaphragm produces a deflection of 27.1634 mm. The results of the analysis indicate that with the addition of a diaphragm, there is a reduction in deflection. In the first and second alternatives, a deflection that meets the permissible deflection is produced (31.375 mm). Considering the safety factor, the first alternative is used because adding three diaphragms affords the smallest deflection (26.9754 mm).Keywords: Deflections, Diaphragm, Strength, Bridge Upper Structure

Abstract

One of the bridges on the Serpong-Balaraja Toll Road section 1a project with the longest span is the Cisadane Bridge, which will employ a PCI Girder superstructure with a length of 50.8 meters. The approach road structure for the Cisadane Bridge was originally intended to employ Cermaton with a soil pile that was 6–8 m high. However, during construction, the design of the approach road changed from Cermaton to pile slab. In order to determine which structure is the most suitable for use, it is required to assess its performance. The SAP2000 program was used to check the bearing capacity of the foundation, the settlement that took place, and the structural capacity against seismic loads as part of the evaluation that was done as a result of changes in the structural design. The study results for structural design change demonstrated that the Cermaton was not superior to the pile slab since the Cermaton's decrease, which was 11.3 mm as opposed to 1.06 mm for the pile slab, was substantially greater. For an analysis of earthquake loads using SAP2000 software, it was found that Cermaton is not strong enough to withstand earthquake loads, while the pile slab is strong enough to withstand earthquake loads because the capacity of the pile slab is still adequate.

Abstract

The construction of integral bridge Overpass Cilenggang 1 on the Serpong – Balaraja Section 1A Toll Road Construction Project was built on soft soil. This evaluation aims to analyze the strength of the integral bridge substructure and justify the strengthening of the substructure if it is not strong enough to withstand the load in accordance with SNI 1725:2016. The evaluation substructure of the integral bridge capacity used SAP2000 software with the load accordance to SNI 1725:2016 for bridge loading. The result of the research show that the capacity of the integral bridge Overpass Cilenggang 1 structure is strong enough to withstand the working load because the reinforcement capacity used for the substructure is stronger than the reinforcement from the result of analysis with SAP2000 software. Based on the result of the research, it can be concluded that the reinforcement used for Overpass Cilenggang 1 substructure is strong enough to withstand the load working on structure and there is no need to justify the reinforcement for the integral bridge substructure. Keywords: Evaluation, Integral Bridge, Load, Reinforcement, Substructure.
