Analisis riwayat waktu nonlinier akan dilakukan pada jembatan melengkung putar balik dengan radius 45 meter. Jembatan yang sangat tidak beraturan ini akan dievaluasi dengan melakukan analisis riwayat waktu nonlinier pada model jembatan yang divariasikan menjadi 3 tipe sambungan: i sambungan kaku ii sambungan sendi iii sambungan lead rubbber bearing. Sendi plastis dimodelkan pada bagian dasar dan bagian atas dari pilar dengan menggunakan sendi plastis fiber. Hasil analisis menunjukkan bahwa jembatan dengan satu perletakan memberikan tingkat kinerja yang lebih baik dibandingkan jembatan dengan dua perletakan, tetapi jembatan dengan satu perletakan lebih kritis terhadap masalah torsi.

ABSTRACT
Non linear time history analysis will be presented in irregular U turn curved bridge with radius of 45 meters. This highly horizontally curved bridge is evaluated by performing nonlinear time history analysis on the representative bridge model with 3 types of connection i rigid connection ii hinge connection iii lead rubber bearing connection. Nonlinear hinge was modelled at the base and top of the pier by using fiber hinge. The analysis results indicate that bridges with one connection give better performance level than bridge with two connections, but bridges with only one connection is more critical to the torsion issue."

"ABSTRAK
Pada perkembangan desain moderen, aspek arsitektural dari jembatan harus di ekspresikan dalam desain struktur. Rangka pada jembatan akan lebih menarik secara visual jika tidak memiliki rangka diagonal, sehingga jembatan dengan sistem balok menerus atau sitem rangka vierendeel merupakan pilihan yang tepat. Penelitian ini berfokus pada respon seismik dari struktur jembatan balok menerus dan jembatan vierendeel dengan memvariasikan kekakuan elastomeric rubber bearing, kekakuan pilar, panjang bentang jembatan, dan jenis pilar. Hasil penelitian menunjukkan bahwa penggunaan sistem rangka vierendeel lebih efisien dibandingkan sistem balok menerus.

ABSTRACT
In the development of modern design, the architectural aspects of the bridge must be expressed in the design of the structure. The frame on the bridge will be more visually appealing if it does not have any diagonal frame, so a bridge with a continuous beam system or vierendeel system is the right choice. This study focuses on the seismic response of the continuous bridge beam structure and vierendeel bridge by varying elastomeric rubber bearing stiffness, pillar rigidity, the span of the bridge, and pillar type. The results showed that the vierendeel frame was more efficient than continuous beam system. "

"Lokasi jembatan pada daerah rawan gempa dan penurunan mutu beton secara signifikan menyebabkan perlunya studi lebih mendetail mengenai perilaku inelastik pier jembatan tersebut. Perilaku inelastik jembatan dapat diidentifikasi melalui analisa nonlinear time history pada sendi plastis yang terjadi pada kolom pier. Untuk mendapatkan perbandingan perilaku sendi plastis, maka pier dimodelkan menjadi dua, yaitu model desain (mutu rencana) dan model eksisting (mutu rendah). Kondisi akhir penampang pasca eksitasi gempa dapat diketahui dengan menggunakan elemen fiber pada program MIDAS CIVIL. Hasil simulasi yang dilakukan menunjukkan bahwa hampir semua penampang model eksisting mengalami crushing beton, sementara penampang model desain hanya mengalami cracking. Selain itu, juga terjadi perubahan tipe kegagalan struktur dari kegagalan daktail pada model desain menjadi kegagalan getas pada model eksisting.

Bridge located at seismic zone and the concrete strength deterioration lead to a more detailed investigation of the inelastic behaviour of the bridge. The inelastic behaviour can be identified by nonlinear time history analysis on the plastic hinge, which occur at the column. For results comparation, two models are used for the pier which are deign model (initial design compressive strength) and existing model (low compressive strength). Final condition of the column section after lateral excitation can be obtained by assigning fiber element on MIDAS CIVIL. Simulation results show that concrete crushing occur at the existing model section overall, while on design model section only concrete cracking exist. Furthermore, change of failure mode develops from ductile failure (design model) to brittle failure (existing model)."

"Perilaku pasca elastik struktur jembatan akibat beban siklik gempa dapat ditunjukkan dengan melakukan analisa riwayat waktu nonlinear. Desain struktur berbasis kinerja (performance based design) diawali dengan pembentukan sendi plastis pada elemen nonlinear jembatan yang tergambar pada kurva momenrotasinya. Definisi potensi sendi plastis dinyatakan dengan penentuan panjang sendi plastis (lp) dan diskritisasi fiber section pada elemen nonlinear struktur (pilar jembatan).
Penelitian ini bertujuan untuk melakukan studi parametrik panjang sendi plastis, bentuk penampang pilar, serta pemodelan pondasi terhadap kinerja struktur yang dihasilkan. Disamping itu juga dilakukan tinjauan sensitifitas spektrum gempa terhadap pembentukan sendi plastis. Penelitian ini diawali dengan melakukan pemodelan struktur jembatan, dimana pilar jembatan didesain ulang agar mengalami pelelehan pada saat gempa berlangsung.
Hasil penelitian menunjukkan bahwa panjang sendi plastis yang ditempatkan pada pilar berbanding lurus dengan maksimum rotasi yang dihasilkan. Bentuk penampang pilar bulat terbukti memiliki kinerja yang lebih baik dibandingkan penampang persegi. Selain itu, pemodelan pondasi dalam desain struktur sebaiknya juga dilakukan untuk mendapatkan desain yang lebih konservatif. Dalam studi sensitifitas spektrum gempa, ditunjukkan bahwa respons struktur akan teramplifikasi pada saat frekuensi natural struktur berdekatan dengan muatan frekuensi dominan spektrum gempa.

Structural post-elastic behavior due to earthquake cyclic loading can be shown by examining a nonlinear time history analysis. Structural design using the approach of performance based design is started with the forming of plastic hinges on the bridge nonlinear elements that is captured on its moment-rotation curves. The definition of potential plastic hinges is defined by the assignment of plastic hinge length (lp) and the discretization of fiber section on structure?s nonlinear elements (bridge piers).
The purpose of this research is to do a parametric study of plastic hinge length, piers cross section shape, and the foundation modeling to the obtained structural performance level. Besides that, this research will also review the sensitivity of earthquake spectrum to the forming of plastic hinges. This research is started with bridge structural modeling, where the piers will be redesigned so that their yielding limit exceeded when the earthquake happened.
The result of this research shows that the assignment of plastic hinge length is proportional to the obtained maximum rotation. Circular sections have a better performance compared to rectangular sections. Besides that, foundation modeling in structural design should be observed to get a more conservative design. In the sensitivity study of earthquake spectrum, this research shows that structural responses will be amplified when the frequency content of the motion and the natural frequencies of the structure are close to each other.

"Manuver u-turn oleh kendaraan berat memiliki waktu tempuh serta dampak terhadap lalu lintas berbeda dengan manuver u-turn oleh kendaraan ringan disebabkan perbedaan karakteristik antara kedua tipe kendaraan tersebut, sehingga analisis mengenai dampak manuver u-turn oleh kendaraan berat secara spesifik diperlukan. Teori shock wave dipilih sebagai pendekatan analisis pada penelitian ini karena dianggap lebih cocok digunakan untuk menganalisis dampak manuver u-turn pada jalan dengan lalu lintas kendaraan berat yang tinggi dibandingkan dengan pendekatan lain seperti tundaan dan tingkat layanan. Tujuan penelitian ini adalah menganalisis panjang antrian akibat manuver u-turn kendaraan berat pada jalur asal serta pada jalur tujuan kendaraan berat yang melakukan u-turn untuk berbagai kondisi komposisi kendaraan berat dan rasio kendaraan berat yang melakukan u-turn terhadap seluruh kendaraan berat yang melintas pada jalur asal kendaraan berat yang melakukan u-turn.
Dalam metodologi penelitian ini, data panjang antrian diperoleh dari hasil simulasi lalu lintas mikroskopik menggunakan VISSIM, di mana model lalu lintas mikroskopik yang digunakan pada simulasi dikalibrasi serta divalidasi menggunakan data lapangan yang didapatkan dari survei di salah satu bukaan median Jalan Marunda Bidara, Jakarta Utara. Berdasarkan tujuan penelitian, variabel bebas, terikat, dan terkontrol yang digunakan yaitu komposisi kendaraan berat (%KB), panjang antrian, serta arus kendaraan dari hulu yang melintas dalam skr dan rasio jumlah kendaraan berat yang melakukan manuver u-turn terhadap jumlah seluruh kendaraan berat yang melintas pada jalur asal kendaraan berat yang melakukan u-turn (%KB u-turn) secara berturut-turut.
Berdasarkan hasil analisis, dapat disimpulkan bahwa di bukaan median yang lalu lintas u-turn kendaraannya didominasi oleh kendaraan berat, pada jalur asal kendaraan berat yang melakukan u-turn, apabila komposisi arus kendaraan berat dan rasio jumlah kendaraan berat yang melakukan u-turn terhadap jumlah seluruh kendaraan berat yang melintas pada jalur tersebut diketahui, maka panjang antrian dapat dirumuskan dengan model linier. Sedangkan pada jalur tujuan kendaraan berat yang melakukan u-turn, panjang antrian tidak dapat dirumuskan berdasarkan komposisi arus kendaraan berat dan rasio jumlah kendaraan berat yang melakukan u-turn terhadap jumlah seluruh kendaraan berat yang melintas pada jalur asal kendaraan yang melakukan u-turn.

U-turn manuvers by heavy vehicles have travel times and effects towards traffic that differ from that of light vehicles due to the differences in the characterstics of the two vehicle types, therefore an analysis on the effects of u-turn manuvers by heavy vehicles specifically is deemed necessary. Shock wave theory has been chosen as the approach for analysis in this study due to it being considered more suitable for analyzing the impact of u-turn maneuvers on roads with high heavy vehicle traffic compared to other approaches such as delay and level of service. The purpose of this study is to analyze the lengths of queues caused by heavy vehicle u-turn manuvers on the u-turning heavy vehicles’ initial and final carriageways for various heavy vehicle compositions and ratios of u-turing heavy vehicles to total heavy vehicles passing through the initial carraigeway.
In the methodology of this study, queue length data is obtained from the results of microscopic traffic simulation using VISSIM, where the microscopic traffic model used for simulations is calibrated and validated using field data from one of the median openings on Jalan Marunda Bidara, North Jakarta. Based on the purpose of the study, the free, bound, and control variables used are heavy vehicle composition (%KB), queue length, and upstream traffic volume in pcu along with the ratio of u-turning heavy vehicles to total heavy vehicles passing through the u-turning heavy vehicles’ initial carriageway (%KB u-turn), respectively.
Based on the analysis, it can be concluded that, on median openings where the u-turn traffic is dominated by heavy vehicles, on the initial carriageway of u-turning heavy vehicles, if the heavy vehicle composition and the ratio of u-turning heavy vehicles to total heavy vehicles passing through the carriageway are known, the queue length can be formulated with a linear model. Whereas on the final carriageway of u-turning heavy vehicles, the queue length cannot be formulated based on heavy vehicle composition and ratio of u-turning heavy vehicles to total heavy vehicles passing through the carriageway
