Studi Alternatif Bentuk Rangka Jembatan Canai Dingin Untuk Pejalan Kaki Bentang Kecil Terhadap Rasio Berat dan Lendutan
Get PDFPada daerah terpencil banyak ditemui jembatan sederhana (non-engineered bridge) yang mengalami kerusakan. Salah satu alternatif untuk menyelesaikan masalah jembatan pada daerah terpencil untuk pejalan kaki adalah menggunakan jembatan rangka dengan material canai dingin. Jembatan sistem rangka adalah bentuk yang ideal untuk material canai dingin yang rawan mengalami tekuk. Beberapa bentuk jembatan rangka yang banyak diaplikasikan adalah tipe Warren truss, Pratt truss, Howe truss dan K-truss.Penelitian ini membahas pengaruh bentuk rangka terhadap rasio berat dan lendutan yang terjadi akibat beban pejalan kaki pada bentang pendek (L = 4m). Dalam pengembangan bentuk rangka ini mengacu pada bentuk rangka yang banyak diaplikasikan, menggunakan pembebanan sesuai SNI 1725-2016 dan analisa penampang canai dingin berdasarkan SNI 7971-2013. Usulan bentuk rangka yang dihasilkan juga akan dilakukan pengujian beban di laboratorium. Hasil dari penelitian ini diharapkan dapat diusulkan alternatif bentuk rangka baru jembatan canai dingin dengan lendutan yang paling kecil
Experimental and analytical assessment of 60 m steel truss bridge
No full textThe experimental test was conducted on a new 60 m Steel Truss Bridge at Lumajang East Java. The Purpose of the test to observe the actual condition of the bridge before use for regular traffic. The static and dynamic loading test were applied. For static loading 63% of live load was applied. Several test instruments were installed to record all data during testing. Seven stages of loading were performed during static loading test. The structural analysis also performed as comparison with the experimental result. The experimental test and analytical study showed that the Steel Truss Bridge provides good performance refers to current Indonesian code

Seismic Confinement Design for Rectangular Columns With Considering Shear Effect
Get PDFThis research discusses the role of transverse reinforcement as seismic reinforced concrete columns confinement. The latest confinement design addressed for columns remains standing under certain level of axial compression and displacement demands. However, this purpose did not consider shear effect. An approach formulation to determine the amount of confinement for reinforcement concrete that account effect of shear is provided. This method is based on combined effects of axial and shear stress that found in coulomb failure criterion. The proposed formulation are tested in 163 column test result data base and compared with several building codes. The result showed that the formulation can reduce amount of confinement safely for most columns
