Evaluasi kondisi jembatan diperlukan untuk me lihat keadaan sebagai tindakan pencegahan terjadi kerusakan yang lebih besar pada struktur jembatan. Jembatan Kuranji terbagi menjadi 2 bagian yaitu lama berusia 30 tahun dan baru 9 tahun. dilakukan dengan menggunakan pengukuran mikrotremor. Pengukuran di 12 titik durasi perekaman 90 menit. Hasil mikrotremor diolah metode Horizontal to Vertical Spec...

based on the standards for design of structures, any structure should be designated for seismic loads and any combinations containing seismic loads. for spectral analysis of a structure, the site effect is taken into account by considering its effects on the design spectra. because of different lateral and vertical stiffness of the soil layers underneath the structure, the design spectra are di...

Getaran kereta api merupakan salah satu sumber mikrotremor. ini perlu dianalisis untuk mengetahui dampak terhadap lingkungan di sekitar jalur api. Pengukuran mikrotremor telah dilakukan menggunakan metode horizontal to vertical spectral ratio (HVSR) Kota Padang. Tujuan penelitian adalah karakteristik geologi setempat dan tingkat getaran mekanik akibat pada daerah padat rumah penduduk 5 titik de...

Recently, concerning failure of structures due to earthquakes, special investigations of near fault ground motions have been noticed. Hence, in this paper, characteristics of near field ground motions have been considered in horizontal and vertical directions. In this consideration, the record averages have been compared with Uniform Building Code and Eurocode8 spectra in two levels. In additio...

the destructions caused by many recent earthquakes shows that the subsurface structure directly affects the ground motions. especially in areas with possible seismic hazard expectation, expansion of cities has come up with detailed vulnerability analysis. therefore, site response investigation is a key step in every microzonation study. one of the best approaches for understanding the geologica...
