Karakteristik Dan Parameter Subduksi Sumber Gempa Pulau Jawa

“…Parameter dari model subduksi meliputi lokasi (koordinat longitude dan latitude), annal rate, sudut penunjaman subduksi dan b-value pada area subduksi. Parameter tersebut didapatkan dari data gempa yang pernah terjadi didaerah tersebut dengan batas kedalaman tiap-tiap area subduksi (Erlangga, 2020). Sumber gempa subduksi terdiri dari zona megathrust (interplate) yang berada pada kedalaman kurang dari 50 km dan zona benioff (intraslab) pada kedalaman lebih dari 50 km.…”

Impact of Ground Motion Selection on The Seismic Assessment of Reinforced Concrete Buildings

“…Another important consideration is selecting an analysis method among the several that are commonly used in the engineering community, such as Pushover and Nonlinear Time History Analysis (NTHA). Pushover despite their results are underestimated the expected seismic effect (Hussain and Aljassim 2021), while NTHA is considered to be more accurate, it is excluded because its output is difficult to control and is related to the GMs data used (Eelangga, Teguh, and Makrup 2020). The important part of getting reliable results from the NTHA method is to select GMs that accurately predict a future earthquake (Morris et al 2019).…”
