In this paper, we propose an operator model to detect and identify causes of failure in an emergency, based on which an alarm system in a process can be evaluated and improved. The operator model is a human processor model that includes a perceptual processor, short-term and long-term memories, a cognitive processor, and a motor processor. Knowledge bases for variable information, failure-sympt...

This paper presents a comparative seismic performance assessment of superelastic-friction base isolator (S-FBI) systems in improving the response of bridges under near-field earthquakes. The S-FBI system consists of a steel-Teflon sliding bearing and a superelastic shape memory alloy (SMA) device. The other isolation systems considered here are lead rubber bearing (LRB), friction pendulum syste...

Peningkatan perioda alami struktur menggunakan base isolation system dapat mereduksi koefisien respon seismik, yang juga akan mempengaruhi hasil desain dari suatu struktur. Penelitian ini bertujuan untuk mengetahui persentase penurunan berdasarkan parameter dinamik pada dengan sistem fixed di area Kota Padang bangunan gedung bertingkat sedang. Metode digunakan penelitian adalah analisis spektru...
