State of the art of seismic risk and loss assessment in structures

Abstract

Earthquakes are known as one of the disasters that have fatal consequences for human safety. However, inevitably, the earthquake itself is not the leading cause of the losses suffered by humans, both material and soul. The most powerful thing in human safety is infrastructure such as buildings, bridges, and houses. Therefore, an in-depth analysis of the risk factors that the infrastructure will experience in a natural disaster is needed. There is a variable seismic hazard in the Southeast Asia region, ranging from high seismic hazard allied with the underneath of the Indonesian and Philippine archipelagos to moderate and low seismic tremors associated with a sizeable stable region on the Sunda Shelf. This paper describes the history of seismic risk and loss assessment of infrastructures. The method used is by doing literature reviews of the most recent research relating to seismic risk and assessment around the world. More than fifteen research results are studied and discussed to get a deep knowledge about seismic risk and the assessment of loss due to seismic disaster.

Studi Perilaku Balok Kastela Dengan Variasi Bentang Dan Jarak Antar Lubang Segidelapan

“…Salah satu kelebihan dari sifat baja adalah memiliki kuat tarik yang tinggi (Oentoeng Oentoeng, 2000). Konstruksi baja juga aman terhadap gempa karena sifat daktilitasnya yang tinggi (Aryanti & Masrilayanti, 2021). Dengan berkembangnya teknologi ditemukan balok kastela yang membuat penggunaan profil baja lebih bervariasi.…”

“…Earthquake disasters can claim many lives. History records that the most powerful earthquake in the last 50 years occurred in Bio-Bio Chile in 1960 with an earthquake magnitude of 9.5 Magnitude called the Valvidia earthquake, while the most powerful earthquake in 50 years in Indonesia was recorded as occurring in Aceh in 2004 which resulted in a tsunami with an earthquake magnitude of 9.1 magnitude [5].…”

Comparison of building structure performance with masonry and without masonry

“…In the Sumatra area the plates meet in a subduction zone, where the boundaries of the Indian plate are forced beneath the Australian plate. The plates are sliding northeastward at about 7 cm per year and dipping under the Sunda plate, which encompasses Sumatra and Singapore [2,3]. The city is one of the disaster-prone areas in Indonesia due to its territory lies within one of the world's most active fault lines namely the "Ring of Fire" [1].…”
