Retrofitting of a Multi-Span Simply Supported Bridge into a Semi-Integral Bridge by Zhen Xu, Xiaoye Luo, Khaled Sennah, Baochun Chen, Yizhou Zhuang

“…According to the response spectrum analysis, the maximum longitudinal displacement of the semi-integral bridge’s main beam is 11.6 mm, reduced by 80.1% compared to the simply supported bridge under a dead load and earthquake effects. The maximum bending moment and shear force on the pier of the semi-integral bridge are 984.7 kN·m and 312.6 kN, respectively, both below their ultimate bearing capacities. …”

Classification of Non-Seismic Tsunami Early Warning Level Using Decision Tree Algorithm by Elmo Juanara, Chi Yung Lam

“…Background: Tsunami caused by volcanic collapse are categorized as non-seismic uncommon events, unlike tsunamis caused by earthquakes, which are common events. The traditional tsunami early warning based on the seismic sensor (e.g. earthquake detectors) may not be applicable to volcanic tsunamis because they do not generate seismic waves. …”
