For boiling water reactors and small reactors, an effective way to reduce containment pressure is to discharge gas from the containment into the suppression pool. Based on the above background, a series of experiments were conducted to investigate th

Abstract The tunnels might be suffered from damage and destruction under the dynamic loads generated by trains moving on the upper railways, which can in turn threaten the safety of the railways. Understanding the dynamic response of tunnel under the

Two types of city-oriented noise barriers, i.e., fully-enclosed noise barrier and bilateral inverted l-shaped semi-enclosed noise barrier, have been gradually adopted in city centres along high-speed railways to reduce noise pollution. The aerodynami

A literature review on the spectral content of seismic ground motion indicates that a clear predominant frequency in earthquakes is very difficult to define. Here, it is considered that this has been so because the usual seismic record or response qu
