Special Issue Information

Dear Colleagues

Engineering structures are exposed to multiple natural hazards during their service periods, and strong winds and earthquakes are the two most destructive disasters for structural design. In traditional structural dynamic analysis and design schemes, the effect of a single hazard (i.e., wind or seismic load) is usually taken into account. For critical modern building and lifeline structures, however, the effects of both these two hazards should be scientifically considered to ensure structural safety and minimize human casualties and economic losses. Thus, multi-hazard structural analysis and design are now a hot research topic in civil engineering.

This Special Issue of the journal Applied Sciences, “Multi-hazard Analysis of Structures under Wind and Seismic Loads”, aims to attract new contributions covering a wide range of investigations in structural analysis and design under strong wind and earthquake loads.

Our topics of interest include but are not limited to:

  • Multi-hazards on building and lifeline structures;
  • Hazard analysis of earthquakes and strong winds;
  • Stochastic simulation of Multi-hazard loads;
  • Multi-hazard fragility analysis approach;
  • Structural performance assessment considering multi-hazards;
  • Experimental technologies for multi-hazards;
  • Multi-hazard structural design method;
  • Structural vibration control under multi-hazards;
  • Structural resilience under multi-hazards of earthquake and wind.

Cross-river bridges located in seismically active areas are exposed to two major natural hazards, namely earthquakes and flooding. As the scour depth increases, more parts of the bridge substructure will inevitably be exposed to unfavorable conditions such as chloride ion (Cl−) corrosion. To investigate the seismic performance of highway bridges under the action of scour and Cl− corrosion, a spatial finite element dynamic model of a continuous rigid bridge was established and a Cl−-accelerated electrochemical corrosion test and quasi-static test were carried out. The results showed that a reasonable scour depth and the combination sub-factors under the joint probability density of scour action and seismic action can be obtained to establish the combined expression of the action effect. Cl− corrosion can cause a reduction in displacement ductility, load-bearing, and energy dissipation capacity, and increase inequivalent viscous damping coefficient of the columns. Seismic damage of the columns grows linearly to twice the ultimate displacement under Cl− corrosion, which becomes more significant with the increase of the reinforcement ratio. Full article

In deepwater-drilling engineering, it is necessary to disconnect the bottom equipment of the lower marine-riser package from the blowout preventer when encountering multi-hazard environmental factors. In order to reduce the impact of recoil on the drilling platform after the sudden disconnection of the riser, in this paper, an optimal guaranteed cost H∞ recoil control problem is considered for the drilling riser. First, a three-element mass-damper-spring deepwater-drilling riser model subject to fluid discharge and heave motion of offshore platform is given. Then, an optimal guaranteed cost H∞ controller (OGCHC) is designed to suppress the recoil response of the drilling riser, and the sufficient conditions for the asymptotic stability of the closed-loop system are derived. Third, it is found through simulation results that the designed OGCHC can reduce the recoil response effectively. In order to further analyze the advantages of the OGCHC, the performance indices of the riser without active-recoil control and with optimal control (OC) and OGCHC are compared. It is shown that the average response amplitudes of three mass blocks of the riser are almost the same, while the control cost by the OGCHC is less than that by the OC. Further, under the designed recoil control, no riser compression occurs, thereby ensuring the safety of the riser system. Full article
