Advances in the study of simultaneous occurrence of strong wind and earthquake and their effects on structures

Abstract

<p indent="0mm">With the increasing demand for sustainable development of engineering structures, the study of engineering structures under the joint action of multi-hazards is receiving more and more attention from scholars and engineers. Are the simultaneous occurrence of strong wind and earthquake, as two major hazard loads, still uncertain as a coincidental event? To clarify the possibility of simultaneous occurrence of two hazards, this paper summarizes the current research status that strong wind and earthquake can occur simultaneously from two aspects, respectively, strong wind triggers earthquake and earthquake causes strong wind, collects data on the simultaneous occurrence of strong wind and earthquake in some areas from various factors, provides data support for the coupling phenomenon of simultaneous occurrence of strong wind and earthquake, and reviews the current research progress of engineering structures under the simultaneous action of strong wind and earthquake. It reviews the progress of related research on engineering structures under the simultaneous effects of strong wind and earthquake. The results show that: (1) Strong wind can trigger microseismic, slow earthquake, and normal earthquake by affecting waves and geological structures, and earthquakes can trigger strong wind by causing changes in atmospheric temperature and electromagnetic waves, and there is a coupling phenomenon between strong wind and earthquake. (2) The probability of simultaneous occurrence of strong wind and earthquake varies greatly in different regions, and the wind speed surface fitting can better meet the temporal and spatial relationships for collecting data on the simultaneous occurrence of strong wind and earthquake. (3) Engineering structures under the simultaneous effects of strong wind and earthquake are more prone to damage and destruction, and structural design standards should be adjusted or energy-consuming damping devices should be installed to improve their performance. Therefore, it is still necessary to improve the data related to the simultaneous occurrence of strong wind and earthquake and their mechanism of action. The comprehensive consideration of the effects of strong wind and earthquake on engineering structures is an important research direction in this field in the future.
