Tsunami Loading Analysis and Engineering Prevention and Control

Abstract

Tsunami is one of the serious natural disasters in coastal areas. Tsunami waves produce huge horizontal thrust on costal buildings, resulting in a large number of houses collapsed instantaneously, causing serious casualties and economic losses. Based on a reinforced concrete frame structure under different conditions of tsunami effect analysis, this paper clarified the calculation method of tsunami loading and proposed two kinds of the most disadvantageous combination effects of the tsunami loading, namely the combination effect of the advancing water front of a tsunami and the combination effect of the tsunami inundation. It is indicated that the right structure type and the multi-story or highrise buildings should be chosen in the tsunami damage prevention and control measures, and the ability of the key loadbearing members to resist tsunami impact at the bottom of the structure should be strengthened.
