Abstract
In recent years, several catastrophic tsunami events have captured the attention of researchers, leading to studies on the structural behaviour of buildings subjected to tsunami loads to develop efficient and practical prevention systems. International building codes and design standards have reacted by providing innovative approaches to design tsunami-resistant structures; however, analysis approaches that consider potential earthquake damage prior to the loading imposed by the tsunami are lacking. This paper aims to assess the global structural behaviour of reinforced concrete buildings subjected to earthquake damage and tsunami loading considering both in-plane and out-of-plane behaviour of infill walls on the global structural response of RC buildings. A structural analysis framework is proposed to assess the capacity of prototype buildings under tsunami loading following previous seismic-induced structural damage that is classified based on specific damage states. The procedure is based on nonlinear static pushover analysis. Analyses are performed on two different building models representing new construction and an old existing structure. This study focuses on critical aspects regarding the structural modelling and analysis. Specifically, recommendations are provided on modelling the behaviour of infill walls related to in-plane and out-of-plane local mechanisms due to its influence on the global structural behaviour. The new building provides an enhanced response over the existing building due to a more efficient design approach. Furthermore, tsunami analysis is dependent mainly on the strength capacity of the elements directly inundated, while seismic analysis involves the entire structure. The modelling of the infill walls in the structural models increases the stiffness and represents a critical element for the loading of the structure. Structural collapse during the analysis is mainly controlled by shear failure in the columns at the ground floor level.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
