Abstract As a natural hazard, flood can cause a significant damage to buildings. Buildings are one of the important components of an economy which are providing the necessary space for human activities. In this regard, any considerable changes to their serviceability affect living condition of people locally, regionally, and even globally. Thus, building damage analysis forms a crucial part of a flood risk analysis. This review paper provides an insight into flood damage analysis for a building structure and contents: past works, current state, and required improvements. The discussed buildings include residential, commercial, and industrial types. The methods are divided into two main categories: (1) using real data and empirical models, and (2) using what-if analysis and analytical models. Differences in damage analysis of a building structure and its contents are explained in a separate section. Flood factors influencing the damage to a building structure and its contents are presented. How a method considers some of those flood factors is described. Limitations and shortcomings of each method alongside their advantages and strength are discussed. Lack of reliable data for both model construction and validation is one of the main issues with the methods in both categories. Inability to convey the uncertainty is the other main issue identified in the literature.

1 Introduction Flood is one of the natural hazards threatening civil systems including buildings. Quantifying the consequences of this hazard, such as direct damage to buildings, has been under study for years. Quantifications are conducted for different purposes at different levels. One of these quantifications relates to assessing direct damage to buildings which is conducted before and after a flood event. Before a flood event, to mention a few purposes, building damage is quantified to analyze benefit-cost ratio of potential mitigation measures, * Morteza T. Marvi [email protected] 1

to assign insurance premiums on a property, and to plan for emergency response ahead of time. After a flood event, the quantification is conducted to evaluate insurance claims filed to receive indemnities, to develop/revise predictive models for future events, and as a part of reconnaissance surveys to deploy recourses for emergency response. Thus, quantification of direct damage to buildings forms a crucial part of flood risk assessment from different perspectives of various stakeholders involved in this natural disaster. Flood is referred to a situation when a part of a land, which is usual
