Hail is one of the most serious disastrous weather phenomena， and the loss caused by hail is increasing year by year. How to reduce the hail-induced loss has become a practical problem that must be faced in the engineering field. However， the research on the hail impact resistance of structures is very limited at present. Therefore， it is of great significance to systematically investigate the theory and practice of structural hail impact disaster reduction and prevention. In this study， the mechanical properties of the hail are first summarized. Then， the experimental and numerical research status of hail resistance of engineering structures is introduced in detail. Finally， the research on the coupling effect of hail， strong wind and heavy rain and its mechanism are prospected. This study is supposed to provide the basic data and new perspectives for the research on hail resistance of structures.
