Eight papers are focused on shock and blast in structures, and the topics covered are related with the response of building structural elements, as well as the effects in special infrastructures. Eleven papers were submitted related to pure dynamic and vibration modelling strategies. Since the last century, many developments have been made in understanding the seismic demand on structures due to earthquake-induced ground motions and structure response under dynamically varying loads. However, observations from the recent past earthquakes have demonstrated that structures designed to modern codes of practice and guidelines have not performed up to the expectations in reducing losses due to earthquakes. Furthermore, the recent earthquakes have demonstrated that the vulnerability of deficient; that is, noncomplaint, structures is higher than the previously known. All these are pointing to the growing interest in tools for modelling of structures under earthquake loading, to accurately account for the possible damage mechanisms and their implication on the structure response under earthquakes of
