In this presentation, recent developments on the analysis and design of concrete hollow block walls subjected to blast loading at the UP Institute of Civil Engineering are presented. Blast phenomenon is reviewed and its idealization or implementation in codes, such as in ASCE/SEI 59-11 and the Unified Facilities Criteria, is also presented. Along with the analysis procedures making use of an equivalent single degree of freedom (SDOF) for one-way walls and Discrete Element Models, tools or programs developed by researchers were presented. These simple tools were...
