    Abstract


    The minimum height of mesh according to standard TCXDVN9385:2012 was not clearlydefined. The aim of this study was to propose theheight of mesh-type air - terminationaccording tothe standard TCXDVN9385: 2012 to achieve high protection. When buildingsnot higherthan 20m, a mesh width of 5m x 10m and 10m x 20m can beinstalled at a height 16cmand21cm, respectively. If the height of buildings greater than 20 m rolling - sphere method,with 4 mesh type are 5m x 5m,10m x 10m,15m x 15m and 20m x 20m atminimum height of 5cm, 10cm,15cm,and 20cm, respectively, can be used..
