The structural section of power-boiler specifications should include lateral-force design criteria to minimize the possibility for critical damage and resulting financial loss during a furnace explosion. Boilers designed for 20% g have survived violent explosions with moderate structural damage. In areas of low seismicity, reasonable protection can be attained by specifications requiring minimum lateral design forces of 10% g and redundant bracing systems with strong and ductile connections that will bend and not rupture under out-of-plane loading.
