This paper analysed the differences of influence of explosion load and earthquake action to structure from the action characteristics of explosion load to reinforced concrete structure, analyzed and compared the differences of anti-seismic and progressive collapse resistance, the re- sults showed that collapse resistance was different from anti-seismic, the beneficial effect of continuous anti-seismic design cannot replace the eollaose resistance design.%从爆炸荷载对钢筋混凝土结构作用的特点来分析爆炸荷载对结构的影响与地震作用对结构影响的区别，对抗震与抗连续倒塌的区别进行了分析与比较，结果表明：抗倒塌不同于抗震，结构抗震设计的有益作用并不能取代抗倒塌设计。
