Assessment methods for blast loads and time dependent impact response analysis of building subjected to blast load have been showed. First, assessment methods for blast loads proposed by previous researchers were compared. The result indicate that each assessment method for blast loads was in consistency as magnitude of blast load was below of level weight concrete structure collapse. Next, time dependent impact responses of a high rise reinforced concrete building with 20 stories was executed subjected to blast load. It was found that response of upper layer of the building subjected to blast load with L3 was almost same as the case when the seismic wave of level 2 was applied. But the response of lower layer of the building was 1.3 to 5.1 times that due to the level 2 seismic wave.
