In seismically retrofitted reinforced concrete (RC) structures, new members are connected to existing using interfaces with roughened surfaces and post-installed dowel bars. During an earthquake, the subjected cyclic shear normal stresses. Therefore, structural design of is essential. a previous study, loads were applied interface specimens. Moreover, strength estimation method was proposed; ho...

In recent years, civil wars and terror activities have caused blast-loading effects on reinforced concrete buildings, resulting in catastrophic human material damage. When a building is exposed to blast load, very high air pressure affects the within short duration. To decide reconstruction or retrofit of loading, behavior under loading should be investigated. this paper case study RC during Li...

Abstract The development of fragility functions that express the probability collapse a building as function some ground motion intensity measure is an effective tool to assess seismic vulnerability structures. However, number factors ranging from selection modeling decisions can influence quantification probability. A methodical investigation was carried out examine effects component and in es...
