기존건축물의 수직증축을 위한 방안 비교

With the growing interest in eco-friendly construction and greening all over the world, there has been an increasing interest in remodelling than rebuilding in order to reduce construction waste. In this study, as part of the study of green spreading for existing buildings, we examine the validity of the modular extension. Examined the structural safety in case of performing the modular extension method and existing extension method for the vertical extension of the building on the one floor of an existing three-story reinforced concrete building. In addition, member design and reinforcing design of each extension method, two methods were compared. Comparison of the two extension methods for safety and economy, the cost of the RC extension method will take at least when compared to modular expansion, the cost of reinforcing the existing members became larger.
