Abstract
Reinforced concrete frame structures are traditionally modelled by assuming that loads are applied after building construction is completed. However, this assumption overestimates column deflections and does not represent the realistic behavior. At the present time, it is possible to model reinforced concrete structures realistically due to the development of computing technology. In this study, building construction sequence and its effects are considered and loads are applied as each floor is constructed story by story. Moreover, time-dependent effects such as creep and shrinkage are considered for evaluating the whole structural behavior and analysis outcomes are compared with conventional analysis results. Furthermore, different design code approaches for creep and shrinkage are considered and their structural effects are also evaluated. In order to assess the differences in structural responses according to these approaches, 15 story reinforced concrete frame building is designed and analyzed according to design codes. Analysis results showed that the way of structural modelling and type of analysis considerably affected column deflections and behavior of members. Thus, this study reveals the importance of computational modelling and structural assumptions in building constructions.
