This paper presents a study on the construction method of modular pier system using CFTs. Modular Pier System consist of various prefabricated modules and is constructed by assembling components. Research scop include development of standard modules for adjustable to various height, connection between modules, and test bed construction. For the evaluation of this systems’s performance, Many numerical and experimental studies were conducted. In this study, we develop rapid construction system for site application of modular pier.

This paper presents a study of the numerical analysis of bracing connection in modular pier system using Concrete Filled Tube members. To evaluate the structural capacity of bracing connection, which have various shapes, numerical analysis is performed. For the optimal shape of bracing connection, the shape and size of gusset plate are evaluated by using analysis results.

Building information modeling (BIM) is appropriate for the design of modular structures due to their parametric modeling technologies. This paper proposed the parametric models of modular bridge piers with multiple concrete filled steel tubes. Knowledge obtained from research works including design and fabrication was embedded in the 3D information models.
