Abstract

This paper proposes a novel modular steel assembly method for manufacturing and assembly design (DfMA) using innovative connectors produced by casting with 3D printed sand molds and rectangular steel cross-section (RHS) members. The demand for modular construction methods in high-rise buildings is growing due to their economic and sustainability advantages in reducing construction time. With the increasing demand for modular construction techniques in high-rise buildings, rational structural design of modular joints is crucial for safety against progressive collapse and practicality. This paper presents the results of experiments on tension, compression, and shear of modular nodes at each location, and compare and validate the performance of modular nodes through FEM analysis. This paper describes the structural performance validation, development of finite element models, and experimental methods and results for new modular joints for parametric investigation, demonstrating the reliability of finite element analysis models.
