Steel modular buildings are growing in popularity because of its affordability, rapidity of construction, and sustainability. As the demand for modular construction methods applied to high-rise buildings increases today, strength design of modular nodes is very important in terms of safety and serviceability. This paper presented to conduct tensile, compression, and bending experiments according to the components of the modular nodes for each location and verify the performance of the modular nodes compared to the FEM analysis accordingly. This paper presents a new and innovative modular steel construction method for Design for Manufacture and Assembly (DfMA) that uses innovative connectors fabricated by a casting method using 3D-sand printed mold, and rectangular steel section (RHS) members. The paper describes the novel modular connectors, as well as the test method and findings, the development of a finite element model, and a parametric investigation. |
