In this study, grouted couplers were used to connect steel bars as an alternative approach the conventional bar lapping method. The aim is avoid congestion problems and reduce required quantity of in order achieve development length practice. Two categories couplers, i.e., short-threaded grout coupler long coupler, nine groups well one group deformed bars, tested under uniaxial tension. total, ...

In steel modular buildings, both inter- and intra-module connections can attract bending moment under the action of lateral loads. The is distributed in accordance with relative stiffness ratios among structural components hence should have sufficient flexural resistance to connecting members be classified as a rigid connection. Typically, (beam-column joints within module) are designed full-st...
