Bending behavior of splice connection for corner-supported steel modular buildings

Splice connection consisting of slip-critical high strength bolt and side plate is a promising type for future modular construction. However, recognitions on basic performance this are still limited. To fill gap, paper conducted comprehensive research bending behavior simple splice proposed by the authors corner-supported steel building. The was analyzed in details combined experiments numerical simulations. It found that can achieve favorable ductile bending. Bilinear profile with two stages clearly observed relationship between moment rotation. These have different stiffness but applied load keep increasing second stage excessive deformation specimen. Such phenomenon reveals adequate reserve resistance under large scenario. Based method farthest point, transition point defined determined This represents an important change behavior, which valuable practical design. Numerical simulations also introduced to supplement tests. analyses stress states components variation pre-tension force properly explains anisotropy at loading directions. A parametric study further conducted. Results indicate possesses satisfactory tolerance loss
