Experimental study of grouted sleeve connections under bending for steel modular buildings

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-strength connections, while inter-module normally pin-connected for fast-track construction. This paper proposes use grouted sleeve connection which does not require bolting or welding achieve construction buildings. An experimental programme carried investigate two types shear-keyed versus slot-hole sleeve, loading evaluate their performance terms strength, stiffness, ductility. results showed that adequate ductility resist they partial strength braced analytical model, based on EN1992-1-1, proposed predict purpose design.
