Prefabrication by off-site manufacturing leads to a reduced overall construction schedule,
improved quality, and reduced resource wastage. Modular building is therefore increasingly …

Abstract Modular Building System (MBS) is an emerging offsite construction technique,
which uses prefabricated units, transported, and assembled onsite. In MBS construction …

Steel portal frames were traditionally designed assuming that beam-to-column joints are
ideally pinned or fully rigid. This simplifies the analysis and structural design processes, but …

History has demonstrated that buildings designed to conventional design codes can lack the
robustness necessary to withstand localised damage, partial or even complete collapse …

Socket joints and bolt-ball joints are typical semi-rigid joint systems widely used in spatial
structures. In this paper, tests on fifteen joints are carried out to study their mechanical …

A test series was carried out and reported in a companion paper on the semi-rigid behaviour
of aluminium alloy gusset (AAG) joints subjected to bending moment and axial force. This …

The overall structural performance of multi-story modular buildings is largely dominated by
the joint mechanical properties of inter-and intra-module connections. This paper presents a …

The behaviour of steel joints is complex and requires the proper consideration of a multitude
of phenomena, ranging from material non-linearity (plasticity, strain-hardening), non-linear …

The design-by-analysis approach lays the foundation for the next generation of structural
design standards in which the strength and structural safety check are performed in a single …

In this study, we develop a seismic optimization method to minimize the semi-rigid steel
frame cost. In the proposed method, cross-sections of columns and beams and types of …
