Abstract

Modular construction is a relatively a new form of high-rise construction, which involves the assembly of prefabricated structural modules. In contrast to traditional on-site construction methods, it allows for parallel processes to occur where the modules can be manufactured offsite, before or during preliminary on-site works, and then be transported to the site and assembled progressively. However, modular construction raises some concerns, such as load-bearing capacity and structural integrity, in comparison to traditional in-situ construction. Hybrid construction processes may also be required in order to satisfy load capacity requirements, particularly for high-rise buildings. Structural integrity must be fully engineered into the modules during the early design processes and include consideration of manufacturing, handling, transportation and lifting issues as well as their long-term post-assembly integrity. Structural integrity may also need to encompass the capacity to resist seismic forces for buildings constructed in earthquake-prone areas. The purpose of the paper is to specifically examine how the overall structural integrity is maintained through the use of modular construction. Moreover, the main aim of this paper is also to investigate the structural integrity of modular construction specifically for high-rise buildings. Finally, this paper will examine how the panels maintain their structural integrity in the module itself and in the overall structure.
