Modular construction which involves the assembly of prefabricated structural modules, is a relatively a new form of high-rise construction; directly opposing the traditional on-site construction methodology. It allows for a parallel processes to occur where the modules have the ability to be manufactured whilst the site works can commence. More recently, Modular construction has proven to be innovative and successful alternative method of construction to the traditional method of concrete and column construction. However, this method possesses many new obstacles such as load bearing capacity and structural integrity in comparison to the traditional construction. The main ways to preserve Modular construction’s structural integrity (especially for the high rise buildings), needs to be undertaken via the methodical and detailed engineering processes, and during the design stage at the beginning of the modular process. Likewise the utilization of hybrid construction (i.e. to use both traditional and modular construction together in buildings) may also be required in order to meet the project’s specific limitations including additional load capacity requirements. Although, structural integrity is not generally compromised by the use of modular construction, on the other hand seismic loading creates significant internal forces on materials. Therefore with increased modular construction being utilized, it is fundamental that these innovative design methodologies be able to accommodate for such magnitude of forces.
Although the available literature on the modular structural integrity is limited, a qualitative methodology is more appropriate to be adopted rather than a more conventional quantitative. 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.
