In this paper, the characteristic requirements for inter-module connections with regard to structural and functional needs are identified and presented. An overview into few key aspects regarding multi-story modular building construction is also discussed.

Highlights

Modular buildings are those built using prefabricated volumetric units called modules. Due to modules being connected to each other at discrete locations, discontinuous structural systems are formed, where diaphragm discontinuity is a key issue and could result in diaphragms that are flexible.

Due to the increasing rates of urbanisation and the ever growing urban population, it is inferable that the demand on multi-story construction industry will continue to increase.
