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.
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.
A method is developed to predict the service stiffness of floor diaphragms in modular buildings.
The influence of diaphragm flexibility on the seismic response of modular buildings is presented.
Performance-based methods for the seismic design of diaphragm connections in modular buildings are discussed.
