Development and optimisation of low-carbon, affordable, medium-rise modular structural system using innovative connections

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. In Australia, having an urban population of approximately 21 million, equivalent to 90% of the total population, the...

A review on diaphragm behaviour and connections for multi-story modular buildings

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.

Field performance of geopolymer concrete structures

A major barrier to the adoption of Geopolymer concrete in construction is the lack of long-term performance data. Field testing has been undertaken to determine the behaviour of geopolymers in different service environments and address the gaps in knowledge. The University of New South Wales...

Numerical study on the effects of diaphragm stiffness and strength on the seismic response of multi-story modular buildings

Highlights 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. Abstract

Durability performance of precast fly ash–based geopolymer concrete under atmospheric exposure conditions

This study investigates the durability of precast fly ash–based geopolymer concrete (GPC) exposed to an outdoor atmospheric environment for 8 years. Core specimens from GPC culverts are tested to determine the effect of carbonation, permeation properties, and poresize distribution, and the durability is compared with...
