ABSTRACT In response to the challenges faced by post-disaster construction, the present study endeavours to offer an improved solution in a practical manner. To this end, a critical analysis of modular systems that can be employed in post-disaster construction is conducted, which is succeeded by the set of required features. Considering these features, a system based on modular prefabricated components (MPC) is presented, which effectively eliminates all hitches while demonstrating facilitated solutions. From a practical standpoint, a comprehensive description of the structure’s dimensions, assembly steps and design constraints are proffered, accompanied by primary structural analysis factoring in the highest risk categories. The applicability and limitations of the system in post-disaster scenarios are also discussed in comparison to other modular construction methods. The findings indicate that the system exhibits high levels of disjoint-ability and collectability, flexibility and customisability, developability and repairability, in addition to being cost- and time-efficient. Furthermore, it demonstrates a favourable response to the predicaments posed by post-disaster situations, such as logistics, construction process, safety, seismic behaviour and environmental effects. Overall, this research highlights the applicability and potential of MPC systems in post-disaster construction and delivers a valuable output for policymakers, managers, architects and engineers involved in this regard.

ABSTRACT Base isolation is a low-damage seismic design strategy that can be used for constructing resilient structures. Geotechnical seismic isolation (GSI) is a new category of emerging base isolation techniques that has attracted global interest in the past decade. Research on GSI based on rubber-soil mixtures (RSM) has focused on structural performance under earthquake actions, whilst there are concerns over the serviceability limit states (SLS) requirements in relation to (i) human comfort under strong winds and (ii) ground settlement under gravity, which may induce cracking and durability issues in structures. This article presents the first study on the serviceability performance of buildings constructed with the GSI-RSM system. The finite element model of a coupled soil-foundation-structure system has been validated by data recorded from geotechnical centrifuge testing. The numerical estimates of ground settlement have also been compared with analytical predictions. It is concluded that the GSI-RSM system can satisfactorily fulfill the SLS requirements.

ABSTRACT This paper reviews previous research and current practice in timber connection design in Australia with reference to methods of deriving design information from test data for nails and screws. The two key documents for timber connection design in Australia are AS 1720.1 design of timber structures and AS 1649 test methods and evaluation of timber connections. These documents have a long history of development, with major changes in design methodologies – from deterministic working stress design to probabilistic limit state design. The supply chain for timber connections has changed with a reduction in the utilisation of timber species and an increase in new fasteners developed for specific purposes. A new approach to the design of timber connections has been proposed to cope with the changing situation. The review is of historic interest but also to ensure that the proposed new approach is consistent with past developments.

ABSTRACT Stiffness properties of structural members, such as beam, plate and shell, can change drastically in the presence of axial forces due to geometric effects of the nonlinear strain components. In this paper, the stability behaviour of beam-column is investigated using the governing differential equation and compared with the geometrically nonlinear finite element analysis. The lateral deflection obtained from the theoretical model matches quite accurately with the numerical values for wide range of axial to critical load ratio P/P cr . It is shown that bending stiffness decreases linearly with the axial load. By extending the theory, an expression for the membrane stiffness of the beam-column is presented in this paper. The geometrically nonlinear finite element analysis can capture exactly the parabolic variation of the membrane stiffness as per the derived expression. It increases initially up to P/P cr = 0.35 and decreases rapidly to negligible value near the critical load indicating buckling instability.
