Macorini L, Izzuddin BA, 2013, Nonlinear analysis of masonry structures using mesoscale partitioned modelling, Advances in Engineering Software, Vol: 60-61, Pages: 58-69
This paper presents an effective and accurate computational strategy for unreinforced brick masonry structures. Mesoscale descriptions allow a realistic representation of the nonlinear structural behaviour of URM, but can pose prohibitive computational demands for large-scale problems. To overcome this drawback, the computational strategy presented in the paper employs the domain partitioning approach, which is coupled with an accurate mesoscale finite element model. This allows the effective parallelisation of the nonlinear structural analysis simulation, where significant speed-up can be achieved in the nonlinear analysis of large masonry structures. The potential and effectiveness of the proposed computational strategy are shown through numerical examples, where full-scale masonry structures are considered.
Xavier FB, Macorini L, Izzuddin BA, 2013, Enhanced robustness of multi-storey buildings with unreinforced masonry infill, Pages: 265-275
Previous work at Imperial College London by Izzuddin and co-workers led to the development of a multi-level framework for the assessment of building robustness under sudden column loss scenarios, and highlighted the significant potential contribution of unreinforced masonry infill panels towards arresting progressive collapse for such scenarios. The latter work considered the contribution of infill panels using equivalent struts, which are inherently approximate particularly in relation to the modelling of openings and general interaction with the surrounding frame. Recent work by the authors has focussed on the development of a mesoscale modelling approach for unreinforced brick masonry, which has been incorporated within a partitioned modelling framework to provide an accurate and efficient approach for predicting the response of masonry components under extreme loading. This paper employs the detailed mesoscale modelling approach for brick masonry infill panels, with and without openings, making comparisons against the simplified equivalent strut models. The outcomes from the detailed mesoscale models are incorporated within the multilevel robustness assessment framework to provide a more accurate evaluation of the contribution of masonry infill panels to the structural robustness of steel composite buildings under sudden column loss. It is confirmed that this contribution is significantly large to merit the consideration of infill panels in robustness design and assessment practice, subject to quality control during the construction process.

The paper investigates the dynamic behaviour of partially restrained steel-concrete composite frames coupled with viscoelastic dissipative bracings. A number of time-history analyses have been carried out on a one-storey frame coupled with a viscoelastic dissipative bracing using an advanced numerical model. The purpose of the analyses is to identify the influence of the type of beam-to-column connection and property of viscoelastic bracing on the performance of the hybrid system. The outcomes of the analyses show that the viscoelastic bracing can be used as an effective dissipation system, where the plastic hysteresis of the joints provides a significant contribution to the overall structural performance under destructive earthquakes.
