    • Holistic Considerations for Low-Rise Building Design 

      Holland, William; Gray, Caleb; Loporcaro, Giuseppe; MacRae, Gregory (2024-04-09)
      Two low-rise residential structures, a single-storey residential structure (SSRS) and one triple-storey structure (TSS), are initially described using building information modelling (BIM) software. The structures are then ...

    • Multistage Friction Connection Optimisation 

      MacRae, Gregory; Brosnan, Ruaidhri; El-Mashalgi, Bader; Luo, Zheng; Chanchí Golondrino, Jose; Coral Potosí, Hugo Anderson (2024-04-09)
      This paper describes the use of multi-stage friction connections (MFCs) to modify hysteresis curve characteristics of structures in order to decrease their peak and residual displacements. Both cases with and without P-delta ...

    • P-delta or P-theta analysis? 

      MacRae, Gregory; Dehghanian, Seifollah; Moghadam, Abdolreza (2024-04-09)
      Engineers have methods to estimating the displacements of inelastically responding structures in earthquakes. Rules to estimate such displacements for a structure with a certain period, damping, and hysteretic behaviour ...

    • Panel Zone Strength in Moment Frames with Slabs 

      MacRae, Gregory; Macalister, Ed; Henderson, Cameron (2024-04-09)
      Despite the common occurrence of composite slabs in steel structures, they are often excluded from design considerations, which may lead to undesirable panel zone yielding due to increased demands. Through the utilisation ...

    • Seismic Ratcheting Considerations 

      MacRae, Gregory; Hussain, Mereen (2024-04-09)
      This paper describes recent research conducted to understand the effects of structural characteristics on the seismic response of single storey structures with a ratcheting tendency. The ratcheting tendency was characterised ...

    • Seismic response of frames with building cladding elements 

      Edwards, William; Robertson, Jesse; Luo, Zheng; MacRae, Gregory (2024-04-09)
      This paper presents the concept, methodology and findings of the analysis of frames with building cladding elements exposed to seismic events. Inelastic nonlinear push-pull analyses, and hand analyses, are conducted to ...

    • Seismic response of sustainable, resilient eccentrically braced frames 

      Hasanali, Maryam; Andished, Kaveh; Taheri, Hafez; Mago, Nandor; ShahMohammadi, Amir; Karpenko, Michail; Jarmai, Karoly; Dong, Pingsha; Clifton, G. Charles; MacRae, Gregory (2024-04-09)
      “Circular design” and “Construction 4.0” are two distinct concepts that can be complementary and beneficial within the construction industry while prioritising sustainability. Nascent global Construction 4.0 knowledge ...

    • Simple Three-layer Pagoda Analysis 

      Liang, Haoyu; Chen, Jian; MacRae, Gregory; Jia, Liang-Jiu; Li, Minghao (2024-04-09)
      This paper describes the construction of a simplified three-storey pagoda and its behaviour. The following are developed: (i) a 1/20 scale 3-D printed overall structure model, (ii) a 1/10 scale 3-D printed model of one ...

    • The ROBUST Steel Building Response 

      MacRae, Gregory; JIA, Liang-Jiu; Yan, Zhenduo; Clifton, Charles; Ramhormozian, Shahab; Dhakal, Rajesh; Xiang, Ping; Rodgers, Geoff; Quenneville, Pierre; Zhao, Xianzhong (2024-04-09)
      The ROBUST test programme describes the full-scale shaking table testing of nine different steel frame building configurations on the Tongji University shaking tables. Energy dissipation occurs by means of friction devices ...
