Chevron Buckling Restrained Brace Frame Seismic Behaviour Considering Out-of-Plane Effects
Simpson, Toby; Donald, Andre; MacRae, Gregory (2023-04-19)This project evaluates the behaviour of buckling restrained braces (BRBs) in a chevron configuration considering IP and OOP frame deformations using software capable of second-order inelastic frame analysis. Initially a ... -
Comparison of New Zealand standards used for seismic design of concrete buildings
Fenwick, Richard; MacRae, Gregory (2009-09-30) -
Design Considerations for Buckling Restrained Braces in Timber Frames Subject to Out of Plane Deformations
Dorrance, William; Huang, Matthew; MacRae, Gregory; Bashiri, Mehdi; Li, Minghao (2023-04-19)The introduction of using steel buckling restrained braces (BRBs) has proven to greatly improve the in-plane seismic performance of timber structures. However, little is understood about the performance of BRBs subject to ... -
Developing Construction 4.0 transformation of Aotearoa New Zealand's construction sector
Andisheh, Kaveh; Karpenko, Michail; MacRae, Gregory; Chang-Richards, Alice; Clifton, Charles; Moaveni, Babak; Eftekhar Azam, Saeed; Heinzel, Holger (2023-04-19)Aotearoa’s construction industry reached over $20.5 billion in 2019 and it became the fourth largest workplace in the year ended June 2021, significantly contributing to New Zealand’s economy. However, it has long been ... -
Diaphragm axial capacity for external diaphragm connections (EDCs) in square CFST column structures
Tjahjanto, Helmy; MacRae, Gregory; Abu, Anthony; Clifton, Charles; Beetham, Tessa; Mago, Nandor (2019-09-30) -
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 ... -
Interpretation and evaluation of NZS1170.5 2016 provisions for seismic ratcheting
Saif, Khaled; Yeow, Trevor; Lee, Chin-Long; MacRae, Gregory (2022-09-01) -
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 ... -
Multistage Friction Connections
Chanchi Golondrino, Jose Christian; MacRae, Gregory; Coral Potosi, Hugo Anderson (2023-04-19)Multistage friction connections (MFCs) are bolted connections for dissipating seismic energy while reducing peak displacements and encouraging recentring. MFCs comprise two symmetric friction connections co-linearly ... -
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 ... -
