Design of transfer slab structures for shear, Jiayu Long
Transfer slabs are widely used in multistorey buildings to support planted columns where architectural requirements lead to changes in the column layout between floors. The design for shear at offset columns is complex, with potential failure modes including punching shear, linear shear and a combination of both.
This presentation will discuss the design of transfer structures with clear gap between planted column and adjacent supporting column of at least twice the slab effective depth. Reference will be made to both EC2:2004 and EC2:2023. Comparisons will be made between upper column failure loads determined using nonlinear finite element analysis with 3D solid elements and EC2 with shear field analysis. Based on these comparisons, practical design recommendations will be made.
Bankside Yards West - Opus, Christian Tygoer
Bankside Yards is a major mixed-use development on London’s South Bank, delivered in multiple phases. The masterplan comprises nine buildings, incorporating residential, office, retail, and public realm spaces. The site spans two plots: Bankside Yards West and Bankside Yards East.
This presentation will focus on the design and construction of the basement box within the Bankside Yards West development, and Opus, the residential tower comprising of 53 storeys, including four basement levels.
One Nine Elms, Pawel Gryba
One Nine Elms is a landmark mixed-use development situated near Vauxhall Circus. It is characterised by its two sleek, glass-clad towers, the tallest of which soars to 208m over 58 storeys. The development combines residential, commercial, and leisure spaces into one dynamic urban oasis.
This presentation will focus on the design of two towers and the complex basement and foundation structure. It will discuss the key engineering challenge of the project: the design of the foundation atop a scour feature and two-storey basement, while integrating a large Victorian trunk sewer at a high level.
