Construction Period 10/2014 - 10/2015
A six storey residential building with commercial spaces on the ground
floor and a basement car-park.
The building has been designed as an in-situ reinforced concrete frame
comprising: basement level, five storeys above ground over a footprint
of approximately 300 m
2
. Ground conditions at the site required the use
of a continuous secant piled perimeter retaining wall. The secant piles
carry permanent loads from the perimeter columns above ground, with a
continuous reinforced concrete capping beam to transfer loads between
the columns and piles. The set-back fourth storey and flat roof will be
constructed in light-gauge steel framing, designed and installed by a
specialist sub-contractor, so was modelled only as applied loads onto the
fourth floor slab. These loads had to take into account a request from the
client to allow for future expansion of the lightweight structure to include a
fifth and a sixth level.
We used SCIA Engineer to perform a comprehensive structural analysis of
the building, taking into account different situations that may occur during
construction and after: soil interaction, connection with the piles, hydrostatic
pressure on the raft, deflection, applied force/stresses on elements, and
reinforcement design for 1D and 2D elements. The user-friendly interface
and flexible structure of the program allowed us to adapt and implement
the changes in a very short space of time.
