An investigation into a complex masonry façade

Overview? This report examined a complex masonry
façade for a high profile project in the centre
of London which, Ramboll are currently
investigating. In particular, it sought to
identify the best structural system for this
façade and the buildability of this system. The
complexity of this façade arises from the
elaborate geometry and varying angles and spans
of each of the walls as shown to the left.
Experimental investigations were carried out to
simulate wind loading for the three proposed
different structural systems Mortar, Dowel and
Shear Key. To do this a small panel for each
system was built and the construction times and
complications for each panel were noted. When
construction was complete, horizontal loading was
applied and the failure loads, reactions and
deflections were recorded. Following this, a
parametric model was built to analyse the line of
thrust through the panel. The model was
constructed parametrically so that the angle,
span, load and other variables could be easily
changed and the analysis quickly reproduced for
all scenarios.
Main Outcomes ? From the results obtained it
seems that the dowel system was the most suitable
system overall, this is based on structural
strength and buildability. In addition, while the
parametric model appeared accurate it would need
further testing and more accurate results to
confirm it.
Future Work ?Now further testing is being carried
out on larger sections to test the dowel system
more precisely. This will examine the continuity
of the system over an intermediate support. The
results could also be used to verify the model.
