Object of Analysis
The demonstration object to be modelled and evaluated encompasses the corner
region of a masonry and concrete construction over an exterior space (e.g.
carport). As illustrated in the axiometric (axonometric) rendering below, the
masonry bearing wall is bonded with the concrete floor slab along the side which
flanks the exterior space underneath, and supported by a girder spanning an
opening in the other direction.

The standard masonry wall construction is a total of 35.5 cm thick, composed
of (from the exterior):
2.5 cm |
stucco |
30.0 cm |
masonry |
2.0 cm |
interior plaster |
In the region flanking the floor slab, the masonry wall is substituted by:
2.5 cm |
stucco |
6.0 cm |
perimeter brick |
4.0 cm |
perimeter insulation
(floor slab) |
The reinforced concrete girder supporting the other side of masonry is
encased in 7.0 cm of standard insulation.
The floor construction over the exterior space is built up to a total
thickness of 41.5 cm with:
0.5 cm |
exterior plaster |
12.0 cm |
insulation |
0.5 cm |
adhesive mortar |
17.5 cm |
reinforced concrete |
2.0 cm |
sand cushion |
3.0 cm |
isolating underlayment* |
1.0 cm |
embedded heating assembly (concrete)* |
5.0 cm |
concrete topping* |
|
*- expansion strip along outer perimeter (0.4 cm ) |
Despite extensive exterior insulation, such a prominent corner situation
could prove to be a critical thermal bridge. A potential heat source has also
been included to simulate an electrical floor heating assembly in the concrete
topping. The efficiency of such a heating alternative in this exposed location
can thus be assessed as well.
