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.
