WORK SAMPLES
FPM41 Office Building
Fig. 1 - Architectural renderings
- Description:
- A 17 storey office building in Lisbon, designed with different materials (reinforced and pre-stressed concrete,
steel, steel-concrete composite elements) and engineering solutions. A 12m long "body" of 16 storeys is suspended by
steel diagonals. Its construction area rounds 37,700 m².
- Main tasks performed on FPM41 Project:
Optimization of the post-tensioned waffle slabs solution using tendon elements in SAP2000;
Design and optimization of pre stressed beams to uniform the vertical loads on the perimeter steel columns in
the main facade of the building, using a plan model in SAP2000;
Development of a 3D model in SAP2000 in order to verify resistance as well as the serviceability stresses in the
perimeter steel columns in the facades;
Dimensioning of all the perimeter steel columns;
Detailing of ordinary concrete elements reinforcements such as slabs and beams.

Hospital da Ilha Hospital Building
Fig. 5 - Architectural renderings of the silo structure
- Description:
- A hospital to be built in Luanda, Angola, designed in reinforced and pre-stressed concrete engineering solutions.
The project has three structures: the main hospital building, a silo based structure for car parking (emergency admissions
department incorporated on upper levels with heliport) and a small technical plant. The total construction area spans
41,200m².
- Main tasks performed on Hospital da Ilha project:
Feasibility study of the slabs solutions both for the main structure of the hospital and the silo structure using
plan models in SAP2000;
Dynamical analysis to evaluate the structural response to earthquakes of the main hospital building using a 3D
model in SAP2000;
Detailing the reinforcement of shear walls and columns of the main hospital building resisting the horizontal
seismic action;
Design and optimization of post-tensioned pre-stressed beams at the entrance of the main building of the
hospital and below the protruding cantilevers;
Detailing of ordinary concrete elements reinforcements such as slabs and beams.

Rua da Bela Vista à Lapa Residential Building
Fig. 13 - Generic reinforcement solution for the floors
- Description:
- A refurbishment project for a luxurious residential building in Lisbon, preserving the stone masonry facades and
using a different variety of materials solutions (reinforced concrete, steel and timber). Total construction area rounds
1,800m².
- Main tasks performed on Rua da Bela Vista à Lapa project:
Dimensioning of steel beams used to reinforce the existing wooden floors, essentially designed to guarantee
deformation control in serviceability;
Analysis of the core masonry walls behaviour due to the demolition of its centre support column and design of
two steel beams to transfer the vertical load to the next columns;
Development of 3D finite model in SAP2000 to evaluate the dynamic behaviour of the structure, and
determine the stresses in the masonry walls, strengthened with a reinforced concrete blade, due to the seismic
action;
Dimensioning of a portico steel structure at the main facade of the building, destined to transfer vertical load
from the masonry wall, due to an opening in it;

Flat Slab Solution Study
Fig. 18 - Generic solution of the flat slab
- Description:
- Preliminary design of a competitive flat slab solution (without beams or strips) for a big construction company in
Portugal, to be used in the construction of big shopping surfaces. It is meant to be competitive in terms of concrete and
reinforcements usage but it was also designed to achieve fast construction timings. A solution of pre-cast slab modules
was considered with the inclusion of a technology of hollow plastic boxes (Cobiax® by FERCA) to minor the slab weigh
in its final stage.
- Main tasks performed on the study:
Design of the pre cast slab modules, conditioned by the weight lifting limits of a fixed crane and also by the
span length during the construction phase (between shoring supports);
Design of steel bar trusses included in the pre-cast modules, designed to guarantee resistance in the
construction phase;
Development of a plan model in SAP2000 to evaluate the slab serviceability deformation in its final stage;
Detailing of the slab reinforcements needed in its final stage using also the same plan model;
Analysis of the slab concrete stresses due to its own weight, after removing the shoring system, in order to
avoid early cracking.
