Glass floor design iteration: Aesthetics, structure, and standardized panels were considered
Structural analysis: Glass diaphragm wall and Roof truss component sizing
Using hand calculations the glass walls sizings were calculated and Karamba was used to confirm the structural analysis. The glass diaphragm wall is made up of two 9*3.125 m laminated glass panels and used for the internal and external pane of glass. This size fits the maximum width possible for lamination of glass which is 3.2 m. The karamba model consists of a pinned connected roof space frame, loaded by point loads that simulate the dead load of roof decking and cladding. Th roof is pinned connected to a beam attached to glass facade boxes that are clamped from the top and bottom. A wind load of 1kN/m2 is applied to the facade, and no maintenance loads are in place. Th resulting utilization factor for stresses resulting from bending does not exceed 10%. Maximum deflection occurs in the corner glass boxes, which bear the highest wind load due to their location and larger size compared to the rest of the boxes. The utilization factor for stresses is within the acceptable range, and the deflection is lower than expected.
The roof space frame has been optimized in terms of circular hollow section (CHS) size, using members made of 7020 aluminum alloy. Th maximum allowable deflection was set at 8cm at the center of the roof, which was loaded by wind loads and dead loads from the roof cladding and decking. To ensure ease of assembly and production, the number of allowable member ties was limited to three. Th Karamba component “optimize cross-section” was used to perform the optimization. Th resulting section dimensions are as follows: CHS 33.7 / 3.2, CHS 60.3 / 3.2, and CHS 60.3 / 3.2. Th use of a limited number of member ties facilitates ease of assembly and simplifies production processes
Safety
The structural safety analysis performed in Karamba on the façade structure with dead loads and a the wind load applied yielded positive results. The analysis showed that the building was able to maintain its structural integrity under different loading scenarios, even when several glass boxes were missing. Even in the third case where four corner boxes were missing, the building remained structurally sound and did not collapse or suffer any structural failure.
The stress distribution analysis conducted alongside the structural safety analysis revealed that the higher stresses could be observed in the areas adjacent to the missing boxes. Additionally, the beam connecting the roof to the façade underwent strong stresses and deflections resulting from the load of the space-frame. However, the overall stress levels remained within the acceptable range for the materials(Glass and steel).

Research project description.
Setting up the experiment
The study involves a novel experimental campaign to assess volunteers’ levels of perception and acceptance of various glass deformations. The glass was deformed using a bespoke electro-pneumatic system at levels corresponding to below, above, and at the current serviceability limit. To insure safety of experiment , a break test was performed using similar IGU (1470x950) and the data collected was compared with FEA in Ansys to set a safety threshold for the experiment. The Electro-pneumatic system was able to deflect the IGU in a cyclic motion mimicking movement during a wind load.
Statistical analysis of survey conducted during experiment and design implications.
During the experiment participants response was recorded using questionnaires. The results demonstrate the feasibility of measuring human responses to deformations in the glazing and provide essential data for setting serviceability limits. The experiments and corresponding user satisfaction feedback indicate that the current serviceability limit of L/50, may be relaxed, thereby presenting opportunities for material efficiency, such as the adoption of thinner glass in facades. The methodology effectively captures human responses, revealing that changes in reflection were the primary reason for the perception of movement, leading to a higher perception of glazing movement and a lower acceptance at night. Overall, participants felt safe regardless of their prior knowledge on glass properties, and providing this information to participants did not improve acceptance, which was already sufficiently high. The findings from this research fill an important knowledge gap in understanding user acceptance of glass deformations, crucial for comprehensive user satisfaction assessments and evidence-based reductions in glazing thickness.

Project Location:Djibouti.
Project Involvement:
The schematic design was done by MEZZ DESIGN BUREAU(Italy).I was involved in the preliminary and final design development which included floor plan modification, interior design,modeling,rendering and a preliminary proposal to a sustainable approach to the facade already done in preliminary stage.
Facade sections
A development of the interior of the IGAD HQ to reflect the cultural elements of the East African region and a modest approach to making a comfortable space with a functional layout and orientation.Involved in designing ,rendering and drawing preparation.
As the daily heat and humidity of Djibouti makes it difficult for opening a window for ventilation,MEZZ DESIGN BUREAU have proposed an exterior shade and an active artificial ventilation. This approach plummeted the energy consumption as the full glazing of the building increases the temperature load on the AC system.
During the preliminary phase ,we have proposed for a double facade system which optimizes the underground aquifer to cool air and circulate around the building. An approach to decrease the energy consumption of the building and a provide a sustainable ventilation system.
