7.1 Design Limitations
The design of the RC beam & slab of the zone Z is carried out here in theis project. All the designs are matched with the AS3600-2009. The primary assumption at the beginning of this design is that the beam is considered as simply supported rather than continuous. This resulted in having an over-reinforced section (He et al. 2023). This is founded on an approximation that fails to consider the fact that there is an increase in the quantities of moment redistribution in continuous systems and this might lead to 15-20 percent beyond continuous achievable in steel. The other drawback is on load assessment methodology. The principle underlying the consistency of introducing the critical jacuzzi load (30.04 kN/m2 ) on the entire 1st slab panel is not physical as the loading of water is localised in some areas. Additionally, the calculation of the tributary area requirement that the stress transfer to the beam was uniform simplified the complex patterns of stress equally on the beam of the one-way slabs. Satisfying the criteria of strength, the cement mixture can be overdesigned in terms of exposure conditions. The desired 40.5Mpa average strength and the desired 8.5Mpa safety margin does not appear appropriate to the A2 exposure category and thus the the possibility of optimising the material without the necessity to cut performance is possible.
7.2 Potential Design Improvements
The changes that it needs are some expansion to make it more structural and economically viable. By performing actual continuous beam analysis (moment distribution, or finite element calculation) of the structure, the internal forces would be more precise and reinforcement would be minimised by 10-15 percent (Zhu et al. 2024). This may allow the region to utilise better material by adjusting the variable slab thickness deeper where the momentation is high.
Important improvement areas include use of load models. Other than providing the maximum load everywhere, it would also result in design actions much more realistic by using deviations in load between and within different functional areas. New analysis whereby time effect and construction sequence have effects on physical and mechanical properties of material, which are long lasting would enhance prediction of long term performances.
Optimization techniquesSTR would be applied to the enhancement of the reinforcement scheme with respect to serviceability and, conversely, strength as well. The current design currently relies highly on minimum reinforcing provisions that, even with policing of the crack may not yield ultimate cost savings (Alshamrani et al. 2023). There are other types of reinforcement like spacing of bars, which should be employed more frequently in high strength steel in key locations to make the structure smarter.
