3.2 Structural analysis The structural analysis of the proposed G+4 sustainable hospital building was conducted both manually and using Tekla Structural Designer. The building features a reinforced concrete frame system with beams, columns, slabs, and waffle slabs — chosen for their efficiency in spanning large hospital layouts. Initial manual calculations helped determine member sizes, load distribution, and structural behavior under dead, live, wind, and seismic loads, following IS 456:2000 and IS 875:1987 ((IS: 456 (2000), IS:875 Part 1 (1987), IS: 875 Part 2 (1987)). Safety was prioritized by applying appropriate load combinations to ensure stability under various conditions.A detailed 3D model was created in Tekla Structural Designer 2024 for advanced analysis, providing accurate simulations to verify strength and serviceability. The waffle slab system proved effective for load distribution, minimizing shear and maximizing span efficiency. Structural elements were sized and reinforced to meet safety and sustainability standards. Tekla’s results aligned well with manual calculations, adding confidence to the final model and BIM integration, Table 1. Column analysis showed an axial load of 4397.59 kN, major bending moment (Mx) of 245.07 kNm, and minor moment (My) of 181.59 kNm — highlighting the importance of accounting for axial and biaxial forces in design.
