Comparative Design of RC Frame and Steel-Metal Deck Schemes for a Building with Basement Water Tank and Uplift Constraints

This solution provides a comparative analysis of two structural schemes: a reinforced concrete (RC) frame with shear walls and a structural steel frame with metal deck flooring, designed for a building incorporating a basement water tank.

Critical engineering challenges addressed include differential settlement across varying clay strata, buoyancy and uplift forces during flooding, and fire protection. The design utilizes tension piles for uplift mitigation and battered back construction for basement tanking.

Included calculations cover wind loading, shear wall design, basement slab reinforcement/deflection, and retaining wall stability. Deliverables feature detailed structural plans (Levels 1-4), elevations, section details, load run-downs, and a comprehensive construction method statement and programme.
