Proposed Villa Shanzu House Extension

Project Details

This project involves the comprehensive structural design and engineering for a multi-level house extension and a detached pavilion. The structural scope includes a robust foundation system featuring independent reinforced concrete pad footings (F1-F6), wall footings (WF1), and tie beams designed to support an integrated hybrid of concrete and steel assemblies. The primary framework utilizes reinforced concrete columns (C1-C6) and a complex beam network (B1-B7) alongside high-strength structural steel components, including Universal Columns (UC 203×203 and UC 305×305) and 127x65x16 roof purlins. The engineering design integrates 140mm thick load-bearing and non-load-bearing masonry walls within the concrete frame, utilizing vertical reinforcement and horizontal joint reinforcing every three courses for structural integrity. Detailed analysis was performed for complex steel connections, which employ 8mm and 10mm thick end plates, flange plates, and gusset plates secured with M12 8.8 high-strength bolting systems. To ensure lateral stability against environmental loads, the structure incorporates SHS 50x50x4mm steel cross-bracing. The architectural elevations define a multi-story profile with the ground floor at 0mm, the first floor at 3000mm, and a total roof height reaching up to 6000mm.

Role

Structural Engineer/Designer

Services Provided

The scope of services included the preparation of structural analysis and structural drawings for the proposed structure. Structural analysis considered applicable loading conditions, including wind, seismic, dead, and live loads, in accordance with governing building codes and site requirements. The work involved the structural analysis and design of all primary structural elements, including foundations, shear walls/core walls, load-bearing walls, columns, beams/girders, roof framing/trusses, and connectors to ensure adequate strength, stability, and continuous load transfer. The services also included the preparation of structural drawings consisting of the foundation plan, roof framing plan, shear wall/core layout plan, structural building section views (longitudinal and cross-sections), framing elevations per gridline, and typical structural details, notes, and specifications necessary to clearly communicate the design intent and support coordination, permitting, and construction implementation.
