This presentation discusses structural design. Structural design applies math and science concepts to design structures for stability and sustainability. The structural design process involves several steps: 1) The architect designs the building layout. 2) The structural engineer designs the structure to fit the architecture and chooses structural systems. 3) A general layout is developed considering loads, material selection, and cost. 4) Loads are calculated and stress analysis is performed. 5) Structural elements are selected. 6) Drawings and specifications are created. 7) Approvals are obtained before proceeding to construction. Structural drawings use different scales and show dimensions, lines, and projections to convey design details.
