Calculate shear forces, bending moments, and reactions for simply supported and continuous beams under point loads and distributed loads. Includes a step-by-step worked example.

Generate P-M interaction diagrams and check reinforced concrete columns per ACI 318. Covers rectangular and circular sections, strength reduction factors, and a detailed worked example.

Look up or compute geometric and structural properties for standard rolled steel shapes and custom sections. Explains area, moment of inertia, section modulus, and radius of gyration with a W8×31 worked example.

Design and check flexural and shear reinforcement for concrete beams and slabs per ACI 318. Covers required steel area, minimum and maximum steel limits, stirrup spacing, and a complete flexural design example.

Evaluate prestress losses, run service-level stress checks at transfer and final conditions, and verify flexural strength for pretensioned and post-tensioned concrete members.
