Earthquake Beams – ACI 318-25

This application assists in the shear design of earthquake-resistant beams according to the ACI 318-25 Code, specifically Articles 18.4 and 18.6. The design is based on the actual flexural reinforcement, following the principles of capacity design commonly applied in seismic engineering.
By using the real flexural capacity as input, the app calculates the required shear reinforcement to ensure ductile behavior and compliance with international seismic standards. It supports metric units (SI) and is suitable for both design and verification tasks during structural project reviews.
In addition to its practical use in engineering offices and fieldwork, the app serves as an educational tool for civil engineering students and instructors, helping to reinforce key concepts in seismic beam design and capacity-based detailing.
Whether in professional practice or academic settings, this tool delivers clarity, precision, and confidence throughout every stage of seismic shear design.
