モーメント抵抗計算機

A moment resistance calculator determines the bending moment capacity of a reinforced concrete slab section under ultimate limit state (ULS) loading. It uses standard flexural design formulas (such as in BS 8110 or Eurocode 2) where the moment capacity is calculated as a function of the reinforcement steel area ($A_s$), yield strength ($f_y$), and the lever arm ($z$).

This calculator is specifically calibrated for singly reinforced concrete slabs with a standard steel yield strength (e.g. grade 420 or 500 N/mm²) and assuming a standard lever arm limit of $0.95\cdot d$, offering quick structural estimation for engineers and designers.
