Minimum extensions for deformed reinforcement. This change applies to cracked deflection calculations in the program where fr is used to calculate cracking moments, Mcr. (ACI 318-19, 7.6.1.1)įor two-way non-prestressed, reinforced concrete slabs the equation for modulus of rupture is modified for fy exceeding 80,000 psi. Minimum flexural reinforcement for non-prestressed, reinforced one- and two-way slabs shall meet a minimum area of flexural reinforcement of 0.0018Ag. Reinforcement strain limit has been revised for all criteria and system types (beam, one-way and two-way slabs for RC and PT mode). Provisions found in the latest design standard that have been included in ADAPT-Builder include: The 2020 version includes applicable code provisions from ACI318-19: Building Code Requirements for Structural Concrete. ADAPT-Builder v20 has been updated to ensure that users can take advantage of designs conforming to the latest building code standards.
