Structural Analysis Beam Bending Moment, Shear and Deflection Calculator Reactions, shear and bending moment diagrams and elastic deflection for a single-span beam, across thirteen standard load cases — simply supported, cantilever, fixed at both ends and propped cantilever. Statics Reinforced Concrete Concrete Beam Deflection Checker Immediate and long-term deflection of a simply supported reinforced concrete beam, using the cracked effective stiffness, checked against the limit for the member category you choose. ACI 318-08 beta Materials & Quantities Concrete Test Cylinder Calculator How many strength test sets and cylinders a pour requires, and whether the results that came back satisfy the acceptance criteria. ACI 318-08 BNBC 2020 beta Materials & Quantities Concrete Volume Calculator Concrete quantity for slabs, footings, beams and rectangular or circular columns, with a waste allowance and a bag count for small pours. Quantities Foundations & Geotechnical SPT Bearing Capacity Calculator Allowable bearing pressure for a spread footing from a borehole log — settlement-controlled in sand, three published Nc methods compared in clay — with the seismic site class from the same data. BNBC 2020 beta Steel Design Steel Beam Size Calculator The lightest AISC W-shape that carries a uniformly loaded simple span in flexure, shear and deflection, by LRFD or ASD, with the next heavier options that also work. AISC 360-16 beta
