Why Did My Reinforcing Change in ACI 318-14?

The new ACI 318-14 code has been implemented into RISA-3D V14, RISAFloor V10, and RISAFoundation V8. One of the big changes between the ACI 318-11 and the ACI 318-14 was to minimum flexural reinforcement for one-way and two-way slabs, as well as foundation elements.

Making a Time History Animation Video

Time history analysis solves for normal analysis results (joint displacements, member forces, code checks, etc.) based on loading that varies with time. For some analyses it may be useful to view an animation of the deflected shape of the structure as a function of time. This blog topic serves as a...
