  • SLAB LOAD COMBINATIONS ARE NOT LOADED IN RCDC

    Hello, I have modeled a wall that rests on a slab on four beams and when going to the RCDC I do not see the option of being able to load the slab with the load combination created in STAAD, which is, by the way: All I see in RCDC is this: Instead, as…
  • STAAD - Modeling a Slab - Why I am getting a lower moment?

    Hello, I am new to STAAD and this forum, and this is my first post! I wanted to model an 8.67' X 31.5’ Slab with a 16,000 lb. load applied at the center. The slab will have fixed ends at all sides. As a “one-way slab”, the expected max moment utilizing…
