Centroid Stress Plan inaccurate compared to hand calc P/A
Gueorgui Ivanov
For context working on a 8in PT slab. In the banded direction in my interior bays I have 24 strands (26.8 kip/strand) for a trib width of 29 ft. Thus I have a stress of 230 psi (24'*26.8kip/ft / (28'*12*8")). When I look at Centroid stress plan under…

Modelling an Elevated Slab as Plates in combination with Floor Diaphragm Command
Alain Torre
Good day. I understand that for rigid diaphragm slab action, you are NOT required to model the slab as plates if you are to use the Floor Diaphragm command. But for this frame structure that I am working with, there are certain floor loads that…

Two-Way and One-Way Slab Modeling
Eric Feuge-Miller
In RAM SS, I've previously come across a "Fatal Error" in RAM Frame. This prevents the program from opening Frame, and the cause is related to two slabs in the model. Both are One-Way slabs that are supported on one side by a continuous beam, and by a…

SLAB LOAD COMBINATIONS ARE NOT LOADED IN RCDC
Ignacio Rojas
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…

Trimming Design Strips: Ram Concept 2-Way PT Slab
Eric Feuge-Miller
Given the layout of strips, in odd configurations due to irregular structural geometries, is it in y'all's opinion reasonable to review the original strips for any code-related failures (i.e. shear or tension) and make the proper adjustments to the PT…

STAAD - Modeling a Slab - Why I am getting a lower moment?
Akam
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…

How do I analyze the Slab Loads on this?
Sidharth Reddy
I have attached a picture of a plan where a clear head room without beams is to be provided. G+3 building with common portal frame. I am unable to assign floor loads as there is no closed boundary.

How does STAAD determine beam deflections?
Pascual Mauricio
Hello, I am modeling a floor slab (1 ft thick) with concrete beams (all 24" wide x 36" deep). These beams will be cast monolithically with the floor slab, therefore the beams are modeled as 24" deep. My question is how does STAAD determine the following…
