what is your opinion in layout of tendons for this post-tensioned slab???? notes : spacing = 1.5 m max span = 9 m , slab thickness= 250 mm each tendon contains 5 strands (12.7 mm) can you suggest span layout to design sections????

Does ram concept give the elongation after stressing and removing of the jack or it gives the final effective elongation after seat loss ( 6 mm) In other meaning, what is the elongation that the designer types in the pt drawing, and the site engineer…

Hi, I have a question about the RAM Beam and Frame design. Do they complete each other or they are the replacement? The reason I am asking this question is the model that I have with Bent beam. The beam connects the top level to the mid level. If…

Hi, Hopefully someone can answer this. I created a concrete structure using STAAD.PRO CONNECT EDITIONs PHYSICAL MODELLER Workflow. Then after that I also analyse it using the same software. Save and close the file. To finish my design, I opened it…

When i start any design as a new then i chose the section and assign with base plate, after that i go to edit then chang the dimensions and loads bit when i want to chose bolt 8mm I didn’t find it please advise

In HSS knife plate connection, the check of Tee stem tensile yielding takes the length of weld 12" even though the length of connection entered is 20". Please advise. That's to say it does not consider any length entered more than 12" for HSS10x10x5/8…

Does RAM SS consider all the stories where I have the unreduced live load for the calculation of the tributary area that is considered for the live load reduction? Design per ASCE 7-10.

Hi, when i try to model pt flat slab and using different concrete grade (40 for pt slab and 30 for column, wall and conventional beam) there shows an error inconsistent concrete. Is RAM concept cannot model in different concrete grade?

Hey I'm trying to apply a moment line load (kips). I want to how does the program interpret it ? Or can I just apply a point moment (kip-ft)? Whats the difference between those two? Also, the moment I have is for the basement wall that is 220' long…

In Single plate connection to HSS, while checking punching shear on the HSS column support, RAM takes the lp (length of connection) as the width of the shear plate instead of the length. Please advise. Snapshots are attached for easy reference.

In HSS truss connection when checking sidewall local yielding In-plane and Out-plane to rectangular HSS, the Zb (Plastic section modulus) is taken the same for both in-plane & out-plane.

In checking the bolt shear in the gusset side (in HZ bracing), bolts are subject to double shear while in calculations it is calculated as a single shear. Please advise.

Is there any code limitations regarding welding the gusset plate of a horizontal bracing connection to the beam web directly? (Because RAM does not allow welding the gusset directly to the beam web but it allows it to the beam flanges)

How does RAM frame handle joint stiffness reduction when analyzing a steel moment frame? I have a structure with steel moment frames and would like to explore the option of using flexible moment connections. What is the process of reducing joint stiffness…

I'm trying to design a mat foundation. When I run the calcs I'm getting this warning as in the pic above. Does anyone know if this is concerning? The deflections are around 0.78" for D+L load case.

I have modeled a square one-way slab supported by 4 walls with 'other' material and have applied a surface live load of 40 psf. Theoretically, I would expect that only two walls would take all the load from the slab, but, both RAM Frame and RAM Concrete…

I have a few questions regarding CMU walls in RAM SS. How are CMU shear walls handled in RAM structural system to obtain lateral load distribution? I have a steel structure with exterior CMU walls which I want to use as shear walls. The CMU shear walls…

Good Everybody, I am Modeling a Circular Digester tank of 318Million Litters per Day , I have a doubt how to model the connection between the wall and raft footing. this how I modeled the Raft is 600mm thk and the wall is 350mm thk, I have modeled…

Dear sir, after design I got output design report that very much congested and complicated. Can I get out only for Beam & Column in excel format. please suggest if we have any method. Thank you.

Hey I'm designing a mat foundation. I am getting an error of Incompatible design and load combos. I'm not able to understand what's wrong. I defined my own load combinations. Is that the reason?

Hey I'm designing a mat foundation. I see two types of analyses zero-tension and linear. What is the basic difference between two? I read the manual but couldn't understand clearly. It would be great if anyone could explain it to me in layman language…

Can Ram concept be used to design a monolithic Slab-on-Grade (BRAB) Foundation? These foundations are widely used in Texas, and the WRI (Wire Reinforcement Institute) has a design aid which I am following, but would like to use Ram Concept and would like…

Hi All, Need a quick solution, as I am getting following error when doing Vibration analysis on Ram concept with Eurocode. I am doing both column and wall compressible as standard practice.

Does anyone know of a beam tag that can access the information that imports from RAM Structural System? I would like to access the following in order to tag on plans: Beam Size, Top of Steel Elevation, Camber Size, Number of Studs, Start Reaction, Start…

WHEN I USE RAM ELEMENTS, IT WORKS PERFECTLY TILL I HAVE TO PROCESS. THEN IT APPEARS "AMD PROCESATORS... TRY THE DIRECT SOLUCIONATOR" OR SOMETHING LIKE THAT. I KNOW MY LAPTOP USE AN AMD INSTEAD A CORE I, WHATS SHOULD I DO?
