Hi
I never used STAAD before, but I used a lot of other similar software (SAP2000, ETABS, RFEM, Autodesk Robot, SCIA etc.). The thing is I might have to use it in the nearest future. Watched a couple of videos online about it. From the 1st look STAAD's GUI is like from the previous decade or...
Hi
Are here factory guys who worked with CFHS columns?
Can you tell me how rebar cages are usually fixed within concrete filled hollow section (CFHS) columns to achieve the required concrete cover between the reinforcement and inner surface of the hollow section? As far as I am imagining the...
Hi
I were wondering for a long time what is the most efficient way to model/design a steel beam with full depth end plates in regard to total assembly length tolerance? EU steel code states that fabrication tolerance is +/- 1 mm for a beam with end plates for full contact bearing. I have always...
Hello
I will talk about Eurocode (EC) provisions in relation to the topic, but most likely other codes have similar provisions too.
Acc. to EC1-1-2:
1.5.1.12
member analysis (for fire)
thermal and mechanical analysis of a structural member exposed to fire in which the member is assumed as...
Hello
Let's pretend that exist a fixed cast-in-place beam 48 m long that is for 100% restrained axially on the ends (externally restrained). From the start of existence the beam is loaded by a load that makes the beam cracked. So it is pre-cracked. The beam starts to shrink and little by little...
Hi
It is common practice to analyse/design continuous slabs separately from building model in FEM. It is clear and easy when gravity load-bearing system (columns and walls) is the same on all stories or changes relatively uniform along height of building. But what if location of bearing...
Hi
Have the wildly used detail in the country where I am working. This is stainless steel tube embedded into the concrete slab. The slab is one-way simply supported. Usually couple of those tubes holding end of the slab.
No scientific works related to behavior of the connection are here in...
Hi
Is it required to make saw cut control/isolation joints around heavy partition wall (block wall in my case)? Searched all around in codes and/or books, didn't find anything

Hi
Quite a while, requirements to minimum rebar bending mandrel diameters have been changed in standards of my country. Let's say for 12 mm diameter rebar, it has been 4*12=48mm and now it is 4.5*12=54mm [spineyes]
Usually rebar bending companies have set of old mandrels for their bending...
Hi
Just in the sake of curiosity. My head goes round a bit from number of terms in English for practically identical structures.
As I see it:
Truss - assembly of members (commonly triangulated) where the members are organized so that the assemblage as a whole behaves as a single object
Beam -...
Hi
Designing a slab on piles. The slab has downward thickenings under heavy/load-bearing walls and on edges. Some sort of these, but larger [smile] (the image is only an example from internet)
Approx. slab dimensions are 45 x 30 m and thickness is 250 mm. Thickenings are Height x Width = 330...
Hi comrades :)
Designing a retaining wall.
Structural layering from top to bottom: the cast-in-place retaining wall base > blinding (weak concrete thin layer or geotextile) if necessary > crushed rock pad 0,5 m mainly to avoid capillary effect, but have to be compacted properly to provide good...
Dear forumers
I have a general question about CFD simulations. I am a Structural Engineer in a field of Construction. Recently I see a lot of video presentations about CFD simulations for special structures like for example high-rise buildings. A main message of the presentations is CFD...
Hello colleges
I have quite a basic connection like that below. I haven't made steel quite a lot of time, hence forget some special detailing requirements.
I remember in some cases I used an elongated notch for the tongue plate, but I don't remember exactly what for. My memory gives a clue...
Hello
Do anybody model the supports by point support in corners of the walls instead of line support along bottom edge? Are there any advantages? I mean global analysis of buildings.
Best regards
Hello
For moderators. I am not sure that the question is for current section of the forum. If it is not, please move it where it should to be.
Are there any software at the market that can perform CFD simulation of the metro train departure/arrival? The result of the simulation should be...
Hello
I am designing a joint of two precast walls. The joint should be capable to resist a bending moment of about 13kNm. The joint is not a very good solution, but this is a desire of a client.
I have worry about a shear capacity of a corner due to a compression component of a couple of...
