Hey everyone! There's a possibility I have to design a large manufacturing building with external dimensions of approximately 141x182 m. It'll probably have RC or steel columns, steel trusses for roofs and metal deck on top of these trusses. The building also houses a lot of cranes, a few of...

Hello everyone! So I'm designing a steel grain silo with a capacity of around 33 m³ for the vertical part (class 1 according to EC 1991-4, under 100 t) - the cross-section is 2,0x2,6 m and the vertical section is 6,75 m high (so the grain would weigh around 300 kN at a unit weight of 9 kN/m³) ...

Hey everyone! So I'm designing a factory that has a vibrating equipment on one floor. The load is given like this: Do you have any thoughts what that "6 pol" might mean? I'm not too familiar with dynamic analysis but am trying to educate myself a little in Robot Structural Analysis.

Hi everyone! Perhaps you have some helpful suggestions. I'm designing a facility that has some wheat silos on top of sway frames. The frames itself are about 7 m tall and span 5 m, but the loads from the silos are really large. In my calculation model all the joints are currently hinged. Below...

Hey everyone! What the buckling lengths for member B6 and the top half of B7 should be? All supports are pinned and currently connections between the beam B8 and its columns are pinned as well. B6 is about 13 m high.

Hey everyone! So the contractor wants I design a roof with a two-sided 6° inclination using hollow core slabs - he thinks he'll have easier time with the insulation this way. Below is a preliminary section of the building. The yellow ones are hollow core slabs that span ~7 m and they are...

Hey everyone! So I have a situation where I have a rather large but simple building with RC columns and steel trusses. The building is unheated, it's like a riding ground for horses and there is an area inside next to the exterior wall with masonry walls. The walls run near the columns. The...

Hey everyone! Is there some way to estimate the capacity of the joint seen on the drawing below? A force is applied to the notch, which puts the area near the cut in tension perpendicular to grain.

Hey everyone! I have a chance to quote for a design of a 30 m high steel billboard column. It's located in Denmark, and the reference PGA in this particular area is agR=0,1 m/s². The design wouldn't be nothing too complex if it wasn't for the seismic part, which I've never done before. That's...

Hey everyone! So I have to solve a problem with a firewall between two buildings. I cannot tie it to the buildings on both sides so it has to be free-standing. I'm thinking about 240 mm CMU filled and reinforced blocks but even just with these the slenderness is about 2,8 times over the allowed...

Hey everyone! This is sort of a different thread, since I'm not asking advice on any particular problem but would just like to hear some general opinions. It's about steel roof trusses that develop compression in the bottom chord due to uplift from wind. The out-of-plane buckling length is...

Hey everyone! Perhaps you can help. I have this timber beam that has to be spliced since 7 m long elements are not available. I want to make a 1,3 m overlap, that has 2 bolts at each end of the splice so the bolt groups are spaced 1 m apart. Is this thing viable? I need to design the bolted...

Hello everyone! I'm an Estonian and my company was asked to put together a quotation for a project in English. We do building design. I'm having some trouble translating some specialized vocabulary to English, so perhaps you can help. 1) How do you call like a topographic/geodetic survey of a...

Hey everyone! So I have this rather long (~100 m) two-storey building. It's supported by RC columns. The second floor is made up of RC beams and hollow core slabs. The roof has steel trusses. The columns are spaced 6 m and 12 m. It has a masonry wall running in the middle across the building...

Hey everyone! Perhaps you can give some advice. I have a heavily loaded RC beam with a 5,6 m span with a design moment of around 1000 kNm. I calculated I need to use 8 D25 B500B main bars in the bottom. I want to place them in the mid-section of the cross-section because I use Peikko's PC beam...

Hey everyone! So I have to design this two-storey storage building. The second floor is made of precast RC beams and support ~12 m 400 mm hollow core slabs. The roof is supported by ~12 m steel trusses. The building is about 10 m high. Anyway, my question - is an expansion joint needed in a...

Hey everyone! So I have to design a steel platform that's going to be used for supporting large log grapples for maintentance. The grapple weighs 150 kN or around 15 t. I'm thinking about applyling four point loads to the structure which arise from the grapple legs. But my main question is how...

Hey everyone! So I need to design a house and the client wants the interior to be spacious. The problem is, I'm not too familiar with timber design and I can't really decide if the frame I drew is even feasible with timber. So I came here to get some advice. My main problem is in-plane...

Hey everyone! I have a situation where a Soviet era RC beam (it's sort of like a truss, where the chords are wider than the middle part of the beam) has its bottom chord cut with most of the rebar and cables cut - seems it was done a while ago to fit a goddamn door, thank god it has stood this...

Hey everyone! Do you know how well would Tekla run on a rig like this? To my experience the graphics card usually does not affect Tekla's performance much. I'm eyeing a desktop with such specs.
