Walterstj Posted January 27, 2018 Share Posted January 27, 2018 I am building a platform out of metal trussing... It's says 320/20, which means I can go 16 blocks before it falls apart... But a 16x16 square won't fill in without falling apart... If it's really 320/20, I shouldn't need pillar supports in the middle... Where am I going wrong? Thank you fellow slayers Link to comment Share on other sites More sharing options...
Outlaw_187 Posted January 27, 2018 Share Posted January 27, 2018 I could be wrong but I was thinking I heard Skippy or cage or someone on YouTube say it was 13 or 14 that you could go out with metal trussing. Never tried it myself though. I see where the math says 16. IDK man, got me on that one. Hope you get it figured out. Link to comment Share on other sites More sharing options...

Thank you fellow slayers I'm still learning how this works myself, but I can share what I've seen from my own experiments. I was working with cobblestone frames which can go 8, but the physics are the same. Basically, you can build a support and then place 8 blocks in either or all of the four directions off of it. however, when you try to fill them in to make a solid roof, you can only get three or four layers in until it collapses. This is because a block can only support the maximum when it's already supported as part of the column. For some reason, all of that changes if you build off of a wall. If you start with a full one, you should be able to build 16 in one direction and build a column. Go another 16 either left or right and build another column, then connect back to the wall and you'll be able to fill it all in with no problem. Rinse and repeat from there and it should work. I'd love to hear back of you try it. Like I said, I'm working it all out myself. Link to comment Share on other sites More sharing options...
Walterstj Posted January 27, 2018 Author Share Posted January 27, 2018 I'm not sure I'm following you.... I'll have to upload some pictures... I have 4 columns made of trussing metal blocks... There are 16 blocks between the posts making a square... I cannot fill the square in without it collapsing... I guess I'll have to put more support columns in the middle or are you saying the edges need to be full walls that make the outside edge of the square? I've watched a video on YouTube about blocks and I thought I was going in the right direction until it collapsed twice... First I thought it was because I was building as I stood on it and it couldn't take the weight until it was finished... But it collapsed on top of me the second time...

PO_Man_3849 Posted January 27, 2018 Share Posted January 27, 2018 Try starting on one wall and go 8 blocks, then start from the other wall and meet in the middle. Once you place the last block to connect them it should figure the structural integrity based on the 2 supports? Worth a shot... Link to comment Share on other sites More sharing options...
Walterstj Posted January 27, 2018 Author Share Posted January 27, 2018 [ATTACH=CONFIG]23867[/ATTACH] here's the configuration... I can make the square, I just can't fill in the void... by what I've read so far, I guess it can't be the maximum number of blocks? I was under the assumption as long as it's supported on both sides, it could be, it's never not worked with any other block, although, those are far shorter spans - - - Updated - - - And my next question would be, if I do have to fill in the outside area to make it a total wall, as long as the trussing is at the top, the block math should still work? - - - Updated - - - And yes I tried to go from both sides... and I've tried building from the top and from the bottom, always crashes down Link to comment Share on other sites More sharing options...
GRAW2ROBZ Posted January 27, 2018 Share Posted January 27, 2018 I always use a support pillar after every 5 wood frames. Just a force of habit. Link to comment Share on other sites More sharing options...
Walterstj Posted January 27, 2018 Author Share Posted January 27, 2018 For regular building I only go 6 blocks before a support, but I am just tripping over the math for the block itself... Wether it's east, west, north, south, the block says it can handle 16... So no matter what way you go, there's only 16 extending out before "support" block... I guess I'll have to go and change the width and see what that does... I'll let y'all know... I asked the same question in the bug section, we'll see what they say Link to comment Share on other sites More sharing options...
jackleroy Posted January 27, 2018 Share Posted January 27, 2018 If you make at least one of the sides a wall, it should work. That's what it took to make my cobblestones stay up. I'd go with one or both of the longer ones that you have. Link to comment Share on other sites More sharing options...
Walterstj Posted January 28, 2018 Author Share Posted January 28, 2018 I had to split the difference and add supports going both ways... So every 8 blocks, there is another column... In a straight line, 1 row will extend 16 blocks, maybe 2 rows. But not the whole 16x16 square... Link to comment Share on other sites More sharing options...
PO_Man_3849 Posted January 28, 2018 Share Posted January 28, 2018 When you started making the structure did you place the first blocks on the ground? I read before you have to dig down to solid Rock to be able to get full stability Link to comment Share on other sites More sharing options...
Walterstj Posted January 28, 2018 Author Share Posted January 28, 2018 Yes, I made the 4 corner "posts" 6 blocks high... Then made the 16 block square... The first time I tried to fill the square from the top, I assumed it was my weight that caused it to collapse... Second time, I tried to fill it from underneath, and it collapsed on me... I put the "center" posts 8 blocks in the middle and it worked fine... The mass must screw with the block math somehow Link to comment Share on other sites More sharing options...
Mr8liner Posted January 29, 2018 Share Posted January 29, 2018 Try this, start in a corner do 3 blocks wide all the way around. Then do 2 more all the way around. At this point you should have 6 blocks left,either direction. From there count 3 blocks and put a truss do the same thing on the other side. Then connect them one on each side at a time. At that point you should be able to fill the rest in. I do this with concrete blocks and don't have a problem. When I upgrade them I go 5 wide all around, let cure then repeat until it fills in Link to comment Share on other sites More sharing options...
ZombieHoG Posted January 29, 2018 Share Posted January 29, 2018 If you make a square 16 wide between 4 pillars in the corners, there are 16x16 blocks (that's 256!) connected to 8 supported sides (4 pillars, 2 sides each). The math says: 256 blocks minus 4 blocks (these are supported) each 20 mass gives 5040 weight. You got your 8 supported sides: 5040 divided by 8 is 630. This has to collapse! more info: https://7daystodie.com/forums/showthread.php?20701 and youtube with '7d2d structural integrity' and be warned: unsupported 'arms' will only reach out 14 blocks (as long the weight is considered and ok), unless you do an extralayer for each additional block.
