I am not familiar with track homes, but someone I know is. He claims that everything they do are always close to stress level since the material cost becomes significant when they build hundreds of the same houses. "Barely meet code" was the law to be kept employed. On the other hand, I am...
Just an update, our project manager/construction intervened and had the same cost concern. The HSS are gone, we will use 6-in wide flanges instead. Thank you everyone.
Thank you all for the reply. As for the forklift, it would be highly improbably to have a forklift hit this particular stair. It would be outside, immediately next to dirt. Large entrances are on a different side of the building. There are large vessels beyond the dirt, that would block...
With an L4x4x3/8, Im about 2% over stress. Using the L5x5x3/8, I'm down to 62% stress. My highest landing is about 16ft off the ground. My loading is 100psf live load. The ease of connection is my original argument against HSS. I will be bracing the columns regardless of shape, so I dont...
I checked bending on the geometric axis. I still can't see how there will be ecc. coming from the platform. Thank you everyone. I think its pretty much a lost cause. But would still like to know if there are other reason.
Thank you for the reply. I do not think ecc. would be a problem since I would be attaching the channel to each legs at the same plane. I would also have diagonal bracings below the landing/walkway. I checked lateral loading from seismic, and they are ok. I do think this is one of those cases...
This is my first post in this forum.
I am currently designing and detailing a steel stair for an industrial project. From a strength point of view, I can use an L5x5x3/8 for the columns. I thought this would make a nice clean connection to the channels supporting the walking surface...
