Hi guys, just wondering what you make of this concrete-filled tube that we found during a frame inspection. It looks like all the side of the column are bulging - indeed it looks like the concrete socle at the base is restraining the deformation which is why some concrete is spalling off. At the...
Hi everyone,
I am checking a steel crane beam in an old theater. It is about 21m long and is supported in 3 intermediate points for 4 continuous spans of approx 5m. It is connected at these points to perpendicularly spanning concrete beams by way of channel sections, welded vertically to the...
I am detailing a portal frame that has HEB260 columns and IPE600 rafters. I am trying to detail the proper restraint to the columns at the level of the base of the haunch. I am using SCI documents P397, P399, and P252 (which all pertain to portal frame design) as references but I have some...
Hi guys,
I have a beam that is installed already but needs to have the flanges on one side of a 500mm long section of it removed to make room for a pipe. I am using SCIA Engineer FEM package and I would like to check that there are no adverse buckling effects etc from this flange removal...
Hi, I have a need to "hang" a steel beam from two concrete beams. The top of the steel beam is 110mm above the top of the concrete but the beam needs to be at least 330mm deep so I was thinking to taper the beam ends and sit it on top of the concrete. There is a picture attached that hopefully...
Hi guys,
