Hi all,
Does anyone have any good references or documents that discuss the lateral action of a timber quonset hut with no side walls (half cylinder) in the longitudinal axis. See picture attached below, imagine that but without the steel and instead glulam arches with a timber diaphragm.
Is that assuming the chord deflects about its weak axis because of the kicker brace installation? Consequently, does the first mode shape then induce more weak axis bending because of the axial compression induced from flexure? If the kicker brace were installed to the bottom chord, I'd expect...
100%, the beam span is too long and tributary width too large for a W410x60.
That makes a lot of sense. I'll pitch this to my boss and see where I can take it.
Hi all,
I am currently working on a retrofit to a 50 year old steel building. After performing design calculations on an ex. W410x60 beam that has a laterally unsupported bottom flange, I realized it fails in negative bending. It is 2 span continuous with an 8 m and 6 m span. The condition is...
I'm designing a structure with glulam arches @ 4'-0" o/c along the longitudinal axis. I've created my model using the continuous arc template with 10 arc increments. After loading each arc with gravity load and running the analysis, the program is not treating the entire member as continuous...
