Hello everyone,
I've tried to find a good reference to understand, if it is nedeed to consider accidental torsional moment in the seismic design of an industrial building, with flexible diaphragm.
Regardidng industrial buildings we do not consider any rigid diaphragm, instead we use roof...
Hello!
I am currently working on a PEER review for a steel moment frame building. In the past, I used to check isolated footings against overturning moment, no matter if they are below grade. At this time, there is a dicussion with the EOR, since he thinks that overturning only affects footings...
Hello Everyone,
Imagine we have a steel primary beam running parallel to secondary beams. The floor system is a concrete-filled metal deck and is attached to the primary beam via shear studs. Under lateral loads, this beam will experience double curvature. If the beam was not attached to the...
Hello Everyone
I'm trying to find a plan configuration of real structures with extreme torsional irregularity Type 1a or 1b. Has any of you dealt with this problem, that could provide some information?
I'm starting to believe that is difficult to find structures with Type 1b in real world...
Hello Everyone
It is known that all of the tests for the prequalified connections were done using cantilever beam specimens. I'm currently studying the effect of weld restraints, and my concern is: will the behavior of a moment connection on a cantilver beam (free weld restraint in longitudinal...
Hello everyone
I'm designing a structures with a special moment frames system. One of the frames is coinciding on a basement wall (please see attachment), the question is:
Should I detail de basement wall for a base shear, including the omega overstrength factor of the special moment frame? I...
Hello everybody,
I'm currently on a proyect where there's a frame which coincide with a basement wall. We´re modeling the basement wall and providing pin supports, the thing is, should I dimension my piles for the reaction (shear force) obtained form that model? or should rely on the soil...
Hello, everyone.
Just for general knowledge, I would like to know what's the most common practice in your area to transfer column shear loads trough base plates into piers,I know there are three main ways to achieve that and all of the three have something to be concern about.
1.-Shear...
