In the context of seismic design regulations, ASCE 7 allows for an exception in certain cases regarding the design of Steel Ordinary Cantilevered Column Systems. Specifically, in Seismic Design Categories D and E, ASCE 7 permits the use of provisions outlined in 12.2.5.6, typically reserved for...
If I recall correctly, the intent for Type 5 horizontal irregularities is to properly account for elements that are acting as the LRFS in both axis or are non-parallel. Offset T cantilevers (10ft cantilever in one direction and 5ft cantilever in the other direction) certainly have torsional...
I am working on a project where the owner would like to turn an existing single story warehouse into a multi-story office building that has existing insulated precast panels around the exterior. Based on the GPR, the panel has a very similar profile to the attached image. Where the existing...
When designing structural rod bracing, I feel like it's necessary to determine what compressive load results in plastic deformation of the shape to verify the shape can elasticity recover in addition to the other bracing related checks. However, I do not see this done often. What am I missing or...
