I'm designing a braced steel structure assigned to Seismic Design Category "D". The structure utilizes special concentrically braced frames (SCBF) for the vertical elements of the seismic force resisting system. Lateral seismic loads are delivered to the SCBF's by horizontal bracing members, not...
For a structure assigned to SDC "D" does the overstrength factor apply to the design of the foundations for the columns in a Special Concentric Braced Frame (SCBF)?

What is the correct time interval to use when designing a roof drainage system (i.e. roof drains, gutters, roof conductors, etc.) in a coastal climate? The 2009 IPC states that the 100 year 1 hour storm event shall be used. However, it seems that shorter time intervals (e.g. 5 minutes) should be...
