Per ASCE 7-16 C12.9.1.5, Torsional effects in accordance with Section 12.8.4 must be included in the modal response spectrum analysis (MRSA) and there are two approaches for consideration of accidental torsion...
The first approach is the static procedure where the total seismic lateral forces...
Seth,
Appreciate the response. I'm currently on version 17.00.01.09 SES but will upgrade to 17.01 and see what it provides.
However, it seems if I run a MRSA (CQC) and include the accidental torsion effect (+/-5%), per ASCE 7-10 12.9.5 I don't need to include the amplification of the torsion...
I’m new to RAM SS and at first very impressed with how user friendly it is and how easy it is to setup a model. The current building I’m modeling is a parking garage and at first glance I can tell it will have a horizontal irregularity of 1a or 1b. However, I don’t see where this is shown in...
I have a question regarding precast construction with CIP diaphragm & shearwalls. The job i'm working on has precast elements, beams, columns, Double-tee's...which will be erected before the CIP shearwall & diaphragm are poured. What is the lateral system during the erection process? The...
