    Equivalent Static Method vs. Simplified Method in NBCC 2015

    Hello, I'm struggling to figure out the simplified method vs the equivalent static method in the seismic portion of the 2015 National Building Code of Canada. The seismic hazard index is listed as IeFsSa(0.2) and IeFsSa(2.0) (Cl. 4.1.8.1 (2)). If these values are less than 0.13 and 0.03 then...

    Assign Acceleration to Node

    Hi, I would like to assign a sine function acceleration to a specific node in my structure instead of the ground acceleration that is the default for time history analysis. How can I do this? Thanks!

    Calibrate model to give desired frequency

    I have a simplified model made in SAP2000 of a small structure that I constructed. The structure consists of 3 levels above ground level. Each storey is 400mm in height so the total height is 1200mm. The columns are continuous from the base to the top of the structure and are made of steel...

    Variables affecting modal frequency and shape

    I have modeled a building, applied a horizongal sinusoidal load to the top floor causing the building to vibrate, and am trying to make sense of my results (fundamental frequency and mode shape in particular). I want to make sure that I have the relationships between different variables correct...

    Simple Dynamic Analysis Problem

    I have a simple dynamic problem that I'm trying to do in SAP2000 to make sure I know what I'm doing before modeling a more complicated structure. I cannot get the correct first modal frequency from SAP. Here is the problem: A lamp post is 12m tall, fixed at the base, with a 7.5kg lamp at the...
