A Step-by-Step Guide to Modeling and Pushover Analysis of Eccentrically Braced Frame in SAP2000
An eccentric brace is a structural brace that is connected to the frame at an eccentric location.
This means that the brace does not meet the frame at its centerline.
The eccentricity of the brace creates a moment arm, which allows the brace to resist
lateral loads more effectively than a concentric brace.
Steps:
1.Modeling
a. Grid
b. Define sections
c. Hinge definition
d. Defines BC
2. Loadings
a. DL 10kN/m and LL 15kN/m
b. Pushover load or lateral loads
3. Load cases:
DL, LL, and Pushover.
4 Analysis Perform and results.
a. Pushover curve
b. hinge response
