7 Performance Based Design is implemented in FD 13 according to Turkish code. This way the performance level of existing RC buildings can be calculated from linear analysis. To calculate Performance level of an existing reinforced concrete building, follow these steps:
8
9 1. Set the code to “Eurocode (Seismic code: Turkish)”.
10 1. Build the model in Structure tab.(((
11 |(% style="width:111px" %)[[image:warning.png]]|(% style="width:1339px" %)The columns and walls have to be defined from storey to storey.
12 )))
13 1. Add the loads in Loads tab.
14 (% start="1" style="list-style-type:lower-alpha" %)
15 11. Define Gravity load combination.
16 11. Define masses from loads in Load case – mass conversion dialog.
17 11. Define the Seismic Load properties:
18 (% start="1" style="list-style-type:lower-roman" %)
19 111. Set the Structure type to Existing building, and also the Information level in Structure information tab.
20 111. Define the design spectra in Spectra tab.(((
21 |(% style="width:85px" %)[[image:light.png]]|(% style="width:1285px" %)There are Standard and Unique spectra. Standard spectra are calculated according to the current seismic code. In order to define non-standard spectra the use the Unique option.
22 )))
23 1. Run analysis in Analysis tab
24 (% start="1" style="list-style-type:lower-alpha" %)
25 11. Calculate Load combinations in Calculation dialog.
26 11. Calculate Eigenfrequencies in Calculation dialog.
27 11. Calculate Seismic analysis (//Equivalent seismic load//) in Calculation dialog.
28 1. Define reinforcement for RC elements in RC Design tab.
29 1. In Performance based design tab
30 (% start="1" style="list-style-type:lower-alpha" %)
31 11. Set the Calculation parameters for beams, columns and walls:
