Load Classes

Load Classes classify loads to be multiplied by factors in the load combination section. (It is analogous to “Load Case” in most of the FEM softwares.)

Load classifications are added from load classes section as shown below.Self Weight class is being created automatically at the start of project. Add more load classes.

  • Go to Load Classes → Add

  • Choose the load class abbreviation for each added load class

  • Add SDL

  • Add L

  • Add L_Assembly

  • Add Lr

  • Add L_Heavy

AEC | BOLT Building Design Suite reduces live loads in accordance with NYCBC 2014 if live load reduction is set true by user. For further information see Live Load Reduction .

If live load reduction is set true and live load reduction template is imported from the library, live load results are reduced by calculated reduction factor.

 

 

Loads

Load properties based on loading schedule are added from Loads section as shown below. Add loadings.

  • Go to Loads section → Click “add”

  • Select load class and type

  • Enter value of load

  • Name loads

 

 

 

You can also import loading definitions from AEC|BOLT BIM Cloud library.

  • Click Load DB

  • Select loads → Click import

You can create your own loads database on AEC|BOLT BIM Cloud library.

 


Load Combinations

Load combinations and envelopes are defined in Load Combination Tables section.

Add load combinations as shown below.

  • Click Add

  • Enter load factors to load classes

  • Name load combinations

You can import combinations from AEC|BOLT BIM Cloud library and also you can create new combination database for your project on AEC|BOLT BIM Cloud library.

  • Click Combination DB

  • Select combinations

  • Click import

AEC | BOLT Building Design Suite allows user to add load combinations or envelopes to another load combination. To see and add load combinations and envelopes columns to spreadsheet;

  • Click Showing w/o L.C. and click Showing w/o Env.

The algorithm prevents the definitions which cause circular dependency. The cells that cause the circular dependency are blocked by light grey color.

To define envelopes;

 

  • Go to Envelopes spreadsheet

  • Click Add

  • Set YES to add the load classes to envelope

AEC | BOLT Building Design Suite allows user to add load combinations or envelopes to another envelope. To see and add load combinations and envelopes columns to the spreadsheet;

  • Click Showing w/o L.C. and click Showing w/o Env.

The algorithm prevents the definitions which cause circular dependency. The cells that cause the circular dependency are blocked by light grey color.
