OVERVIEW

It introduces how to get the design force of 1D member including Location of design forces, 1D Design with a irregular shape force and How to find Max. My.

 

Location of design member forces

The locations where basic design member forces are measured are illustrated. It is effective only when a uniform load is applied, but in most cases, accurate design is possible with the following method.

 

1) 0.00L, 0.25L, 0.50L, 0.75L, and 1.00L

2) Location of concentrated load

3) The position contact with other members

It is difficult to predict the location of Max. My if an atypical load such as the image on the left acts.

 

 

 

 

12_4Since Max. My value cannot be found under the following conditions, an incorrect design can be performed.

 

1) 0.00L, 0.25L, 0.50L, 0.75L, and 1.00L

2) Location of concentrated load

3) The position contact with other members

 

 

How to find Max. My

 

 

12_5

 

1) Select a material type.

2) Select a member type.

3) Select a target members.

4) Modify No. of check points in each regions.

5) Click "V" button.

 

12_6> The larger number of check points, the more accurate value can be obtained.
