Building will be introduced later.
AutoCAD Settings
Drawing layers of structural objects are imported from Autocad Settings on Tree View.
Click “Import Drawing Template” and select a drawing template to import layers as shown below.
Materials
There are common used steel and common used concrete material definitions in Building Design Suite library. Definitions must be imported in order to be used as shown below.
Go to Materials section → click “ Material DB” → select ASTM A615 Gr60 and Conc 4000psi → click “import”
You can also add custom material definition as shown below.
Go to Materials section → click “Add”
Enter values of material properties
Name the material
Or you can create your own material database;
Launch OpenBrIM app
Log in with your Buildin Design Suite account
Click Authors → Select your account name
Create new project → go to ParamML tab
Now we will write parametric definitions of materials and add them to database. There is no need for new release to use new material definitions that we will add.
Overview of Building Design Suite material database. Our new database should be like this;
This is how our empty object looks like;
Add Database=”AEC_Material” to first line as shown in Building Design Sutie material database. This state indicates that our project is a “AEC_Material” type database object.
You can search core objects by typing words after “<“ or you can write objects manually. Objects must start with “<O” and end with “</O>” .
Write unit objects to be assigned as unit category to materials as shown below.
Default core unit object is shown above. You can edit name and other parameters as you need or you can write unit object which have all parameters shown above manually as shown below.
Parameters will be calculated in units of assigned unit category. Unit object example shown above will be assigned to material’s parametic definitions as unit category. You can write more than one unit object and assign each to different parameters.
Write group object by searching from core objects or manually as shown below. Select “CORE OBJ: Group”.
Give name to group object. Since we are going to add more lines inside the group object delete “/>” in the line 4 and type “>” instead. We must type “</O>” at the end of object. We are going to define one steel material object and one concrete material object in NewMaterial group.
Write first material object by searching as shown below and Select “CORE OBJ: Object” or write object manually.
Name the object as” NewSteel” since we will define steel first and change type of object with ‘T=”AEC_Material”’ to be able to see this object in Building Design Suite import list.
We must assign our object as steel by a parameter and add steel properties by writing patameters for each property.
Write parameters by searching as shown below and select “PARAM: Parameter (Numeric)” or write parameters manually.
Steel material object should be as above.
Rebars
There are rebar definitions in Building Design Suite library. They are also must be imported in order to be used. Process is the same as importing of material definitions.
Go to Rebar section → click “Rebar DB” → select rebars → click “import”
A material must be assigned to rebars to avoid errors during analysis. Assign ASTM A615 Gr60 as shown below.
Load Classes
Load classifications are added from load classes section as shown below. Add 2 load classes.
Go to Load Classes → Add
Choose first load class as SDL and name it
Choose second load class as L and name it
Self Weight class is being created automatically at the start of project.
Loads
Load properties based on loading schedule are added from Loads section as shown below. Add 4 loadings. SDL is 20 psf LL is 40 psf for residential areas, SDL is 35 psf LL is 60 psf for terrace, LL is 100 psf for public escape areas but will be loaded as sum of 40 psf LL + 60 psf LL.
Go to Loads section → Click “add”
Select load class and type
Enter value of load
Name loads
Load Combinations
Design forces are determined by load combinations. We will use 1.4D +1.4 SDL and 1.2D+1.2SDL+1.6LL combinations. Add load combinations as shown below.
Go to Load Combinations → Add
Enter load factors to load classes
Name load combinations
Drawing Files
Upload reference drawings as shown below.
Go to Drawing Files → Upload Drawing
Select reference “.dwg” files and click OK
All necessary datas have been defined to start modelling. We will start drawing.
Stories
Create stories to draw as shown below.
Go to Stories → Add
Enter number of Stories
Enter elevation of each story
Assign drawing file
Select default materials for slab, column and slab rebar
Description based on floor plans will be added later.
