# Step 3: Loads

# Self weight

Edit the self weight of the wall:

• In the BLOCKS tab in the ribbon, choose the wall block named "200 mm C30 S500 2xØ8/400 S500 2xØ8/250" (or any other wall block).
• In the wall block properties the default value of Weight [kN/m³] is 25.
• Load from masonry, insulation etc. acting on the façade is added by changing Surface load [kN/m²] in Vertical surface load to 2.

# Load types and load definitions

Create load definitions:

• In the LOADS tab in the ribbon choose Define loads.
• In the load types table, add four more load types by pressing New.
• Change the names, Categories and Nominal loads as pictured below.
• In the load definitions table, add another load definition by pressing New.
• Change the names and included load types as pictured below.

# Assign loads

Assign the load definitions to the model:

• In the LOADS tab in the ribbon choose Assign loads.
• Choose the create mode Surface load in the ribbon.
• Choose the Load definition named "F01 Office" and assign it to the decks on level 2, 3 and 4 by clicking on the decks.
• Assign the load definition named "R01 Roof" to the deck on level 5.

# Horizontal loads

Create horizontal load cases:

• In the LOADS tab in the ribbon choose Wind generation.
• Create a new set of in plane horizontal loads by selecting "D (4 - 6) (Level 1 - Level 5)" in the table and pressing New load for selected wall.
• Rename the new set of loads from "(user defined)" to "Wind+".
• Change Shear forces [kN] to 20 for the top level and 40 for the three others.

# Lateral wind loads

Lateral loads are assigned to the concrete elements (panels) via the properties.

• In the LOADS tab in the ribbon choose Assign loads.
• Select a panel in the wall. In the Model outline on left hand side, Wall 1 is highlighted.
• Expand it and click Panels. All panels in Wall 1 are now selected.
• In the concrete element properties locate Second order analysis options and change Characteristic lateral load [kN/m²] in to -1.5.

A positive value is pressure on the front side of the panel and negative is suction. The blue z-axis in the local coordinate system on the wall points towards the frontside.

• Ensure that Lateral load category is V (Wind load).

Next step is setting up a load combination and making a calculation.
