Member Global Density

The member global density is selected from the Properties menu. This will bring up the Global Data panel in the right hand side of the screen. The global density is based on the E value of the materials in your frame which are defined when you choose a section material. If the E value is greater or equal to 200, then the material is assumed to be steel at a density of 77 kN/m3. Similarly, for E between 20 and 200 concrete is assumed and for E below 20 it is assumed to be timber. These values are editable.

If you don’t want the density to be included automatically untick the Include Member Density box. The columns are usually included in load group D1 or D0 if pattern loading is being considered. Members other than columns are in the D1 load group.
