Hello all, Natural frequency is required for wind load analysis. However how do you calculate the mass? With full live loads or 0.30*Live like for earthquake analysis.

Thank you very much. So if there is no slender column there is no need to consider this combination right?

Hello all, AS1170.0 includes long term coefficient in one of strength load combinations as 1.2D+1.5*(FiLong)*Q. What is the relations of long term effects with ultimate limit state? Should we use it for serviceability checks? But it is under the ultimate limit state section.

Hello all, Internal wind pressure coefficients for permeable walls are provided in AS 1170.2. Are internal pressures applied to the openings of the walls also by definition? I could not find any definition.

For example if the LRFD load combination is 1.2D + 1.6W + L+ 0.5S, will we replace Dead load with sequential load and obtain 1.2D_SQ + 1.6W + L+ 0.5S? I am omitting super dead loads here.

If you mean non-ductile by non-seismic, you should not add them to your system. If you do so you have to design the system as OMF.

Hello all, Sould I use staged construction (sequential construction) only in service level combination? Or should I also include them in ultimate level combinations and use for design? I think I should because I get positive moment values at the ends of 20th storey internal beams of a RC...
