. This opens the dialogue for the load groups.
- Enter the moment [days] when each load group becomes active in the column t0. The number of days should be counted from the day the concrete was cast.
Do this for all load groups, otherwise the calculation will get stuck in a later step.
If a load group is empty or you don’t want to take it into account, delete it
.For variable loads, Diamonds assumes that at t0, the quasi-permanent part of the load acts. - Choose a combination for cracking. The more time passes and the more the loads increase, the more the cracks. However, this amplification over time cannot be taken into account accurately. For each load group, the increase of deflection over time (creep effect) is calculated with a single cracked state, caused by a given combination of loads. You select this load combination (mostly SLS RC 1) in the last column of the dialogue.
