there are some preloadings in my model (BOLTED CONNECTIONS) because of unconvergence problem in Abaqus/standard i want to use preloading in abaqus explicit because we can not define preloading (bolt load) in abaqus explicit i decide to use sequential analyse .at first i define bolt load in abaqus standard after that use abaqus explicit to run model.i dont know how i can do it?
You can import abaqus/standard to abaqus/explicit or the other way around by making another model in the same file. you can then remove the load or BC and interaction in the new model. afterwards, you should make predefined field by importing the job in which you have performed the preload in Abaqus/explicit
for more detailed explanation

hope this help
Check abaqus analysis manual->analysis techniques-> analysis continuation technique->import analysis or *Import. However, remember bolt pretension is not available in explicit. Therefore, even if you import from standard after bolt pretension, you wont be able to maintain pretension load/displacement in the explicit step.
Workaround, try using temperature loading to give you desired amount of bolt pretension :)
How did you import from abaqus/standard to explicit, I may have the same problem.
Thank you!
Dear Behnam Karami,
I highly recommend to read the Marko Pavlovic thesis (RESISTANCE OF BOLTED SHEAR CONNECTORS IN PREFABRICATED STEEL-CONCRETE COMPOSITE DECKS), specifically items 5.3 (loadings steeps) and 5.4 (Analyses method).
You can download his thesis by the link below:
