I'm trying to model one way reinforced concrete slab, firstly I made the step static general but the solution is aborted due to the time increment needed is low so I changed to dynamic implicit and applied a velocity -100 mm which is obtained by experimental work. the problem is i didn't get reactions at supports and the value of the load at loading supports is very high, the load from experimental is 1 ton and the load displacement curve is not logical how can I fix this. the units in model N mm. iattached photo of the reaction force and RT with time and the model
Check the following link, you may able to tackle your problem there:
Book Reinforced Concrete Slabs Under Impact Loading
the loading rate (velocity) is two high (see the deformed shape)
You need to reduce it
Also I recommend using abaqus\explicit solver for quasi-static problems
If you want to use general static, check boundary conditions (you need restrain some points of the model from moving that you expect it does not move like restraining movement in x direction)
