Default a problem with adding fields in ssems

i have a DB and it has some tables that the tables has related link (diagram).now when i wanna to change a table's field , the Sql Server errors that the table is not empty.when i try to delete the table's content , Sql server errors that the table is use a relation with another table.
so can i change a table's structure?
by the way before i forget , the Sql Server's error is below:

'UserManagement' table
- Unable to modify table.
ALTER TABLE only allows columns to be added that can contain nulls, or have a DEFAULT definition specified, or the column being added is an identity or timestamp column, or alternatively if none of the previous conditions are satisfied the table must be empty to allow addition of this column. Column 'isadmin' cannot be added to non-empty table 'UserManagement' because it does not satisfy these conditions.

Based on the error message that you get, when adding a column in a table that already contains data, you have to either allow NULLs on that column or you have to specify a default value. Here's how your ALTER TABLE will look like, adding isadmin column with a default of 0 (assuming this is a bit column):

ALTER TABLE UserManagement ADD isadmin bit NOT NULL DEFAULT(0)
