Residential students of Dhaka University's SM Hall demonstrated in the early hours of Monday against outsiders staying at the dormitory.
They demanded that outsiders and non-students vacate the hall immediately.
More than 400 students are forced to stay at the hall's veranda because of acute seat shortage.
SM Hall authorities later ordered outsiders to leave immediately, and gave non-students, whose studies had been completed, three days to move out.
So far, 132 outsiders left the hall.
Several demonstrators said the protests started shortly after the nor'wester hit in the evening and their books and beds on the veranda got drenched.
Agitated students gathered in the dormitory’s TV room and shouted slogans against outsiders and demanded they be given seats.
Hall Provost Prof Mahbubul Alam acknowledged that accommodation was a big problem. "Students suffer in rain and winter. We are working to solve this issue," he added.
He said they have already vacated a number of seats and were taking steps to distribute them among the legal and current students.
