DAYTON, Ohio (AP) -- The University of Dayton is reinforcing floors of hundreds of student houses after the floors of two houses sank during large gatherings.

The university says it will take about two months to shore up the floors of 301 student houses near campus. UD is calling it a "precautionary measure."

The Dayton Daily News ( http://bit.ly/VoCl7O ) reports that students won't have to move out during the work, which is expected to start next week.

Students reported sinking floors in two of the houses during large parties earlier this month.

The university said previously set occupancy limits for the houses will likely be adjusted once the floors are reinforced.

UD began buying homes in the early 20th century neighborhoods near campus in the 1970s.
