She was aged 27.
Ms Beary died after suffering a stroke in Dublin.
Ms Beary had experienced life-changing injuries after a fourth-floor balcony collapsed in June 2015 while she was celebrating her 21st birthday.
An investigation later found that joists supporting the deck were suffering from dry rot and had been constructed by a company with a history of complaints.
In recent years she became an advocate for construction reform in California.
Ms Beary and her friends had been visiting the US under the popular J-1 summer working visa programme when the tragedy struck.
The balcony had been constructed by a company that had a history of legal claims against it and which it had not disclosed to the Californian state licensing board that regulates the building industry.
Five Irish students and one Irish-American friend were killed in the collapse, while seven others suffered a range of serious injuries.
In 2015 the families of those killed reached a confidential settlement with the companies involved in the building’s construction.Aoife Beary was left with a traumatic brain injury, broken arms, hands, pelvis and jaw, as well as lacerations to her liver, kidneys and spleen, a collapsed lung and broken ribs.
She later underwent open heart surgery.
In 2016, she testified before the California state legislature during a hearing on legislation to force building contractors to be more transparent about past legal claims against them.
During emotional testimony, she told legislators how she had lost much of her independence after the accident and that her career goals had been ended.
“My life has been changed forever,” she said.
She also recalled how she and her friends, who she had known since the age of four, had travelled the world together.
Aoife said that her birthday would now “always be their anniversary”.
