NRL: The Brisbane Broncos staged an incredible comeback to beat the Panthers, ending Penrith's remarkable run of consecutive Premiership wins.
Suncorp Stadium has responded to safety concerns after Brisbane’s premier venue was physically shaking during the Broncos’ record-breaking preliminary final win against Penrith on Sunday.
The Broncos booked a spot in this Sunday’s NRL grand final against the Melbourne Storm in Sydney after securing an epic 16-14 comeback victory against the Panthers.
The 52,491-strong crowd was the largest for a Broncos game in the stadium’s history since the 2003 ‘Lang Park’ redevelopment and just nine people shy of Suncorp’s 52,500 capacity.
The Broncos looked destined to be knocked out of the title race after trailing the reigning four-time premiers 14-0 at halftime before launching a spirited comeback.
Broncos captain Adam Reynolds slotted a clutch sideline conversion in the 77th minute with scores locked to deliver Brisbane a shot at grand final redemption.
At fulltime as the Broncos’ victory song played, patrons at the venue could feel the stadium shaking and rocking – similar to an earthquake sensation.
Suncorp Stadium’s foundations were literally shaking on Sunday.

But the stadium’s acting general manager Julie O’Keeffe allayed concerns about the stadium’s integrity and said it was designed to move.
“Stadiums, like most structures, are built in a way which allows them to flex,” she said.
“It’s a credit to the NRL, the Brisbane Broncos and especially their members and fans who created such an electrifying atmosphere.”
The crowd was the largest for a non-State of Origin game at Suncorp and only eclipsed by pop singer Ed Sheeran, whose concerts of close to 60,000 include patrons on the stadium surface.
One of Queensland’s top engineers, Professor Dane Miller of Structural Diagnostics, said the stadium’s movement was part of the design.
“What spectators are feeling is the natural vibration of the stadium responding to tens of thousands of people moving in unison,” Dr Miller said.
“Modern stadiums are designed with this in mind, and the rocking sensation is a sign of the structure doing exactly what it was engineered to do.
“Large stadiums are designed to be flexible, rather than rigid. When a crowd jumps or sways together, the structure absorbs and disperses that energy. It’s the same principle that makes tall buildings safe in high winds.

“It may feel dramatic to spectators in the stands, however it is a predictable phenomenon and load consideration during the design process of this type of structure.
“There are also significant factors of safety built into the relevant codes which govern the prediction of loads and the design of structural elements to carry those loads.”
